In 2017, Gloucestershire processed 35,000 tonnes of food and farm waste into biogas; the result generated 4.56 GWh of power for 1,400 homes at Rose Hill Recycling

In 2017, a recycling facility in Gloucestershire demonstrated how food and agricultural waste could become a valuable source of renewable energy rather than simply ending up as rubbish. Rose Hill Recycling, based in Dymock, was processing around 35,000 tonnes of food and farm waste each year when a new biogas-fired combined heat and power (CHP) plant was introduced. The facility was designed and managed by Veolia under a project announced in February 2017, with the CHP unit capable of generating 4.56 gigawatt-hours (GWh) of renewable electricity annually—enough, according to Veolia, to supply around 1,400 homes. The project offered a striking example of the circular economy in practice, turning organic waste into energy while reducing reliance on conventional electricity supplies.

The story began with a straightforward environmental challenge: what should happen to unavoidable food waste once it can no longer be eaten or reused? At Rose Hill Recycling, mixed food waste collected from across the Cotswolds became a feedstock for anaerobic digestion, a biological process that breaks down organic material in an oxygen-free environment.

Rather than treating food scraps and agricultural waste solely as something to dispose of, the facility treated them as a resource containing recoverable energy. Veolia said the Dymock site processed food and farm waste as part of Gloucestershire County Council's food waste recycling strategy. This approach connected local waste collection with renewable electricity generation, creating a system in which discarded organic material could contribute to the energy needs of nearby communities.


Anaerobic digestion is central to understanding how the Rose Hill system worked. During the process, microorganisms break down organic matter and produce biogas, a gas mixture that can be used as an energy source. At Rose Hill, the biogas produced from food waste, animal waste and energy crops was fed into the CHP system.

The CHP technology then produced electricity while also recovering useful heat. Veolia described the arrangement as a closed-loop energy solution because heat from the CHP process could support the anaerobic digestion operation, while the resulting biogas returned to the cogeneration unit. This integration helped the facility make productive use of both the organic material entering the site and the energy generated during its treatment.

The numbers illustrate the scale of the operation. Processing 35,000 tonnes of food and farm waste annually represented a substantial stream of organic material being diverted into a resource-recovery process. The new CHP plant had an electrical capacity of 520 kilowatts electric (kWe), while its projected annual electricity output was 4.56 GWh.

Veolia estimated that this amount would provide enough electricity for approximately 1,400 homes. Put another way, the project demonstrated that waste management infrastructure could serve an additional function beyond disposal and recycling: it could become part of local renewable energy infrastructure. The electricity generated was intended to reduce the site's demand on the local electricity grid, while the facility itself could become energy self-sufficient through renewable generation.

The environmental argument for the project was also closely connected to the problem of organic waste in landfill. When biodegradable material is buried under landfill conditions, it can generate methane as it decomposes. Capturing organic waste through anaerobic digestion provides a different pathway: instead of allowing the material to decompose uncontrolled in landfill, the process captures biogas and puts its energy content to productive use.

Veolia said the Rose Hill CHP project was expected to save approximately 1,750 tonnes of carbon dioxide emissions each year. The company's case study also says the facility's renewable heat and electricity generation reduced emissions and improved the site's carbon footprint. These figures were presented by Veolia in connection with the project and illustrate the environmental benefits the company associated with replacing conventional energy demand and landfill disposal with resource recovery.

Rose Hill also provides an example of why food-waste recycling can be more than a simple collection service. Once food waste has been separated from other household and commercial rubbish, it can enter treatment systems capable of recovering different forms of value. Anaerobic digestion can produce biogas for energy generation while also leaving behind digestate that can be managed as a separate material.

In this model, the concept of waste changes: something previously regarded as an unwanted end product becomes an input for another process. That principle lies at the heart of the circular economy, where resources are kept in productive use for as long as possible and waste is reduced through recovery, reuse and recycling. Rose Hill's operation showed how that concept could be applied at a regional scale.

The project was also part of a broader renewable-energy conversation taking place in Britain in 2017. Veolia said the Rose Hill CHP installation would contribute toward the then-government target of obtaining 20% of the UK's power from renewable sources by 2020. The company also noted that the project would add to its existing UK biogas electricity-generating capacity.

While the national energy landscape has changed substantially since 2017, the underlying principle demonstrated at Dymock remains relevant: renewable energy does not have to come exclusively from wind or solar installations. Biogas can provide another source of energy when organic materials such as food waste are collected, treated and managed effectively. The Rose Hill example therefore connected waste reduction, renewable electricity and local resource management in a single system.

The Rose Hill Recycling story ultimately shows how an everyday environmental problem can become an opportunity for resource recovery. In 2017, the Dymock facility was processing up to 35,000 tonnes of food and farm waste per year and using anaerobic digestion and CHP technology to transform organic material into renewable electricity and useful heat.

Its reported annual generation of 4.56 GWh was equivalent, according to Veolia, to the electricity needs of around 1,400 homes, while the project was expected to save about 1,750 tonnes of CO₂ emissions annually. More than a statistic about a recycling plant, the Gloucestershire project offered a tangible illustration of the circular economy: food waste could be collected locally, converted into biogas, used to generate energy and returned to the community as a useful resource.
