Composting 101

Why You Should Care About Compost

Laken Scott

What is compost? 

Compost is “the controlled aerobic, biological decomposition of biodegradable materials.” [1] 

Compost is also known as “black gold,” because it becomes a nutrient-rich fertilizer. [2] It retains soil nutrients, attracts beneficial organisms, and helps prevent soil erosion. [3] 

Why should I care? 

When organic waste breaks down in landfills, it creates methane. [4] Methane is more potent than carbon dioxide, with “80 times the warming power.” [5] 

25% of global warming is due to methane generation from human actions. [6] The Environmental Defense Fund says we're in a methane moment. “Atmospheric concentration of methane is increasing faster.” [7] John Kerry, a U.S. climate representative, tweeted that reducing methane is “the single most effective strategy to reduce global warming in the near term.” [8] 

What can I do? 

Here are a few actionable ways to lower methane emissions: 


DM @wwusustainability on Instagram and get your own composting bucket. Collect your fruit and veggie scraps, egg shells, tea bags, and coffee grounds. Then we’ll compost it for you! (Please take off all stickers - they aren’t compostable!) We compost Sundays at 9 a.m. If you want to get involved in the composting process, mention it in your DM. We’d love to have you! 

2. Store Food Properly 

Avoid throwing food away. Save your wallet and reduce methane. [9] 

3. Eat Until You’re 80% Full 

It’s good for your health, but also, overeating is food waste. It may not produce methane in landfills, but it’s not good for your body or the environment. [10] 

4. Tray vs. Plate 

The bigger the platter, the more space you try to fill. Try not to eat with your eyes in order to cut down on food waste.
