A green museum is a museum that incorporates concepts of sustainability into its operations, programming, and facility. Many green museums, but not all, use their collections to produce exhibitions, events, classes, and other programming to educate the public about the natural environment . Many, but not all, green museums reside in a building featuring sustainable architecture and technology. Green museums interpret their own sustainable practices and green design to present a model of behavior.
Green museums to help people become more conscious of their world, their limitations, and how their actions affect it. The goal is to create a positive change in the lives of people. They use their position as community-centered institutions to create a culture of sustainability.
Museums make a „unique contribution to the public by collecting, preserving, and interpreting the things of this world,“ according to the American Alliance of Museums ‚ Code of Ethics. There are many types of museums that specialize in various fields, including anthropology , art , history , natural history , science , and can have living collections such as public aquariums , botanical gardens , nature centers , and zoos , or no collections like planetariums , and children’s museums . 
Museums are stewards of natural heritage and cultural heritage by preserving objects of importance to mankind on the community and global level. Museums communicate and contribute to knowledge. They are mission-driven, serve the public, and usually have nonprofit legal status.
In the concept of green museums, the word green means environmentally thoughtful practice. The terms „green“ and „sustainable“ are buzzwords and often used interchangeably. However, according to Brophy and Wylie, „green“ and „sustainable“ have distinctly different definitions. „Green refers to products and processes that are environmentally benign, […] while sustainable means practices that rely on renewable or reusable materials and processes that are green or environmentally benign.“  Another frequently cited definition for „sustainability“ that is used in various contexts by United Nations (1987): „
Sustainability reflects a complex system where components are closely linked and do not exist in isolation from one another. A sustainable system is affected by the individual and collective behaviors of its members. Sustainability therefore recognizes the human impact on the environment , and aims to mitigate negative effects. 
Culture of sustainability
Green museums promote a culture of sustainability. Culture forms and holds humanity’s deepest values, attitudes, and actions. Sustainability asks people to adapt to a cultural level, changing their beliefs and behavior (Worts, 2006). Museums are in a unique role to establish and promote a culture of sustainability. „In their role as authorities and keepers of culture, museums have a power and responsibility to model and teach methods of preserving ourselves, our planet and our cultural resources“ (45). 
Green museums are a relatively new phenomena. Discussions within the area of environmental sustainability began in the 1990s and continued to grow in momentum to the present day. Currently, green museums are receiving a lot of attention from academia and the mass media . Some scholars believe that they have a focus on sustainability (Brophy & Wylie, 2006). However, most of the hotels are located in sustainable practices. 
The green museum movement began in science and children’s museums. Science museums found that environmental advocacy and education fit within their missions and programming. Children ’s playgrounds using green design in their environments for a healthy playground for their young visitors. It has become more and more of a topic of discussion in the area of science, science and culture, and has been realized in their essence.  Recently, the Association of Zoos and Aquariums has revised its accreditation standards to include a requirement for environmental advocacy. 
With the green museum movement beginning in Children’s Museums, The Children’s Discovery Museum in Normal, IL, became the first LEED-certified Children’s Museum on October 3, 2005, when it received a Silver Certification.  The Wild Center in Tupper Lake, NY Was the first LEED-certified green museum in New York, Followed by The Brooklyn Children’s Museum qui est devenu the first LEED-certified museum in New York City in 2008, using Rapidly Renewable and recycled features such as bamboo and recycled rubber flooring. The museum also uses photovoltaics to generate electricity.  The Boston Children’s Museumis also a good example of a leading green museum, after receiving a LEED Gold certification in 2007, as well as the Pittsburgh Children’s Museum , which received a LEED Silver certification in 2006. 
Science museums and zoos were quick to follow Children’s Museums in the green movement. One of the first science museums to adopt green initiatives was the ECHO Lake Aquarium and Science Center at the Lake Champlain Leahy Center in Burlington Vermont, which was the first LEED certified building in Vermont.  The Natural History Museum of Utah is another museum which has taken charge of the green museum movement. They are applying for a LEED Gold certification, and are expected to save over $ 22,000 in energy costs. At their Rio Tinto Center, the museum will have such an integrated design features as an educational energy trail to tell the whole story of energy, as well as a renewable energy system. 
