Does bioDME compete with Food?
Bio DME does not compete with food as it is produced from various wastes including household refuse, waste
plastics, crop waste and other mixed wastes which cannot be separated.
What are some advantages of bio DME?
Commercial vehicles, which are generally diesel powered, consume diesel fuel and release a multitude of harmful
products. These products, which include sulfur dioxide, nitrogen
oxides, and various carbon-based soots, are released into the atmosphere to cause acid rain, dense fog, and
heavy atmospheric damage. However, DME has been tested in
commercial applications, yielding promising results. With minor
modifications, commercial vehicles, diesel trucks especially, can efficiently operate on bioDME
fuel. Not only do they efficiently operate, but they do so
without the release of net greenhouse gases. Further, the fuel
combustion products are safer to humans and environment due to
the absence of atoms such as nitrogen and sulfur in the structure, as well as aromatic
hydrocarbons. As the commercial transportation industry
contributes more than 20% of greenhouse gases per year in the US, a transition to DME use would result in a
strong decline of greenhouse gas emission.
While the end product of lower greenhouse gas production is important, a full life cycle assessment must be
addressed in order to fully perceive the capabilities of bioDME. In
fact, recent studies suggest that bioDME is over five times more efficient than petroleum based
fuels. This is due largely to the source and production of
bioDME. While petroleum-based fuels are derived from a limited
resource, sources of bioDME are widely distributed. These sources
range from wood pulp and coal to household waste and industrial exhaust gases. Because of the capability of bioDME to be produced from these sources, a very
pressing environmental issue is answered. BioDME production is able
to consume a substantial amount of waste from many different facets of the world and yield a clean burning and
environmentally safe fuel.
As household organic waste is a source for bioDME production, the source costs become almost
zero. To add to this benefit, the use and consumption of
household wastes will greatly reduce landfill capacities, resulting in less contaminated land
masses. Additionally, breaking down waste in landfills
introduces massive amounts of methane gas, increasing greenhouse gas densities. By reducing the amount of waste in landfills, this effect can be
minimized. Therefore, in respects to source, bioDME addresses
issues of both cost and environmental impact, which further supports its use as an alternative
fuel. Ultimately, due to the combination of these effects, the
environmental impact actually becomes negative, subtracting from the overall damage incurred on the
environment and greatly reducing production costs.
In regards to safety, bioDME has a comparative safety status similar to traditional fuels. However, unlike gasoline, it does not contain carcinogenic molecules or any
other negative biological effectors. Additionally, unlike
petroleum-based fuels, bioDME does not degrade over time. This
equates to an extended shelf life and simple portability. An
important detail when considering domestic uses is the non-corrosive and non-toxic nature of
bioDME. Because it does not react with metals and is non-toxic,
it is a safe alternative to natural gas for home cooking uses.
