Calculate how much money you save by composting organic waste instead of sending it to landfill. Includes disposal cost savings and compost value.
Composting diverts organic waste from landfill, saving disposal fees and producing valuable compost. For businesses, where disposal costs can reach $50–100+ per ton, diverting food waste and organics to composting can generate significant savings. Households also benefit by reducing trash volume and creating free soil amendment.
Landfill disposal fees average $50–80 per ton in the US, with some regions exceeding $100. Composting costs $30–60 per ton through commercial haulers, or essentially free for backyard composting. The cost difference plus the value of finished compost (worth $20–40 per cubic yard) makes composting financially attractive in most scenarios.
This calculator estimates your annual savings from composting based on the amount of organic waste diverted, local disposal costs, and the value of the compost produced.
Integrating this calculation into regular energy reviews ensures that conservation strategies are grounded in measured data rather than assumptions about building performance and usage patterns. Precise measurement of this value supports sustainable energy planning and helps organizations reduce their environmental impact while maintaining operational performance and comfort levels.
Composting often costs less than landfill disposal, especially when you factor in the value of the compost produced. This calculator quantifies the savings to justify starting or expanding a composting program. Precise quantification supports regulatory compliance and sustainability reporting, ensuring that energy data meets the standards required by auditors and industry certification bodies.
Annual Savings = (Organic Tons × Landfill Rate) − (Organic Tons × Compost Rate) + (Compost Value)
Result: $93/year savings
Annual organics = 100 lbs/week × 52 = 5,200 lbs = 2.6 tons. Landfill cost saved = 2.6 × $70 = $182. Composting cost = 2.6 × $40 = $104. Compost value = ~0.87 tons finished compost × $30 = $26. Net savings = $182 − $104 + $26 = $104/year.
For restaurants and food service businesses, food waste comprises 50–70% of total waste. Diverting this to composting can reduce disposal costs by 30–50%. Some municipalities mandate commercial food waste composting, making it a compliance issue as well as a financial opportunity.
A backyard compost bin costs $30–100 and handles 200–400 lbs of organics per year. At $70/ton landfill cost, that saves $7–14 per year in disposal. But the real value is the 1–2 cubic yards of finished compost — worth $40–80 if purchased commercially.
Organic waste in landfills generates methane, a greenhouse gas 80× more potent than CO2 over 20 years. Composting converts the same waste aerobically, producing CO2 and beneficial humus. Diverting one ton of food waste from landfill prevents approximately 0.5 tons of CO2-equivalent emissions.
Backyard composting is essentially free after the initial bin ($30–100). Commercial composting services cost $30–60 per ton, which is typically cheaper than landfill disposal ($50–100+ per ton).
Approximately 30–40% of household waste is organic material that could be composted. For restaurants and food businesses, this can exceed 60%. Diverting organics dramatically reduces trash volume and disposal cost.
Composting reduces volume by 50–60%. One ton of organic waste produces approximately 0.5–0.7 cubic yards of finished compost. The exact amount depends on the feedstock mix and composting method.
Yes, especially if your municipality charges by volume or weight. Composting can reduce your trash by 25–35%, potentially lowering to a smaller (cheaper) trash bin. The free compost for gardens is a bonus.
A properly managed compost bin has minimal odor. Layer greens (food scraps) with browns (leaves, cardboard) at a 1:3 ratio. Keep the pile moist but not wet. A sealed bin prevents pest access.
Yes. Vermicomposting (worm bins) works indoors and handles 3–5 lbs of food scraps per week for a small household. Many cities also offer curbside organics collection or community composting drop-offs.