Zoos and Botanical Gardens have also become leaders in the Green Museum field. The Denver Zoo, Woodland Park Zoo, and Cincinnati Zoo all received Green Awards at the 2011 Association of Zoos and Aquariums Conference.  The Phipps Conservatory & Botanical Gardenswas given a LEED silver certification for its new Welcome Center, which „is designed to evoke the geometry of the historic glass houses behind it.“ It has 11,000 square feet of lobby, ticketing, gift shop, and cafe space with a 34ft high glass that is insulated to control glare and heat. Architects partially built the structure into the field, with 14th feet of usable space below ground. It was determined that by doing this, it would be 40-50% of annual energy costs compared to an entirely above ground structure, and that sustainable design could be created. Phipps will also be opening the Center for Sustainable Landscapes, which will be a center for education, research, and administration. It is scheduled to open in the spring of 2012, and is planned to exceed the LEED platinum certification, and achieve the Living Building Challenge . 
Art Museums are now also joining the movement. The Grand Rapids Art Museum has become the world’s first LEED certified art museum complex in 2008 when it received LEED Gold certification, which such innovative features as a heat recovery ventilator, CO2 sensors, and on site gray water reuse.  
Now all types of museums of all sizes are becoming green. In the last decade, 20 American museums have built a new green building or have renovated an existing building with sustainable features. Many others have developed green operations or programming. Some scholars believe that environmental sustainability will become professional expectations for all museums in the future (Wylie & Brophy, 2008).
One specific example of a „Green Museum“ is The Toledo Zoo in Toledo, Ohio. In 2007, the institution redefined its mission statement to focus on inspiring and informing the public about conservation .  As part of their new mission, the Toledo Zoo committed to green construction, which was shown in the parking lot lot renovation project. The main parking lot has been redesigned in order to increase parking capacity, and the project incorporated green elements such as rain gardens and reusing concrete. The renovation also included a residential-sized wind turbine and three solar panels to power the ticket booths at the park’s entrance. The wind-turbine and solar panels generate 3600 kilowatt hours per year, which can be redirected to the zoo’s main power grid when the booths are used. 
Another project at the Toledo Zoo is the Solar Walk. The Solar Walk opened in November 2010 and includes over 1400 solar panels that produce 104,000 kilowatt hours per year, the same amount of energy used by ten typical homes in Ohio.  The Toledo Zoo and the Solar Walk’s design team is keen to see the city and the city. In order to fulfill the project, the Toledo Zoo is a local company, and is used by ODOD to cover the $ 14,750,000 price. Also, The Toledo Zoo, in keeping with their mission statement, included informational panels on how the Solar Walk works and the amount of energy produced to date, so that visitors can be informed about the conservational value of the project.  The Solar Walk will reduce the footprint by 75 metric tons each year, which is equivalent to 15 medium-sized cars.  The Toledo Zoo has further committed to enter green construction into its building plans through geothermal wells, environmentally friendly insulation and other renewable energy and green building materials. 
Museums are taking a more active approach to the development of their exhibits. Children’s Museums Initiated The Green Museum Movement, focused on young visitors. The use of toxic materials and chemicals has become a major concern for both the museum staff and parents. „In its 2004 expansion project the Children’s Museum of Pittsburgh used only adhesives, sealants, paints, carpets, and composite wood that are certified formaldehyde free-near-zero off-gassing.“ 
Before the reduce, reuse, recycle mantra became mainstream, a small number of museums had already begun promoting sustainable decision making thru exhibits. One museum in particular, the Boston Children ’s Museum , developed a concept known as “ The Recycle Shop „. In 1970, this exhibit promoted the benefits of using manufactured materials and turning them into artistic creations. Students, teachers, and the general public were allowed to collect art materials. The Recycle Shop closed its doors after several years in the United States.
Throughout the last several years, exhibitors have expanded their businesses by building eco-friendly exhibits. Using environmentally safe materials Such As low Volatile Organic Compound (VOC) paints, formadelhyde-free wood products and fiberwood (composite wood) are the trademark tools for defining green exhibits. Some exhibit furniture products are also constructed for flat packing . This helps to decrease shipping costs, reduce packing material, increase fuel efficiency which minimizes the overall carbon footprint of the exhibition.
How does a museum understand the criteria that is required? Organizations are working to develop a standard rating system, for the specific needs of green exhibitions. In 2007, the Oregon Museum of Science and Industry (OMSI) created an aid to help museums and the sustainability of their exhibits. OMSI, a scientific, educational, and cultural resource center looked at by the US Green Building Council (USGBC) Leadership in Energy and Environmental Design (LEED) rating system, to create the OMSI Green Exhibit Certification .
