Composting
Composting is a natural process that involves breaking down organic materials, such as food scraps, yard waste, and other biodegradable materials, into a nutrient-rich soil amendment called compost. This process is facilitated by microorganisms, such as bacteria and fungi, which decompose the organic matter, turning it into a dark, crumbly substance known as compost. Composting also helps divert organic waste from landfills, reducing greenhouse gas emissions and contributing to a more sustainable waste management system.
Composting offers several benefits to schools:
- Educational opportunities: Composting provides hands-on learning experiences for students to understand the natural decomposition process, soil science, and environmental stewardship. It can be integrated into various subjects such as science, biology, and environmental studies, fostering environmental literacy and awareness.
- Waste reduction: Implementing composting programs in schools can significantly reduce the amount of organic waste sent to landfills. This reduces the school’s environmental impact, lowers waste management costs, and helps achieve sustainability goals.
- Resource conservation: Composting organic waste generates valuable compost, which can be used to enrich school gardens, landscaping, or green spaces. By closing the nutrient loop, schools can reduce the need for chemical fertilizers, conserve water, and improve soil health.
- Community engagement: Composting can bring together students, teachers, staff, and the broader community in a collaborative effort towards sustainability. Schools can involve parents, local businesses, and community organizations in composting initiatives, fostering a sense of environmental responsibility and community pride.
- Promotion of healthy eating habits: Composting encourages students to be mindful of food waste and can promote healthier eating habits by connecting them to the food production process. Students may become more aware of where their food comes from and the importance of reducing food waste.
- Environmental stewardship: By composting, schools demonstrate their commitment to environmental stewardship and sustainability, instilling values of conservation and responsibility in students. This can inspire future generations to become environmentally conscious citizens.
Overall, composting in schools provides numerous educational, environmental, and community benefits, making it a valuable practice for fostering sustainability and environmental awareness.
Waste Reduction Tools
Conducting a food waste audit involves systematically assessing and analyzing the amount and types of food waste generated in a specific location, such as a school. Here’s how it typically works:
- Collection: The first step is to collect all food waste generated over a predetermined period, such as a week or a month. This includes both pre-consumer waste (e.g., food scraps from food preparation) and post-consumer waste (e.g., uneaten food from plates).
- Sorting and categorization: Next, the collected food waste is sorted and categorized into different types of waste, such as fruits, vegetables, grains, dairy, meat, and leftovers. This helps identify which types of foods are being wasted the most.
- Weighing and measurement: The sorted food waste is then weighed to quantify the total amount of waste generated within the specified timeframe. This provides a clear understanding of the volume and weight of food waste produced.
- Analysis: Once the data is collected and sorted, it is analyzed to identify patterns, trends, and areas of waste generation. This analysis can reveal opportunities for waste reduction, such as adjusting purchasing practices, portion sizes, or menu planning.
- Reporting and recommendations: Finally, the findings of the food waste audit are compiled into a report that outlines the amount and types of food waste generated, as well as recommendations for reducing waste. These recommendations may include strategies such as composting, donation to food banks, share tables, implementing portion control measures, or improving food storage and handling practices.
Overall, conducting a food waste audit provides valuable insights into the sources and magnitude of food waste, helping organizations and individuals develop targeted strategies to reduce waste, save money, and minimize environmental impact.

What is a share table?
A share table in the National School Lunch Program is a designated area within a school cafeteria where students can place unopened, individually packaged food items that they choose not to eat or take home. These food items are typically items like whole fruits, packaged snacks, or unopened milk cartons.
