New waste technologies

The UK has been over-reliant on landfill for too long. One of the alternative treatments involves energy from waste plants which are far removed from the incinerators of the past and provide a valuable alternative to fossil fuel burning by industry. Other technologies such as mechanical biological treatment, anaerobic digestion, gasification and pyrolysis are also becoming more widespread in their used in the UK.

Where does CSS stand?

The UK has been over-reliant on landfill. While well-engineered landfill sites are able to ensure that ground water is not polluted, the capturing of methane is more problematic. It is concern about methane, one of the most damaging greenhouse gases, that has hastened the demise of landfill as a disposal method.

One of the alternative treatments is through energy from waste plants. These modern plants, which are sophisticated combined heat and power facilities, are far removed from the incinerators or “destructors” of the past. The catalytic treatments units reduce pollutants to levels that are well within the permitted levels and certainly better than conventional power stations and many industrial processes.

Viability must not just be possible at a technical level, such plants must also represent good value for money. Energy from waste remains one of the least risky investments and also provides an alternative to fossil fuel burning power stations. Even the bottom ash can be used for some construction processes.

Mechanical Biological Treatment is a well-established technology in other parts of Europe. Different technology providers means that the configuration can vary from one plant to another. However all plants maximise recycling, produce an organic compost–like output and a residual waste stream. CSS is lobbying for clear standards that will maximise the beneficial use of this compost-like organic output.