The guide provides a checklist for organizations which follows eight elements regularly used in exhibit design. After evaluation, they are awarded 0-4 points:
- Rapidly Renewable Materials
- Resource Reuse
- Recycled Content
- End-life Assessment
- Low-Emitting Materials
- Certified Wood
- Regional Materials
There are other guides and checklists available online for museums that want to be active participants in the green community. The Madison Children’s Museum in Madison, WI developed a checklist for museum exhibit designers and fabricators to create exhibits that showcase best practices for a healthier environment. Exhibit SEED is a larger project funded by the National Science Foundation titled Sustainability: Promoting Sustainable Decision Making in Informal Education .
Some scholars suggest that sustainability and design are a natural extension of a museum’s mission statement . Some museums choose to make sustainability a part of their identity, writing their commitment to be green in their mission statements. Sustainability can be seen in the field of research, the purpose of public service, and the mandate for education. Museums that model green behavior enhance their missions and support their communities. 
Not all green museums feel sustainable directly with their missions. For example, an art museum that resides in a green building and can not consider its sustainable practices. 
As informational education centers that serve the public, museums are in a position to teach about sustainability to a wide audience in meaningful ways. Through a combination of motivation and information, Green museums lead by exhibition, programming, and websites. The goal is that they will learn about sustainable practices at the museum and then be able to implement them at home. 
Many museums dedicated to sustainability and conservation often use the works of theorists like Richard Louv and David Sobel to find the most effective ways to motivate their audiences to conservation action. For instance, Disney’s Animal Kingdom quotes Richard Louv’s Nature Deficit Disorder as one of their Kids‘ Discovery Clubs, which focuses on encouraging children to learn about what they can do to help wildlife.  Another museum to quote Louv’s Nature Deficiency Disorder for their programming is the North Carolina Museum of Natural Sciences. They spearheaded the national Take a Child Outside Week, which encourages children and adults to spend time together outdoors.  Many museums also approach sustainability issues with Ecophobia in mind. Ecophobia is David Sobel’s theory that if you do not know the facts, they will be able to learn more about the subject, they will retreat from nature.  An example of a museum attempting to overcome Ecophobia would be one of a number of initiatives that would have a positive impact on the environment. TeaBrooklyn Children’s Museums respects the developmental courses of children by using Their LEED certified building to teach children and Their families about environmental conservation through interactive exhibits and activities Appropriate age. 
In recent years, calls for museums To Become sustainable institutions-have come from dans le museum field as a way for museums to accomplish achieve social responsibility and civic engagement . Sustainability is an opportunity for thoughtful, proactive museum work. „Museums can play a critical role in moving communities to a more sustainable future.“ Aligning their missions and programs with sustainability principles … … will recalibrate their own daily practices as well as their community to the array of choices perhaps otherwise invisible to them „(183). 
Museums, as a trusted part of the informal education system, are able to address the economic, cultural, and social dimensions of sustainability.  They achieve this by engaging the public with interactive exhibits and by publicizing their own green efforts. The goal, stated or unstated, is to educate them about the effect they have on their environment, the ecological, economic, and social risks when they ignore their impact on the world, and they can reduce their carbon footprint. Thus, museums achieve civic engagement and social responsibility through teaching.
Some museums, such as the Royal Saskatchewan Museum in Saskatchewan, Canada, take a global approach to civic engagement. The Royal Saskatchewan Museum’s Green Exhibit is titled The Human Factor and Favors to show the human ecology impact on the planet, what practices they can adopt to this impact, and project what the future will be humans do not take action.  Visitors are helped to understand what Earth looks like before humans and the impact of time in the „Time Tunnel“.  The subsequent gallery, „Living Planet“, explains how global ecosystem functions and what is the Earth’s global ecosystem on a rotating globe. Specifically identified as a global population stress is the rising population. Curators placed in the exhibit in the world.  Beneath the clocks are the forms of humans and their shadow is the images of industrial productivity.  The following gallery, „Causes of Stress,“ identifies the source of ecological stresses as rampant consumerism and explains what causes this extreme behavior. The solutions gallery sustainable development and an electronic display of sustainability success stories. This is an effort to show bosses how their choices impact not only themselves and their parts of the world but other people and their environments. The last gallery, „Looking Ahead,“ describes the future of the world if humans adopt the prescribed changes.  The desired effect is an impact on the global ecosystem.
