HEAT COOKING FARM WASTE INTO ENERGY
CO2 emissions reached a historic high in 2013, with
fossil fuel use and
largely to blame. However, the emissions
increased at a much
slower rate of 2% than
the 3.8% average over
the previous 10 years.
The report, Trends in
Global CO2 Emissions,
Researchers at the University of Guelph have designed a way to create biofuels from “wet” farm waste such
as tomato vines, corn husks, and manure.
The new method uses pressure cooking
to create compact, easily transportable
material that doesn’t degrade and can
be used in power plants.
The research, published in Applied
Energy, notes that the biofuel produces
the same amount of energy as coal in a
While previous biomass products
have been rich in alkali and alkaline earth
metals that damage pipes, the researchers’ biofuel product has fewer corrosive
materials, making them ideal candidates
for use in power plants. The researchers
expect the technology to be commercially viable in five to seven years.
CO2 EMISSIONS REACH ALL-TIME RECORD
reflects a slowdown in carbon emission
generation as the three biggest emitters –
China, the U.S., and the European Union –
look to cut their emissions. The U.S. grew
by just 2.5% while the EU decreased by
1.4% in 2013.
Sharply rising in this year’s statistics
are Brazil, India, China, and Indonesia,
which all posted marked increases from
2012 numbers. While China’s emissions
total continues to grow, it has returned
to the lowest annual growth rate since
2003, excluding the credit crunch years.
EPA EXTENDS BAN ON HARMFUL CHEMICALS
Aiming to eliminate

the U.S., the EPA
has enacted a new
rule to ban the use,

While most of the

Added to the rule are benzidine-
based dyes, which are found in textiles,
paints, and inks; DnPP, used in PVC
plastics; and Alkanes C₁₂-₁₄,chloro,

The action will allow the EPA to
review any products from either
manufacturers or importers using the
now-banned chemicals to ensure public
