Gasification – How to energize Trash!

1) Sustainable Technology: Gasification of Waste to create Ethanol and Methanol

Enerkem, a company located in Canada, is converting garbage into biofuels through gasificiaton.  This technological process converts unrecoverable (non-recyclable and non-compostable) waste into syngas which is made up of carbon monoxide and hydrogen. Syngas is clean, sustainable, and can be produced at a low-cost.  Syngas can be used to replace fossil fuels, liquid fuel, and liquid crude oil as it can be transformed into green diesel fuel.  Enerkem “transforms the syngas into “cellulosic ethanol” and methanol, which can be used to create a clean-burning fuel. Gasoline with ethanol has more oxygen, which helps it combust more completely, thus reducing emissions.”  Enerkem just opened the first commercial-scale gasification plant in Edmonton, Alberta and they plan to keep increasing production of advanced forms of biofuel which can replace gasoline.

2) Sustainability ProblemSolid Waste and GHG Emissions Reductions

Solid waste contains a lot of potential yet only 2% of it is currently used to generate energy and 17 million metric tonnes of non-recycled garbage are produced every week.  Moreover, the continued use of gasoline is adding CO2 to the atmosphere and exacerbating greenhouse gas emissions. Currently, there are 400 ppm of CO2 in the atmosphere and without quick and concrete action, there will be no chance to mitigate the effects of climate change.  In order to address this issue, the adaption of biofuels will be essential for many sectors including automobiles, oil and gas, and agriculture, however, converting to biofuels from fossil fuels will decrease dependence on foreign suppliers, decrease GHG emissions, and reduce overall costs.

3) Technology Stakeholders

  • Enerkem
  • Public Officials
  • City Agencies
  • Sustainable Investors

4) Implementation

  1. Locate medium-sized city where trash is such a problem that exporting of waste is a necessity.
  2. Using the City of Edmonton model, convince local officials and city agencies that the creation of an Enerkem plant will be beneficial.
  3. Raise Capital to create the plant
  4. Initiate Construction while hiring human capital
  5. On-site Testing and Implementation
