Waste heat to power

Client: EcoGenR8 Ltd
Location: n/a
Service division: Engineering
Sector: Power

Waste heat from industrial processes has a real value with an opportunity for revenue generation and carbon reduction. Many processes produce heat at temperatures and quantities where conversion to electricity is viable but the principal barrier to uptake is typically length of payback which can vary from 3 to 8 years.

EcoGenR8, of which AFECO is a trade name, were awarded a Technology Strategy Board (TSB) Smart Grant to carry out a market assessment investigating the recovery of low grade waste heat. Smart Grants are awarded to assist businesses to engage in research and development projects in strategically important areas to enable the successful emergence of new products, processes and services and EcoGenR8 were awarded the grant to assist in the development of their waste heat recovery business, which will be delivered through AFECO.

AFECO have used the grant, which was matched by our own funding, to determine whether energy recovery systems, such as Organic Rankine Cycle (ORC’s), can be successfully matched with industrial sources of low grade waste heat and to develop a business plan to roll out a successful heat to power business. The scope included:

  • Identification of technology solutions
  • Identification and prioritising of industrial applications
  • Development of a viable technical and commercial model for identifying suitable sites
  • Building a business case and funding structure for new investment into this market

Banbury STW food waste treatment

Client: EcoGenR8 Ltd
Location: London, UK
Service division: Engineering
Sector: Waste, Water, Power, Energy

EcoGenR8, together with planning advisors, GP Planning Limited, are working with Thames Water on proposals to build a renewable energy plant at Banbury sewage treatment works.

We propose to build an environmentally friendly treatment plant at the site. The plant would treat food waste, reducing the amount of food waste sent to landfill, and generate renewable energy.

A planning application was submitted on 2nd September 2013 and is available to be viewed on Oxfordshire County Council’s website.  Alternatively, copies of the application and supporting document are available below:

The planning application is due to be considered by the Planning & Regulation Committee on 2nd December 2013.

AFECO, as a trading name of EcoGenR8 Limited, have provided technical support in developing the application.

Food waste anaerobic digestion projects

Client: EcoGenR8 Ltd
Location: London, UK
Service division: Engineering
Sector: Waste; Water; Energy; Power

EcoGenR8 develops and manages waste treatment and renewable energy supplies in the UK with a primary focus on producing biogas through the anaerobic digestion of organic wastes. In 2011, EcoGenR8 were awarded a contract to develop a portfolio of energy from waste (food waste anaerobic digestion) projects with Thames Water, the UK’s largest water and sewerage company. Thames Water serve a population of 14 million across London and the Thames Valley including  an established network of over 30 anaerobic digestion sites.

Anaerobic digestion has been used to treat sewage sludge for many decades. As well as reducing pathogens in sludge, the process produces valuable biogas which is converted to electricity and heat through CHP (combined heat and power) engines, or upgraded to natural gas quality (biomethane) and injected directly into the gas grid.

EcoGenR8 partnered with Howard Tenens, a sustainable logistics company, to develop the Thames Water opportunity, the focus of which is to sweat existing assets and maximise synergies with current operations in order to develop a portfolio of sites that will have the capability to treat food waste and generate a combination of renewable electricity and biomethane. The project  incorporates detailed technical and commercial development, including:

  • Definition of the market potential
  • Development of technical and financial models
  • Identification of technology, waste, construction and operational partners
  • Planning and permitting applications
  • Securing contracts required for financing

AFECO are providing ongoing support to EcoGenR8 in developing the technical aspects of this project and in particular site investigations, technology evaluations and assessment of integration with existing assets.
