Waste Gasification process can convert materials normally considered waste into energy and valuable products. In the U.S. alone thousands of tons of a potential source of energy are collected and thrown away each week.
Most of the waste that we discard from our homes and businesses every day – such as non-recyclable plastics, construction debris, used tires, household trash, and sewage – contains energy. WPP Gasification technology can convert the energy in all of this waste into electric power, substitute natural gas, chemicals, biogas, transportation fuels, and fertilizers.
WPP Gasification technology is not incineration. Incineration is the burning of fuels in an oxygen-rich environment, where the waste material combusts and produces heat and carbon dioxide, along with a variety of other pollutants. Gasification is the conversion of feed-stocks into their simplest molecules – carbon monoxide, hydrogen and methane forming a Syngas which is used for generating electricity or producing valuable salable products locally and abroad.
Gasifying waste has a number of significant environmental benefits:
- Reduces need for landfill space
- Decreases methane emissions
- Reduces risk of groundwater contamination from landfills
- Extracts useable energy from waste that can be used to produce high value products
- Enhances existing recycling programs
- Reduces use of virgin materials needed producing valuable products
- Reduces transportation costs for waste that no longer needs to be shipped hundreds of miles for disposal
- Reduces use of fossil fuels
- Dropping the global warming
Waste to clean fuel
WPP Biogas production is a natural process. Biogas is produced by the degradation of organic matter in the absence of oxygen (anaerobic digestion). This degradation, also referred to as mechanization, occurs in natural areas like swamps or in controlled areas like landfill containing organic waste. Mechanization can be artificially controlled by fermenting sewage sludge, industrial or agricultural crops.
Efficient reduction of greenhouse gases
Biome thane is produced from biomass, is therefore a renewable energy resource and does not contribute to the greenhouse effect. The use of landfill or waste for biogas production can even result in a reduction of CO2 emissions as methane leakage is prevented (the effect of which, as a greenhouse gas, is 23 times greater than carbon dioxide).
Biome thane has a very wide range of biomass feedstock
Biome thane can be produced via two different processes – digestion and thermal gasification. Digestion is an anaerobic process where bacteria convert degradable organic matter into methane and carbon dioxide. The feedstock is sewage sludge, household, industrial and agricultural waste. Biogas may also be produced from various agricultural energy crops.
Thermal gasification technique allows even waste-wood from forests or agriculture to be used to produce biome thane.
Biogas requires upgrading to a high level of methane concentration – biome thane – to be used in cars or to be injected into the natural gas grid. Compared to other alternative fuels, biome thane benefits from the extensive availability of biomass feedstock sources.
Sustainable waste treatment and agriculture
Production of biogas from waste may be a key to a more sustainable waste treatment system. Residual digestion-based products may be used in agriculture as fertilizer. Nutrients such as nitrogen, phosphor and potassium are circulated back into the soil.
