It is a fact of modern life that more and more household waste is produced annually .Municipal Solid Waste ( MSW) collected by local councils is in many cases take to land fill sites but these are rapidly filling up and the long term considerations of the effect on the environment of potentially harmful materials being deposited are of growing concern.
Recyclable materials are extracted but thousands of tonnes of remaining waste is literally dumped. EU regulations have set targets to reduce these amounts and councils will either have to find some alternative use for this material or face fines.
However a typical waste to energy system provides the answer in with a win/win solution. Local authorities avoid financial penalties by using MSW as feedstock for energy production and benefit from the sale of that energy to the utility companies. A typical waste to energy system will reduce feedstock by 80% leaving a carbon based ash which is harmless to the environment and can be used in many other applications such as aggregates for roads pipe laying beds and in some cased from black carbon re-used in printer toner cartridges.
The waste is delivered to a waste disposal site which has technology to reduce the mass into a residual amount using incineration, plasma, gasification or devolatization system. Systems are chosen on a BAT (Best Available Technique) which includes financial models as well as system types.
The systems conform to all countries health regulations regarding emissions and toxins released into the atmosphere and produce bio energy in the form of Bio Diesel, Bio Gasses and or Electricity.
Most countries have an enforcement order on their utility companies that they have to purchase renewable energy sources rather than produce electricity from their existing methods and a set tariff is negotiated for the supply under a renewable obligation (RO).
The RO is the main support scheme for renewable electricity projects in the UK. It places an obligation on suppliers of electricity to source an increasing proportion of their electricity from renewable sources. A Renewables Obligation Certificate (ROC) is a green certificate issued to an accredited generator for eligible renewable electricity generated within the United Kingdom and supplied to customers within the United Kingdom by a licensed electricity supplier. One ROC is issued for each megawatt hour (MWh) of eligible renewable output generated.
As well as being a profitable industry, the benefits to the Western world and indeed emerging nations is immeasurable. In addition to reducing, and in some cases eliminating, products from landfill we can also extract from existing landfill sites and create energy from the previously deposited waste. This will help in the release of methane and dioxins into the local atmosphere and also to reduce the seepage into water tables below. The dumping sites cause pollutants to enter into their drinking water supply causing health problems and toxic poisoning. We can remove existing and future pollutants from any area of pollutant risk and turn these pollutants into a renewable energy source.
