With the assistance of the National Research Council of Canada, SALT has developed a process to manufacture durable products from the remaining materials (co-mingled plastics, glass, rubber, carpet, etc.). Items such as utility poles, railway ties, marine wharves and landscaping products can be manufactured in many shapes or sizes. The products are exceptionally cost-effective, impervious to erosion, non-toxic, and exhibit high tensile and flexural characteristics.

Alternatively, high BTU waste products such as co-mingled plastics and carpet can be processed into biodeisel or pelletized for use as a fuel source.

Either of these companion technologies will provide dividends to the landfill owner.
When the aerobic cycle has completed, the site can be excavated using open pit mining techniques. Composted material is removed and recyclable materials (metals etc.) can be recovered. Any hazardous materials such as batteries, propane cylinders and chemical drums can then be disposed of appropriately.

Well Drilling

SALT's aerobic process immediately and dramatically changes the condition of a landfill. Wells are drilled to various depths in order to inject air and moisture. Anaerobic bacteria quickly perish and are replaced with aerobic bacteria, which rapidly decompose the organics. Landfill leachate and/or municipal sludge can be used as the moisture source, resolving yet another issue!

Environmental benefits are immediate. Methane production ceases within 2 to 3 weeks and odours are virtually eliminated. Organics decompose in 24 to 36 months. Leachate quality is vastly improved and volume is significantly reduced. As well, the site will compact and visibly "slump", recapturing up to 30% of the original airspace.

The aerobic process can be applied to both operating and closed landfills.
Sustainable Aerobic Landfill Technologies
Traditional landfills are anaerobic (oxygen-deprived) and pose environmental risks to air, water and land through greenhouse gas emissions, intense odour production and leachate generation. (Leachate is a nasty-smelling landfill liquid which often contaminates groundwater). Anaerobic landfills are merely long-term garbage tombs that are extremely slow in decomposing organics (taking upwards of centuries).

SALT's sustainable landfill remediation solution resolves all traditional landfill issues.

The system consists of three processes:
