    This report describes a programme of research undertaken by Remade Scotland on behalf of, and funded by, the Scottish Executive. The report considers the framework to determine the basis on which stabilised biowaste - waste which has been subject to mechanical biological treatment (MBT) in a mixed waste composting facility - may be used for the treatment of land, particularly sites which are closed former landfills. Generally the waste involved will be municipal solid waste (MSW) collected by local authorities. SEPA proposed in its Composting Position Statement (September 2004) that if a stabilised biowaste can achieve a particular quality standard in terms of PTEs (Potentially Toxic Elements – heavy metals), microbial standards and levels of impurities (glass/metals/plastic), then the material may be suitable for the restoration of old landfills. However, the recovery of stabilised biowaste by land spreading in this way is not considered to be a long term solution. This material and its application to land would require to be assessed on a site by site basis, subject to a risk assessment process and under regulatory control. This report explores the issues involved.
