Soil, compost and B grade quarry material sustainably produced by the Skipton Soil Recycling Facility will be used and blended to create a range of products such as engineered fill, sub base, sands, gravel, landscape material and soil. These products can be beneficially reused in a variety of applications by the construction and landscaping industries.
The requirement for soil and fill in these infrastructure projects is on the rise. Historically, satisfying this need has been met through the mining of good agricultural soil and river loam from the adjoining green belt and agricultural land; this virgin soil is too valuable for use as fill.
Similarly, virgin quarry rock and clean soil are being mined and crushed to meet the need for fill and engineered sub-base. By substituting recycled material for these valuable resources, we are preserving them for a purpose more suited to their quality or safeguard sites of origin by leaving them untouched – as in the case of good agricultural loam.
New Soil’s sustainable treatment method using tried and tested technology allows soil that would otherwise be destined for landfill, to be beneficially reused in the community. We use a variety of solid and organic liquid waste (food waste) to make soil, growing medium, sub base and gravel for reuse.
As we are not a licensed landfill or dump, but a recycling facility, the soil is mostly sent offsite to be used as an environmentally preferable alternative.
Treating soil in a sustainable way using our proven technology has other benefits including:
- saving a significant amount of material from disposal at landfill;
- reducing greenhouse gases produced by waste material undergoing anaerobic degradation (producing methane) which is approximately 20 times more potent than carbon dioxide; and
- a reduction in hydrocarbon impacted soil treated by unsustainable processes such as thermal desorption (incineration).
Where Will Soil Go for Beneficial Reuse?
A number of destinations have been identified for the reuse of recycled material treated at the Waste Science Soil Recycling Facility, these include:
- Reuse by back loading to the site of origin;
- Rehabilitation of closed landfill facilities, quarry and mine sites;
- Sub-base for road construction, road straightening or road embankments
- Commercial projects such as use as filling or for bunds (i.e. sewage treatment sites);
- Fill for playing fields, car parks and other community projects;
- Use in landscaping projects; or
- Feedstock material with quarried material to meet a product specification at the quarry
Any sites receiving treated material (including the quarry) will have all of the appropriate approvals in place.
