Food waste is an environmental issue on all scales. Various universities within the US have begun implementing food waste programs, but our project is to make composting a nationally mandated program for all colleges. To implement this nationally, our number one goal is to create a Federal food waste management policy. To accomplish this, we must additionally establish committees at each university.
About one third of the food produced for human consumption is currently wasted at the global scale (FAO, 2011).
Food waste in the United States is a significant issue. An estimated 30-40% of our foods go uneaten. College campuses make up for a lot of these numbers.
Grand Valley State University has taken positive strides toward composting. GVSU has a "green team," 25 students whose responsibility is to educate students about their food waste. The student agriculture project also has composting, and does their part in educating those who visit more about food accessibility.
Nationwide, 22 million pounds of waste is contributed by food annually on college campuses (Hutchinson, 2023). The United States as whole throws out about $165 billion in food waste. Overall, about 30-40% of food is not eaten and goes to waste (Flynn, 2022). At the same time many people go hungry throughout the United States or lack access to fresh food and proper nutrition. Here lies many issues on all scales, economic, environmental, and social. This being said, as a country especially on college campuses, we are not working sustainably when it comes to our food and the waste it contributes.
Many colleges and universities use a buffet style in their dining halls. This can contribute to students taking more than they need or than they will eat. The food that is then left over is thrown into the garbage and sent to landfills which contributes negatively to the environment. Not only does the food emit methane as it sits in landfills, but also contributes to CO2 emissions that are wasted that were used to contribute to the production of the food, transportation, as well as the storage that was required to keep the food (Buzby, 2022).
“EPA estimated that each year, U.S. food loss and waste embodies 170 million metric tons of carbon dioxide equivalent (million MTCO2e) GHG emissions (excluding landfill emissions) – equal to the annual CO2 emissions of 42 coal-fired power plants. This estimate does not include the significant methane emissions from food waste rotting in landfills (Buzby, 2022).” Many people do not realize the effects that negatively impact the environment when it comes to wasted food. The lack of education contributes to the influence of waste, simply due to the fact there is a lack of understanding. By adding composting programs into all college campuses, a huge positive outcome could be made in all aspects of the sustainability hierarchy. Many individuals would also learn more on the topic of waste management and bring these practices into their lives post college.
Food waste within landfills generates large amounts of methane, a greenhouse gas up to 25 times more powerful than CO2.
Producing food that ultimately goes uneaten wastes water, energy, and land resources that could have been used more sustainably.
Composting converts food waste into nutrient-rich soil that can be used for campus gardens.
The food waste in the US is so high that the EPA estimates our emissions to be equivalent to a staggering 42 coal-fired power plants every year.
Composting saves colleges money by reducing landfill costs.
1.) Federal Policy Development...
Draft a national food waste management policy - partner with agencies, such as UDSA and EPA to establish composting as a mandatory practice for colleges and universities.
Legislation - pass a national bill to require food waste diversion.
Funding and Grants - to help colleges transition to composting infrastructure.
2.) Campus Level Implementation...
Committees - require all college campuses to form a committee to oversee compost and practices.
Communicate with cafeteria services - work with cafeterias to implement waste tracking.
3.) Student and Staff...
Education - implement, composting groups and activities for the campus to learn more about composting.
Clubs & Sports - Encourage students who are part of clubs and sports to take part in campus composting.
4.) Measure Efforts and Sustainability...
Waste reduction - require universities to report annual food waste rates along with composting success, or failure.
Improve - students and staff feedback will ensure continued success.
Expansion - As time goes on campuses can expand to large-scale composting.
Creating a timeline for our project was crucial to ensure a nation wide composting policy can be accomplished. We have 5 stages split up in years, each with brief bullet points on what we hope to accomplish
Implementing composting on campuses opens employment opportunities, as well as community engagement with students and neighboring organizations
Through composting, the universities will be reducing landfill costs, garbage pickup fees, and less money on fertilizers.
Composting would reduce the university's carbon footprint as less methane would be produced. Additionally, composting reduces the need for chemical fertilizers, a harmful substance that negatively impacts the environment.
When it comes to the budgeting of large scale projects such as creating a composting program in a college or university, there are a few different things that have to be taken into account. These things include the scale of the project/ how large of a population will be utilizing, materials that will be needed, staffing, educational tools, as well as the hauling that will be required to manage the compost.
In order to have composting within a college there will need to be several bins to collect the waste. The amount will depend on the student population as well as how many areas that are used for meal times. Bins used for composting generally cost about $500.
Staff is also required in order to have a composting program. This could be a great opportunity for student employment opportunities, but some schools may outsource their staff. If student workers are utilized each worker would probably be paid between $12.50-$15 an hour. The amount of labor would be determined by the size of the program. Anywhere from $1,000- $3,000 worth of labor a week.
Education is also a very important part of implementing a composting program anywhere. Many people do not really understand the segregation of waste material and how to know which items go where. Money would need to be put into educational materials, whether that be signage, videos, or a lecture of some type. This can range anywhere from $100-$500.
Lastly, a very important part of budgeting any type of waste management is the costs that go into the transporting of the materials. Some schools may sell their compost to local farmers, whereas others such as schools like Grand Valley, may utilize the compost themselves. Regardless the compost needs to be transported from where it is collected to where it will be utilized. Each pick up and processing fee can cost anywhere from $300-$400 a week. Each ton costing about $31.
The Federal Government at this time is doing severe budget cuts at an attempt to reduce national debt, and lowering interest rates. The sector that covers "Natural resources and environment" category is ranked the lowest percentage for current government funding. It is an applicable assumption to assume the government wouldn't be willing to fund towards this nation-wide project.
