ENVA Composting Site, Blantyre
The ENVA compositing site accepts green waste, primarily from Local Authority food and garden waste bin collections, which is treated through an in-vessel composting process. The process is odorous and has resulted in impact to local communities.
The site is authorised, regulated and inspected by SEPA and operates within the terms of a permit granted under the Prevention and Control (Scotland) Regulations 2012.
SEPA take complaints of odour from this site seriously and are actively working with the operator to address the issues and secure compliance.
On-site treatment of waste
Date published: 01 April 2023
From 1 April 2023 ENVA have ceased treating waste on-site. However, mixed biodegradable (food and garden) and green (garden) waste continues to be accepted for bulking and transport to alternative sites for treatment.
The proposed improvement works include:
- enclosure of the maturation shed
- installation of an Aerated Static Pile (ASP) system in the maturation shed, and treatment of air via a new bio-filter
- upgrades to the existing composting vessels (IVCs)
SEPA continue to consider these infrastructure upgrade proposals to be in line with Best Available Techniques (BAT) to manage odour on a composting site.
What we have done
Compliance with an enforcement notice was achieved by 1 April. SEPA continues to assess permit compliance. The operator is undertaking work to resolve permit breaches with respect to surface water management and smaller-scale potential odour sources.
