Welland Bio Power Resources Centre is a renewable power facility located at Theddingworth, Lutterworth. It recovers up to 9MW (net) of electricity from approximately 72,000 tonnes of waste wood per year using gasification technology.
There are 24 permanent jobs. Local goods and services providers are being used wherever possible. The facility generates sustainable clean electricity from renewable biomass sources which is exported directly to the local power grid, for local consumers.
Power generated from biomass is an important form of renewable of energy, helping to decarbonise the energy system by replacing fossil fuels. By using non-recyclable material for fuel, facilities such as Welland Bio Power Resources Centre, can also help reduce the amount of waste going to landfill.
The facility will process up to 72,000 tonnes of non-recyclable waste wood per year. It will accept grades A to C waste wood from the adjacent timber processing facility.
Grade A is ‘clean’ recycled wood produced from pallets and secondary manufacture.
Grade B may contain Grade A wood, together with other waste wood sourced from construction and demolition activities, waste transfer stations, civic amenity sites and the manufacture of furniture from solid wood.
Grade C is made up of reclaimed waste wood from discarded furniture and other wooden fixtures and fittings. It can include MDF and chipboard material as well as wood.The facility will not accept waste wood which is classified as hazardous.
The facility is a privately funded, joint venture.
There are several other facilities in the UK using the same or similar technology as Welland Bio Power Resources Centre.
The facility is owned by Welland Bio Power Limited.
Welland Operations Limited operate and maintain the facility.
Cobalt Energy Limited provides professional techno-commercial management services, working and interfacing with both Welland Operations and Welland Bio Power.
Welland Waste Management Limited supplies the fuel for the facility.
Nexterra Systems Corporation gasification technology is used at the facility. Nexterra is a global developer and supplier of gasification technology for Energy from Waste (EfW) plants.
Waste wood arrives from the adjacent timber processing facility run by Welland Waste Management Ltd.
The fuel is initially stored in the reception/storage areas before being placed on to the conveying system. The conveying system removes both ferrous and non-ferrous metals from the wood before it enters the four gasifiers.
Within the gasifiers, a fuel pile forms. The fuel moves through the progressive stages of gasification, that is, drying, pyrolysis, combustion, cracking and reduction. A tightly controlled amount of air (oxygen) is introduced via nozzles in the cones to enable controlled combustion. Syngas is extracted from the top of the gasifier and is combusted with combustion air (oxygen) in four oxidisers to generate steam, which is used to drive a turbine - this in turn drives an electrical generator to produce electricity.
Flue gases are treated to reduce nitrogen oxides (NOx), sulphur oxides (SOx) and heavy particulates, before exiting to the atmosphere via the stack. The stack emissions are monitored using a Continuous Emissions Monitoring System (CEMS) to ensure they are in accordance with the Environmental Permit conditions.
Bottom ash, fly ash and Air Pollution Control Residues (APCr) are conveyed away from the process.
The facility uses a small amount of natural gas to engage the start-up burners. Once the process is up to temperature, the start-up burners are disengaged and the process becomes self-sustainable.
The process produces minimal by-products. By-products include effluent water, incinerator bottom ash (IBA), Air Pollution Control Residues (APCr), fly ash and flue gases.
Effluent water is treated on site and reused where possible.
Incinerator bottom ash is disposed of by a licensed operator and may be utilised in aggregate production.
Air Pollution Control Residues and fly ash are treated at a licensed facility off-site.
Flue gases are treated to render them safe in accordance with the Environmental Permit conditions before they are released to the atmosphere via the facility stack.
The facility was commissioned in 2017 and will operate for 25 years.
The facility will operate 24 hours per day, 365 days per year, this includes both operation and maintenance.
Waste facilities are regulated by the Environment Agency through an Environmental Permit. The Environment Agency will check for compliance throughout the facility’s lifetime.
As part of the Environmental Permit application, an air quality assessment was undertaken. The assessment uses a dispersion model which sets out the area where emissions from a facility may come into contact with the environment.
This assessment then compares existing air quality in the dispersion area with the potential impact of the emissions from the facility. The dispersion modelling concluded that emissions from the plant would not significantly impact local air quality.
The stack emissions are monitored using a Continuous Emissions Monitoring System (CEMS) to ensure they are in accordance with the Environmental Permit conditions.
The majority of process emissions are composed of gases which are already present in the atmosphere:
- Oxygen
- Water vapour
- Carbon dioxide
- Nitrogen oxides
Trace amounts of:
- Carbon monoxide
- Very small amounts of dust
- Trace amounts of gaseous and vaporous organic substances, expressed as total organic carbon
- Trace amounts of sulphur dioxide and trioxide
- Trace amounts of hydrogen chloride
- Trace amounts of hydrogen fluoride
- Trace metals
- Very small amounts of dioxins and furans, which are virtually undetectable.
These emissions are all governed by the Industrial Emissions Directive (IED) and must be sampled and monitored. Results are recorded, controlled and audited under the Environmental Permit issued for the facility.

Industrial facilities undertaking specific types of activity are required to use best available technology (BAT) to reduce emissions to air, water and land. Best available technology (BAT) and operational standards are employed at the facility.
Any emission breaches will be dealt with immediately, by means of process control or facility shutdown and reported to the Environment Agency.
Under normal operational conditions there will be a minimal visible plume from the stack. The plume may be more visible at close proximity to the stack output, depending on atmospheric conditions.
The facility must comply with all issued permits and consents, which in turn are issued in accordance with current legislation.
Welland Operations uses an integrated business management system (IBMS) which consists of policies, processes, and procedures, written to conform to all issued consents.

All emissions will be sampled and monitored (using accredited and calibrated equipment, including off site laboratories), recorded, controlled, and audited under the Environmental Permit issued for the facility.
The key regulators for the Facility are:The Local Authority (LA) – Leicestershire County CouncilEnvironment Agency (EA)Health and Safety Executive (HSE).
As part of the Environmental Permit application, a noise assessment was conducted. This noise assessment establishes the baseline noise levels in the locality of the nearest receptors and sets an acceptable noise level for the facility. The facility has been designed to comply with this acceptable noise level during full operation.

There is no scientific evidence to support this. Research studies conducted and published to date have concluded that there is no conclusive link between such facilities’ activities and public health issues in the surrounding localities.
Much detailed research has been completed and published by public and private organisations in the UK and across the world.
The research that has been conducted and published to date has concluded that there is no conclusive link between such facilities’ activities and public health issues in the surrounding localities.
One of the most recent studies was conducted by the Small Area Health Statistics Unit at Imperial College London funded by Public Health England and the Scottish Government. This looked at Municipal Waste Incinerators (MWI)s at 22 sites across the UK between 2003 and 2010 and the effect on infant mortality or reduced foetal growth in the localities.
The facility’s effluent water is treated and reused where possible. Excess waste water is treated and transferred to the facility’s attenuation lagoon, before being released into the River Welland in accordance with the Environmental Permit conditions set by the Environment Agency.
