Towards decentralized biogas generation: building community scale biogas reactors

This paper describes effort on the newly funded British Council project “Community Scale, decentralised Anaerobic Digestion for energy and resource recovery”. The aim of the project is to establish a network of small, community scale digesters both in Thailand and UK, for decentralised biogas generation from locally available wastes. We are especially focusing on food waste. The pilot digesters are paired with instruments for remote autonomous monitoring of biogas quality and conditions within the reactor (pressure, humidity). The data from networked reactors are collected on a single web portal, enabling remote monitoring. This reduces the need for trained personnel to be present at all times at each site. Reactor design is also described and the potential benefits and challenges are discussed

Providing energy for rural Indian communities: anaerobic digestion at Loughborough University

Rural Hybrid Energy Enterprise Systems (RHEES) is a research partnership between 6 UK and 7 Indian Universities. The aim of this project is to develop best practise at a smaller community scale which makes use of hybrid and combinations of biofuels. The idea is to improve rural energy availability, equity of cost and to generate an economic stimulus from the desire to provide greater energy security and reduced environmental impact. The Loughborough University part of the project is on how to apply village scale anaerobic digestion. This will be achieved by: Development of small-medium scale systems Combining solar/ thermal heat integration for pre-treatment of feedstock and pasteurisation of digestate Designing prefabricated systems Development of remote monitoring of digesters Working with partners and stakeholders throughout

The impact of plastic bag residues on anaerobic digestion performance

Aim of the research: To test the suitability of a plastic bag material for separate collection of food waste prior to AD. Toxicity, biodegradability and biogas production of the polymer was assessed by comparison with other feedstocks as controls. 10 litre digesters were used with and without pretreatment of the plastic. Short summary: In this work we used 10 litre digesters to investigate the suitability of a polymer material for food waste collection plastic bags. The material needed to be robust, but also biodegradable. Digestion of the synthetic polymer was compared to natural polymers from maize and rice. Two controls were also used: cellulose (known for its high biodegradability) and sewage sludge (the most commonly used AD substrate). Parameters checked daily, included gas production and composition, CST and total and volatile solids of the digestate. Stability was assessed by Ripley’s ratio, VFA, ammonia and pH. Digester loading was 1.36 g VS/l/day at 60 day HRT. The experiment was in two halves with sewage sludge feed in the middle, as an internal control to check activity. In a second experiment the material was pre-treated according to the Animal By-product Regulations (Regulation, 2011) heating to 70oC for 1hr. The results show the material was completely inert