The Bronx Zoo seeks to educate its patrons about water resources and the impact of restroom use on water resources through the EcoRestroom exhibit. At the same time, by installing this restroom with composting toilets the Zoo has reduced its carbon footprint. The restroom serves men and women with 12 toilets and six sinks for women and two toilets, four waterless urinals and four sinks for men. The sinks do not rely on electricity or battery power; rather, they recharge as water runs through them. The used water runs into a Grey Water garden that is unharmed by the bio-compatible soap available for use by patrons. The restroom doubles as exhibition space, informing visitors of water conservation. Along the pathway to the entrance of the restroom there are water-droplet-shaped signs that give visitors tips for conserving and repurposing water at home. Signs continue over the sinks, providing visitors with facts about water use meant to inspire thought about their own use and what they can do to use less water. Signs on the inside of the stall doors inform visitors how composting toilets function and the impact they have on the environment. This installation not only shows patrons how they can make simple changes to conserve water but implements those changes in real time at the Zoo. In educating, the Zoo is also making a difference.
As stewards of the public trust, Museums bear a responsibility to maintain collections utilizing the most efficient methods available. Museums must do their part to ensure that there is a public to enjoy the collection and resources to exhibit the collection. One way museums can conserve resources is to incorporate energy saving practices into their daily operations, altering the facilities they already inhabit rather than building anew. Brophy and Wylie identify simple solutions such as installing motion sensors that turn the lights on when visitors enter the gallery and turn the lights off when they exit, such as those found at Colonial Williamsburg in Virginia. Those lightbulbs could even be replaced with long-lasting LED bulbs.Other museums that manipulate their facilities location include the Morgan Library, as identified by Brophy and Wylie, whose storage is „carved out of Manhattan bedrock.“ The bedrock provides natural cool storage without using electricity to generate an air conditioned climate. Thus neither money nor electricity are spent to control the climate of the storage space, which stresses not only museum funds but increasingly scarce electricity too.
Museums further achieve social responsibility by implementing the sustainable practices that they advocate in building or altering facilities such that they are sustainable.This includes using LEED building practices and sourcing materials locally. Purchasing building materials and employing local labor stimulates the economy in the vicinity of the museum. It also reduces the carbon footprint of construction; materials purchased from local suppliers do not need to be delivered on a tractor-trailer, on an airplane, or on a ship, all of which consume fuel, time and money. The Museum of Contemporary Art in Denver, CO, has incorporated locally sourcing materials into its LEED-Gold design plan. The Museum highlights that its green roof, furniture fixtures and equipment have all been locally sourced. The museum also encourages the use of public transportation by offering discounts to visitor who use this as a means of accessing the museum. In building to the LEED Gold standard, the Museum of Contemporary Art has also made its operations more energy efficient. The facade is built to maximize climate control and limit the use of traditional forced air. Radiant flooring circulates heat around the perimeter of the building. These are two ways that MCA Denver conserves energy. The Museum of Contemporary Art San Diego purchased paint, office furnishings, windows and doors from local vendors. By educating the community and putting advocacy into action, museums become socially responsible.
Landscapes and outdoor spaces
One approach green museums are taking care of their outdoor spaces and landscape design. Greening outdoor spaces provides multiple benefits beyond aesthetics and museums. According to the National Clearinghouse for Educational Facilities , there are many types of educational, recreational, and social skills that can be successfully taught outdoors. Outdoor museum spaces include pathways, trails, pavilions, picnic areas, fountains, courtyards, waste management areas, rooftops, and the greater surrounding environment. Whether a new facility or an existing one, green museums use these areas to implement sustainable practices. For instance, incorporating native plants, wetlands , bioswales , rain gardens , butterfly gardens, vegetable gardens, and green roofsThey are all ways museums, and their green grounds. Additionally, the natural surrounding environment can be an integral part of the green museum (where the land is part of the museum). Incorporating these outdoor spaces provides a more flexible learning environment with greater educational opportunities.  Outdoor spaces allow for hands-on projects that promote environmental awareness and are an ideal catalyst for community involvement. 
