Managing Food Waste Across Multiple Sites: 3R Urban Solutions UK on the Decentralised Composting Model

Decentralised on-site commercial composting model is the need of the hour for all businesses

**3R Urban Solutions UK** sets out the operational and financial case for multi-site businesses — hotel groups, pub chains, school trusts and NHS Trusts — to adopt a decentralised on-site composting model rather than managing food waste through a single centralised collection contract.

For businesses operating across multiple sites — a hotel group with ten properties, a multi-academy trust with eight schools, or an NHS Trust with three hospital campuses — food waste management under Simpler Recycling 2025 presents a particular challenge. Managing compliance centrally through a single collection contract sounds simpler but frequently delivers worse outcomes financially and operationally than a decentralised, site-by-site on-site composting model.

Mohit, Sales Head UK & Europe at 3R Urban Solutions UK, said the multi-site question is one he is increasingly asked to address. “The assumption most group operations managers make is that a single contractor covering all sites is the most efficient solution. But when you run the numbers site by site, the decentralised model almost always wins on cost — and it gives each site manager direct control over their compliance rather than dependency on a contractor’s schedule,” he said.

The financial argument for decentralisation is driven by collection logistics. A food waste collection contractor charges not just for the waste collected but for the vehicle time, fuel and driver cost of reaching each site. For a hotel group with properties spread across different regions, these per-collection logistics costs can represent 40–60% of the total contract value. An ***on-site composting machine*** at each property eliminates the logistics cost entirely — the machine is on-site, processes waste overnight, and requires no collection vehicle.

For multi-academy trusts, the model has an additional benefit. Each school generates a relatively modest volume of food waste — typically 25–75 kg per day — that can be handled by the S-25, S-50 or S-75 models. Installing one machine per school means each site is independently compliant, independently generating compost for its own grounds, and independently producing the food waste data needed for the trust’s sustainability reporting.

For NHS Trusts managing multiple hospital sites, the appropriate model depends on site geography. Where hospital campuses are close, a single high-capacity machine at the central catering hub may be appropriate. Where sites are geographically spread, individual site machines in the S-250 to S-1000 capacity range provide greater operational resilience.

3R Urban Solutions UK offers group procurement assessments for multi-site operators, including site-by-site capacity analysis, consolidated financial modelling and phased installation planning. The company manufactures and supplies the full Schnell Komposter range from 25 kg per day to 2,000 kg per day
