Home Composting: Your Personal Contribution to Dining Sustainability

Colleges compost dining-hall waste at scale. You can close the loop at home—turning plate scrapings into garden gold, shrinking landfill methane, and building soil health.

Why It Matters

• Food waste = 30–40% of US food supply (USDA).
• Landfill food → anaerobic → methane (28× CO₂ potency).
• Compost → aerobic → CO₂ + stable carbon in soil.
• Home compost = zero transport emissions.

Modern Gear Makes It Easy

• Countertop collectors: Ceramic, stainless, bamboo—charcoal filters = no smell.
• Tumblers: Rodent-proof, fast, backyard-friendly.
• Worm bins: Indoor, year-round, great for kids.
• Bokashi: Ferments ALL food (meat, dairy, citrus); bury pre-compost.

Simple Daily Habit

1. Scrape plates into collector (not trash).
2. Empty to outdoor system 1–2×/week.
3. Balance with browns (shredded paper, leaves).
4. Turn/tumble on schedule.
5. Harvest finished compost 2–4×/year.

What Goes In (Most Systems)

• Fruit/veg scraps, peels, pits
• Coffee grounds, tea bags
• Eggshells (crushed)
• Grains, bread, pasta (moderation)
• Paper napkins, towels (unbleached)
• NO meat, bones, dairy, oils (unless Bokashi)

Non-Food Additions

• Hamster/guinea pig bedding
• Dryer lint (natural fiber)
• Shredded paper, cardboard
• Hair, nail clippings

Using Your Compost

• Vegetable/flower beds
• Container gardens
• Lawn top-dressing
• Houseplants
• Share/sell excess

Scale Perspective

One household composting 10 lbs/week = 520 lbs/year diverted. 1,000 households = 260 tons. Your bin is a node in a distributed solution.

Start with a $20 countertop pail. The habit forms in days. The impact compounds for decades.
