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.

TSB awards funding for pasteurisation process

EcoGenR8, a developer of waste treatment and renewable energy supplies providing robust yet innovative solutions to the water and waste sectors in the UK, has received funding to optimise their proprietary pasteurisation process.

The funding has been awarded by the Technology Strategy Board (TSB) which is a business-focused organisation dedicated to promoting technology-enabled innovation across the UK and is intended to enable the rapid, effective and sustainable application of technology.

EcoGenR8 have developed an energy optimised pasteurisation system that ensures regulatory compliance whilst maximising net energy production when combined with anaerobic digestion for the biosolids and biowaste industries. The system is designed to balance cost, energy efficiency and digester performance to maximise the end-to-end process performance. The funding will allow EcoGenR8 to further optimise the design and maximise heat transfer and hence overall energy efficiency and provide independent validation of the improved technology design, ensuring it is ready for full-scale market applications.

Pilmico pig farm anaerobic digestion


Client: Pilmico Animal Nutrition Corporation
Location: Tarlac, Philippines
Service division: Optimisation, Engineering
Sector: Waste, Water


Pilmico Animal Nutrition Corporation own and operate a number of pig farms including a farm in the province of Tarlac in the Philippines which treats its own wastewater and slurry in dedicated anaerobic digester (AD) lagoons and uses the biogas produced by the process to generate electricity for use on-site. Since installation and commissioning, the performance of the AD and generating engines at one of the farms has been less than that anticipated by the design and Pilmico were keen to identify the reasons behind the underperformance and understand what measures, if any, could be taken to improve the situation.

AFECO were appointed to undertake a review of the pig farm operational practises, asset configuration, AD performance and generating engines to assess where possible improvements could be made and highlight any reasons for the underperformance. AF ECO carried out a site visit to the farm and used this visit together with background design information and operational data to fully analyse the plant performance. A process model of the site was composed and used to assess actual performance data and the original design data against the theoretical performance. The modelling highlighted that the original design significantly over-estimated the expected biogas production and that the current biogas production was, in fact, well in line with the theoretical expectations. As a result the generating engines were also over-rated and the down-turn required reduced the engine efficiency. A review of the engine specification also revealed their unsuitability to operate on biogas which potentially lowered the efficiencies even further.

The review highlighted a number of potential improvements that could be implemented to enhance the system performance. These improvements included modifications to the condensate trap to remove the moisture present in the biogas prior to entering the engines, improving their efficiency, and improvements to the existing sand/grit trap prior to the AD lagoon. A conceptual design and CAD drawings for the condensate trap and sand trap modifications were produced to accompany the report.

In summary, the review undertaken by AFECO avoided the need for costly modification works to the pig farm AD plant by demonstrating that the digester performance was in line with expectations and operational staff were carrying out their role effectively. The plant modifications recommended were simple and cost effective with the impact of sustaining the long term performance of the plant.