Increasingly, green museums are incorporating sustainable thinking in their outdoor planning. For example, the Peggy Notebaert Nature Museum designed a rooftop that won the 2003 Chicago Green Roof Award. The living portion of the roof reduces the volume of storms and solar panels.  The Pittsburgh Botanic Garden is working on a claim to heal its land that was once used for coal mining. The project allows the garden to tell a story of ecological change and the importance of restoration.  In the summertime, Walker Art Museum uses its outdoor space, Open FieldCollecting, recreation, relaxation, and exploration.  The Natural History Museum of Utah prides itself on being a model for environmental sustainability. The exterior of the facility is designed to respect and reflect the natural world by blending in with the surrounding environment. 
The ability to quantify the performance of outdoor spaces is important in the green museum community. There are multiple rating systems and is a growing consultancy field aiming at helping museums audit, develop baselines, and benchmark their performance.  One strategy for museums going green is to become LEED Certificated. In 2000, the US Green Building Council (USGBC) introduced the Leadership in Energy and Environmental Design (LEED) rating system that ranks sustainability in buildings and operations. To date, LEED is focused mainly on structures and development, while landscape issues are minimally addressed. The Sustainable SITES Initiative (SITES)The American Society of Landscape Architects , the Johnson Bird Wildflower Center and the United States Botanic Garden , have created a joint venture with the American Society of Landscape Architects . Modeled after the LEED program, site design, construction design, operations, maintenance and monitoring. Currently SITES is in the pilot phase, and will be completed in June 2012. In November 2009, SITES released „Guidelines and Performance Benchmarks 2009“ for the pilot projects which includes the rating system with five areas of focus; hydrology, soils, vegetation, materials, and human health and well-being. While LEED focuses on energy, the key to SITES is ecosystem services .
Ecosystem services are provided by natural ecosystems such as:
- Climate regulation
- Clean air, soil, water
- Water supply regulation
- Soil erosion / sediment control
- Habitat and pollination
- Decomposed waste integration
- Human health and well being
- Food and organic products
- Cultural, educational, and aesthetic value
- Flood impact mitigation, among others.
SITES shows that when assessing overall sustainability, the museum is also important to the building structure. However, like any operational decision, the appropriate sustainable design techniques must balance with the museum’s mission. It helps to articulate what learning outcomes are involved and what is the plan for the outdoor space.
Lighting in museums
Lighting is an essential component for museums, it is used for illuminate objects, offices, bathrooms, entrances, storage, and almost every other space in a museum. As important as light for a museum, some light can cause negative effects on objects such as paintings, textiles, leather, photographs, books and paper, or mounted specimens. Light damage is cumulative and irreversible, so museums must take special care to avoid unnecessary light damage. The spectrum of light is divided into three categories: ultraviolet light (UV) , visible light , and infrared light (IR) . Ultraviolet light is most damaging to objects, while infrared light produces heat which also causes damage. Museums use halogen goldmetal halide track lighting in galleries and fluorescent light in storage; however, these are not energy efficient options.  Halogen lights waste energy by creating the times of a regular incandescent light and can become fire hazards. In a world where the use of energy is more efficient, the museums have more opportunities than ever before.  The challenge to the lighting designer is to achieve a balance between creating and maintaining a safe environment. Lighting is a rapidly changing field, especially with new innovations in green technology and energy-efficient options. The lighting options for museums are now available in the next ten years.
Beyond halogen and incandescent light options, LEDs, CFLs, fiber optics, hybrid solar lighting and natural light.
- LEDs – LED stands for light emitting diodes which are illuminated by the movement of electrons in a semi-conductor material. LEDs consume a fifth of the energy of the incandescent and last one hundred times longer. While LEDs can be more expensive than incandescent, they use less energy and are more cost effective. LEDs produce no UV light, little heat, and can be used to illuminate objects. The US Department of Energy estimates that LED lighting over the next 20 years in the United States could save about $ 265 billion in energy costs.
- CFLs – Introduced in the 1980s, compact fluorescent light bulbs are used to produce electricity. CFLs use less energy than incandescent and last six to ten times longer. CFLs contain mercury so disposing of them can be very complicated. Museums need to have special disposal methods when using CFLs.
- Fiber Optics – Fiber Optic The heat source is removed from the end of the fiber and the longer the fiber, the more loss of heat at the end. Glass fibers dissipate UV light, plastic fiber need UV filtering.
