Spreading waste directly on land
Testing and nutrient balance assessments can be carried out together with
the application of a Waste Management Licence Exemption. Plant bioassay
research work can be undertaken to determine the beneficial properties
of a compost or organic material to be used on land.

Soil manufacture
Synthetic soil use (the use of combined soil-forming materials) has traditionally
been undertaken whenever a shortage of soils has arisen. Following placement
on an area to be restored, a mineral soil-forming material would then,
usually, be augmented with some form of organic matter, very often some
form of sewage sludge which would need to be imported into the site. Many
other different organic matter sources are however now increasingly available
to help in the production of synthetic soils for land restoration. To
satisfy the Waste Management Licensing regulations, agricultural or ecological
benefit will need to be proved and therefore information on the plant
nutrients to be supplied to agricultural plants or mainly soil structural
improvements to be imparted for ecological benefit must be quantified.
With all synthetic soil manufacturing, whether undertaken on the ground
or prior to application, some degree of initial testing and then research
studies are essential to satisfy both the regulatory authorities and provide
the site operators with practical achievable procedures and goals.
On-farm/site composting
For on-farm composting, a site survey and Risk Assessment for the local
planning authority and the Environment Agency may need to be carried out
in the first instance. On-farm composting planning applications, operational
advice and cropping regime nutrient management plans are undertaken. Life
Cycle Assessment to ISO 14040 can be performed.
