ENVIRONMENTAL PRINCIPLES CHARTER FOR THE 21ST. CENTURY • Develop and operate facilities and undertake activities with energy efficiency, sustainable use of renewable resources and waste generation in mind. • Conduct or support research on the impact and ways to minimize the impacts of raw materials, products or processes, emissions and wastes. • Modify the manufacture, marketing, or use of products and services so as to prevent serious or irreversible environmental damage. Develop and provide products and services that do not harm the environment. • Contribute to the transfer of environmentally sound technology and management methods. C& E News, April 8, 1991, pg. 4 CHEMICAL INDUSTRY’S RESPONSIBLE CARE PROGRAM

BIOBASED PRODUCT DRIVERS -- U.S. GOVERNMENT • Presidential Executive Order 13101 (Greening the Government Through Waste Prevention, Recycling, and Federal Acquisition, dated September 14, 1998) • U.S. Department of Agriculture (USDA) is proposing guidelines for listing commercially available biobased products for purchase by Federal agencies. • Biobased product is defined as a commercial or industrial product (other than food or feed) that utilizes biological products or renewable domestic agricultural (plant, animal, and marine) or forestry materials. • USDA is listing only those products which are considered by USDA to be within the U.S. Environmental Protection Agency (EPA) Environmentally Preferable Products Guidelines. • U.S. EPA has issued “Guiding Principles” for products to be listed as “Environmentally Preferable”. Recycling, and the use of recycled products is on the top of the list of these principles. • Composting is Biological (Organic) Recycling
BIOBASED PRODUCT DRIVERS -- U.S. GOVERNMENT (Contd.) The requirement for Federal agencies to consider biobased products which is environmentally preferable (U.S. EPA) is also in Office of Management and Budget (OMB)/Office of Federal Procurement Policy (OFPP) Policy Letter 92‑4 and applies to all Federal agencies.

Toward a More Sustainable Campus at Michigan State University University Committee for a Sustainable Campus
University Committee for a Sustainable Campus In September 1998, the Executive Committee of Academic Council Approved an Initiative to Further the Efforts of Michigan State University Towards Becoming a More Sustainable Campus.
Developing an Infrastructure • The proposal for a university wide committee aimed to create a committee with wide representation from throughout the campus and across all lines of employment and study. • The proposal allowed for participation of operations staff from various units across campus, a faculty member from each college and two graduate and two undergraduate students. • Through nominations and appointments a committee was formed and met initially at the end of January 1999. • The committee elected a chair, discussed committee processes and worked in tandem with the seminar series steering committee to ensure the series success.
Mission Statement In keeping with MSU’s role as a land grant university, the mission of the University Committee for a Sustainable Campus is to foster a collaborative learning culture that will: • Lead the Michigan State University community to a heightened awareness of its environmental impact • Conserve natural resources for future generations • Establish MSU as a working model for creating a sustainable community We envision a sustainable community as one that provides for the social and economic needs of all its members for many generations to come, without compromising the health of the biosphere
Goals • Education- to heighten the environmental awareness of the Campus • Research- to increase research on our campus environmental impact and support environmentally focused research by the campus community. • Support - to build support throughout the campus to meet the mission of the university committee for a sustainable campus. • Outreach- to transfer knowledge of sustainability gained from MSU experiences beyond the campus. • Assessment - to coordinate an environmental assessment of the MSU campus. • Policy- to recommend adoption of policies which support the practice of environmental stewardship.

SUSTAINABLE AGRICULTURE • Crop yields on severely eroded soil are lower than those on protected soils because erosion reduces soil fertility and water availability • Corn yields on some severely eroded soils have been reduced by 12 to 21% in Kentucky, 0 to 24% in Illinois and Indiana, 25 to 65% in the southern Piedmont (Georgia), and 21% in Michigan. • During a single growing season, a hectare of corn (yield, 7000 kg/ha) transpires about 4,000,000 liters of water, and an additional 2,000,000 liters ha concurrently evaporate from the soil • In the United States an estimated 4 billion tons of soil and 130 billion tons of water are lost from the 160 million ha of cropland each year. This translates into an on-site economic loss of more than $27 billion each year, of which $20 billion is for replacement of nutrients and $7 billion for lost water and soil depth.
COMPOSTING & THE ENVIRONMENT • COMPOSTING IS AN ECOLOGICALLY AND ENVIRONMENTALLY SOUND APPROACH TO TRANSFERRING BIODEGRADABLE WASTE (INCLUDES THE BIODEGRADABLE PLASTICS) TO USEFUL PRODUCT • COMPOSTING IS BIOLOGICAL RECYCLING OF CARBON • COMPOST USE REDUCES CHEMICAL INPUTS, SUPRESSES CROP DISEASES, REPLENISHES ORGANIC CARBON, INCREASES WATER & NUTRIENT RETENTION, IMPROVES SOIL PRODUCTIVITY • “SUSTAINABLE AGRICULTURE” SCIENCE & ENGINEERING OF COMPOSTING, HOITNIK & KEENER, EDS. 1993 Narayan -- Biodegradation of polymeric materials during composting, p. 339