- Hybrid Solar Lighting – Hybrid solar lighting combines solar power and fiber optics to channel sunlight into an enclosed space while directing infrared light into a concentrating thermo-photovoltaic cell that converts to electricity. Sunlight is tracked by a parabolic disk and the sensors maintain a constant level of illumination by supplementing sunlight with traditional electric light in special hybrid lighting fixtures. Hybrid solar lighting is more efficient than photo-voltaic cells.
- Natural Light – Numerous museums uses natural light instead of artificial light to illuminate spaces. However, sunlight can be the most damaging form of light because of the UV emitted. Should be considered in spaces that do not contain light sensitive materials: lobbies, offices; or in museums that do not contain light sensitive objects. Museums can also use UV filters to reduce the harmful effects of sunlight. One rationale for using natural light is predicated largely on economics; a greater reliance on daylight reduces energy consumption and costs. Recent studies provide more justification than natural light. With properly installed and maintained daylighting systems, natural light has been proven to be beneficial for the health, productivity, and safety of building occupants. 
- Sun breeze is a natural lighting option that uses permanent architectural sun-shading techniques to reduce the amount of light that enters a building or a museum.
- Motion Sensor and Task Lighting – Museums can use motion sensor or task lighting in areas with less traffic or office spaces. Lighting all areas that are used rarely or not at all high traffic spaces is a drain on energy and money for a museum. These lighting options can only be used when a person is in a certain area.
Greening the field of preventive conservation
The needs of conserving artifacts and landmark buildings are Often seen as conflicting with The Most efficient and effective means clustering of „going green.“  Light, temperature, humidity, pollutants, particulates, and pests must all be Monitored in order to properly preserve objects and historic buildings – the energy spent on control and maintain ideal environments for historic building and artifacts alone is staggering.  Since the heart of authenticity for many types of museums is the display of artifacts and specimens from their collections, it can be said that  For example, theCalifornia Academy of Sciences , which is housed in a LEED Platinum building designed by Renzo Piano , utilizes a natural ventilation system that could expose its collections to airborne flora and fauna, fluctuations in temperature and humidity, and strong daylight. Jonathan Katz, CEO of Cinnabar, Inc., has been hired by the California Academy of Sciences to design exhibits for the Natural History Building, a „kit of parts“ system where they could be configured to control temperature, humidity, and light. These cases had to reflect the sustainability mission of the museum and thus had to be built in such a way that they could be reconfigured and reused as exhibits changed. This is simply an example of how the perceived conflict between green and building design and the preservation of objects has been resolved.
The struggle to reconcile green practices and object conservation goes far beyond the exhibition hall, as well as in their collections. Museum conservators are tasked with the care, preservation, and restoration of these objects – the American Institute for Preservation , a professional organization in the United States that establishes and upholds professional standards among its members, states that the goal of its conservators is „to preserve the material evidence of our past so we can learn from it today and appreciate it in the future. “ In striving to be „greener,“ conservators must also „consider not only the interaction of materials and the environment with the art and artifacts [they] treat, but also the use, production, and disposal of the materials [they] employ in [ their work. “  Thus, another problem facing the conservatives is the issue of finding non-toxic or lower VOC replacements. In order to fully understand the challenges associated with green conservation practices, then, Patricia Silence, in „How Are US Conservators Going Green? Results of Polling AIC Members „identified five areas pertaining to sustainable practices: recycling, energy consumption, waste, improved sustainability through products and procedures, and education.  The following list is based on findings from Silence’s paper:
- Reusable materials (rags, sponges, brushes)
- Less paper (digital archives)
- Saving scrap (for later use)
- Temperature Control (radiant heating systems)
- RH Control
- Light Control (better lighting systems – better bulbs, utilizing natural light when possible, etc.)
- Using renewable energy to power
- Using more energy-efficient environmental systems
- Use less energy and materials (wood, paper, plastic, foam)
- Try to reuse or recycle a greater proportion of used items
- Proper disposal training for toxic items
Improved Sustainability through Products and Procedures
- Less toxic chemicals and solvents
- Water-based cleaning systems and / or natural products
- Organic cotton rags and towels
- Recycled or re-purposed products
- Used equipment, furniture, tools
- Less toxic packing materials
- Less toxic pest management chemicals
- Procedures for proper disposal
- Procedures for testing new materials
- Best Practices Manual
