What is a materials exchangeA network that seeks to identify users for waste materials and products discarded by others; matches needs and provides referrals. program?
Materials exchange promotes the reuseProducts or materials that, after serving their original function, can be used again in their present form; some are designed to be reused repeatedly, while others not specifically designed for reuse are creatively used to fill a need. of items that are usable in their current condition, but might otherwise be thrown away. Through the Minnesota Materials Exchange Alliance, organizations such as state and local governments, schools, and nonprofit groups can be connected at no charge with those who have usable goods to donate.
Examples of materials that have been exchanged include: used office furniture, pallets, packaging materials, cleaning supplies, building materials, and paint. A current list of materials that are available can be viewed on the Internet at www.mnexchange.org. Or, for a free catalog, contact the Minnesota Technical Assistance Program at 612/624-1300 (toll free 800/247-0015) or the local exchange service in your area (see list at bottom of page).
What is the benefit of using a materials exchange program?
Using materials exchange programs can save you money. How? When you receive items through the exchange, they are often free or available at a very low cost. In addition to the monetary benefits, reusing items helps conserve resources and landfill space.

Using the Symbols
Less HazardousProducts containing hazardous chemicals can pose health risks to employees and the public, as well as threaten the environment. In addition, hazardous products often require special and costly waste disposal methods. Buy products that are labeled with none of the following signal words or those with the lowest level of hazard possible (but that still get the job done).
- Caution: mild to moderate hazard
- Warning: moderate hazard
- Danger: corrosive, extremely flammable, or highly toxic
- Poison: highly toxic
If less-hazardous alternatives are not readily available, use the least amount of a hazardous product needed to accomplish a task. Use up all of the product before throwing the container or packaging away.
Conserves EnergyReducing energy use is important because most energy production contributes to problems such as carbon dioxide emissions (tied to global warming), mercury releases, acid rain, volatile organic compounds, and nuclear waste. The U.S. Environmental Protection Agency and U.S. Department of Energy developed the Energy Star label to help purchasers identify energy-efficient products. These products reduce utility bills and help the environment.
Recycled ContentRecycled-content products save energy and resources, while also keeping waste out of landfills and incinerators. Recycled-content products can be made with post-consumer content, pre-consumer content, or a mix of both. Products made with post-consumer recycled content support our recycling programs at home and at work. If people do not buy products with post-consumer recycled content, manufacturers will no longer want the paper, cans, glass, or plastic we separate from trash. Pre-consumer content comes primarily from manufacturer scrap, and as such does not directly support such recycling efforts.
Prevents WasteMinnesota generates over 5 million tons of municipal solid waste annually, and this amount is increasing every year. Much of this waste comes from disposable and over-packaged products. Preventing waste can conserve natural resources and avoid the need to build new, expensive waste disposal facilities. You prevent waste when:
- Reducing the amount of material you buy to accomplish any task;
- Reusing a product in its original form; or
- Using repairable, refillable, or durable products.
Low Volatile Organic Compounds (VOCs)VOCs evaporate ("volatilize") easily at room temperature and often have a sharp smell. They are contained in many products, such as office equipment, adhesives, carpeting, upholstery, manufactured wood products, paints, solvents, pesticides, and cleaning products. Some VOCs can cause cancer in certain situations, especially when they are concentrated indoors. When VOCs hit sunlight, they create ozone, an air pollutant harmful to both people and plants. Many low-VOC versions of products reduce risks to human health and the environment.
Conserves WaterLess than 1% of the Earth's water is available for human consumption. There is no "new" water on Earth. Dry spells have reminded us that our water supply can be threatened - even in the Land of 10,000 Lakes - resulting in watering bans in some municipalities. Choosing products and services that conserve water, such as automatic flushers and low-flow faucets and toilets, can conserve this vital resource while reducing water and sewer bills.
End of Life ManagementWhat happens to a product after we use it? Some materials cannot go in the trash because they are hazardous in some way and therefore need separate - and sometimes expensive - special management. Some products are more easily recycled than others that do the same job. Making wiser buying choices can prevent a disposal concern at the end of a product's useful life, keep hazardous materials out of the environment, and expand options for recycling and reuse.
