Monitoring bioaerosol and odour emissions from composting facilities – Defra

A significant part of government policy for waste management is focussed on diverting biodegradable waste from landfill.

The lowest cost alternative to landfill is open-air windrow composting (up to 2.5 m high rows of biodegradable waste in the open). The number of large composting sites in the UK has more than tripled in recent years to over 200.

Composting processes release bioaerosols, which are composed of fungal spores, live bacteria, allergens and respiratory sensitisers and can be harmful to humans and other animals. Human exposure to bioaerosols has the potential to rise over the next decade as a result of the increasing diversion of biodegradable municipal waste from landfill to open-air composting sites and the use of similar matter in agriculture as a fertiliser.

A recent Institue of Medicine (IOM) review commissioned by Defra concluded that insufficient data were available to set exposure guidelines for most components of bioaerosols and identified significant gaps in knowledge of both exposures and health effects.

The findings of this work will inform policy and practice in the monitoring and regulation of composting, specifically future developments of Defra’s and the EA’s position on composting and potential health effects from bioaerosols and the Environment Agency (EA) / Association for Organics Recycling (AfOR) standard protocol for the monitoring of bioaerosols on composting facilities.

Quality Protocol: Aggregates from inert waste. End of waste criteria for the production of aggregates from inert waste.

The Quality Protocol sets out end of waste criteria for the production and use of aggregates from inert waste. It supersedes ‘Quality Protocol for the production of aggregates from inert waste’, revised edition (ISBN 1-84405-217-6). If the criteria set out are met, the resulting outputs will normally be regarded as having been fully recovered and to have ceased to be waste.

Producers and users are not obliged to comply with the Quality Protocol. If they do not, the aggregate will normally be considered to be waste and waste management controls will apply to its handling, transport and use.

This Quality Protocol was funded by Defra, the Welsh Government and the Northern Ireland Environment Agency (NIEA) as a business resource efficiency activity. It was developed by the Environment Agency and WRAP (Waste & Resources Action Programme) in consultation with Defra, the Welsh Government, industry and other regulatory stakeholders. The Quality Protocol is applicable in England, Wales and Northern Ireland. It sets out the end of waste criteria for the production and use of aggregates from inert waste.

Responses to the consultation: “Proposed repeal of construction Site Waste Management Plan Regulations (2008)”

In 2012 the Department for Environment, Food and Rural Affairs (Defra) proposed the repeal of the construction Site Waste Management Plans (SWMP) Regulations, subject to consultation on the impact of doing so. This was in response to the Government’s Red Tape Challenge, which was designed to remove unnecessary legislation to free-up business. The Government subsequently ran a consultation to ensure it understood the implications of the proposed repeal of the Site Waste Management Plan Regulations. The Consultation ran from 18th June to 16th July 2013.

Food and farming innovation competition: evaluation report -DEFRA

This report evaluates the outcome of the Defra and Technology Strategy Board co-funded 500K ‘Feasibility For Growth’ SME innovation competition to encourage innovation in the agriculture, food and drink sectors and better access to market.

The report covers 21 projects were funded in England, Wales and Scotland by the ‘Feasility for growth’ competition, being some of them focued on waste. All projects were successful in developing innovation solutions, several of which have resulted in commercial opportunities and business growth.
