Cropgen - AD project

>> Gate fees report from WRAP

Gate fees charged at composting and AD facilities in the UK have increased slightly over the previous twelve months, whilst the number of AD sites has doubled in the last 12 months.

>> EA release duly-making checklist for IED installations

The EA has released an IED duly-making checklist, which is a document that sets out what information is required in making an application for a â��newly prescribedâ�� installation activity.

>> Food waste feedstocks insufficient for new projects, report suggests

A report by consultancy Eunomia has found that there is a shortfall in the volume of food waste feedstocks required to fulfil the needs of AD plants currently in development

>> Identifying Best Practice for Silage Making for AD

Work is currently underway, to identify current knowledge of silage making in the UK and help determine best practice for silage making for AD. As part of this work, a survey has been created to obtain a better understanding of how silage making affects the quality of different crop silages and their subsequent biogas yields when used in anaerobic digestion.

>> WRAP video on using digestate as a renewable fertiliser

WRAP have launched a video that will help more farmers use anaerobic digestate as a renewable fertiliser. It provides practical advice for farmers and agronomists on how to maximise the supply of nutrients to crops, and how this can be balanced with standard fertilisers.

CROPGEN

CROPGEN was a research project funded by the EU's 6th Framework Programme, involving 11 partners in 6 European countries. The concept was based on the use of anaerobic digestion (AD) as a means of producing methane from biomass, including energy crops and agricultural residues. The technology of biochemical methane generation is well established: the research determined how the technology could best be applied to provide a versatile, low-cost, carbon-neutral biofuel in an environmentally sound and sustainable agricultural framework.

The project finished in July 2007.

Project outcomes:

Renewable energy from crops and agrowastes

Digestion and codigestion mass balance for different operative conditions and process configurations for oily crops and agricultural market wastes

Life cycle energy balances on a number of crop species

Database on the methane production potential from mixed digestion

Optimal pre-treatment methods to increase methane yields under various conditions

Standardised test procedures for assessing kinetic constants and evaluating reaction rates

Optimal storage systems for energy crops for various climatic conditions

Cost-benefit analysis to determine whether farm energy production can lead to measurable advantages in the longer term productivity cycle

Assessment of the potential for crop-derived biogas as an energy source in the EU, taking into account technical and environmental issues and socio-economic impact
