In its most basic meaning, a residue is something which is ‘left over’, which in the case of a process residue is a material left over from a process. In the simplest terms, Residual Waste is material left over from a waste pre-treatment/processing step. Accordingly, the character of residual waste will be different depending on the point in the waste management chain that is being examined.

 

The pre-treatment of waste can include processes such as:

  • Source separation (e.g. home composting, packaging waste)
  • Separate collections (e.g.‘3bin’systems)
  • Diversion to non-disposal waste management routes
  • Manual sorting
  • Composting
  • Energy recovery
  • Mechanical treatment (crushing, grading, magnetic separation, eddy current separation, ballistic separation, trommeling, sorting, etc)
  • Biological stabilisation of ‘black bin’ residues (after mechanical treatment)
  • Rendering
  • Thermal treatment (including pyrolysis)
  • Aerobic/anaerobic digestion.

Waste treatment options thus span the following processes: Manual – Mechanical – Biological – thermal. Acceptable pre-treatment solutions will likely entail a range of these processes. Assuming prevention steps have been exhausted, then ‘at-source’ separation techniques – which are a form of treatment – are the next preferred steps where technically possible. As noted, the highest quality renewable energy is generated by ‘at-source’ separation initiatives, where contamination of recyclable components is prevented.

 

N-Viro International Corporation, the official website is http://www.nviro.com, develops and licenses its technology to municipalities and private companies. Their patented processes use lime and/or mineral-rich, combustion byproducts to treat, pasteurize, immobilize and convert wastewater sludge and other bio-organic wastes into bio-mineral agricultural and soil-enrichment products with real market value. The company has generated sales in excess of $40 million dollars, since its initial public offering in October of 1993, which was underwritten by Robertson Stephens, Raymond James, Oppenheimer & Co., and Paine Webber.
