Biostabilised Organic Fines
In 2019, five composting facilities in Ireland accepted organic fines for biostabilisation. Organic fines arise from the mechanical treatment of residual waste. There has been a notable rise in the treatment of organic fines at composting plants in Ireland, up from around 50,000 tonnes in 2013 to 138,000 tonnes in 2018 and 152,000 tonnes in 2019. This reflects the fact that most residual waste in Ireland is now pre-treated mechanically at waste facilities, for example by trommelling, before it is sent for recovery or disposal. The organic fines arising from this pre-treatment process undergo biostabilisation to reduce their biological activity to an EPA-approved standard. The biostabilised fines can then be used as landfill cover or disposed of at landfill without giving rise to odour and greenhouse gas emissions.
