Toronto # Methanivore: a comprehensive solution to landfill gas emissions through bacterial metabolic engineering # Landfill gasses (LFG) account for 23% of Canada’s methane emissions, a potent greenhouse gas contributing to global warming. Current methods–methane combustion–release excess carbon dioxide and are ecologically harmful. Our solution involves optimizing a genetically-engineered Escherichia coli strain (T-B18) which metabolizes methanol via the ribulose monophosphate pathway (RuMP). We also demonstrated a process concept where methane is separated from LFG using cellulose acetate membranes then converted into methanol by a catalytic reactor, enabling bacterial consumption.

UNSW-Australia # Enzocrete: Cementing Cleaner Concrete Construction with Microbially Induced Calcite Precipitation # When combating climate change, nothing can be overlooked. The cement industry is vital to modern construction but produces up to 10% of yearly anthropogenic carbon emissions. The burning of limestone for conversion into the cement binding agent calcium oxide produces 90% of total cement emissions.
気候変動と戦う際には、何も見過ごすことはできません。セメント業界は現代の建設に欠かせないものですが、年間の人間起源の炭素排出量の最大10％を生み出しています。セメントの結合剤である酸化カルシウムに変換するための石灰石の焼却は、全セメント排出物の90％を生み出します。

UNT # Engineering Methanotrophs for the Synthesis of Value-Added Products # Greenhouse gasses are major contributors to climate change, of which methane and carbon dioxide are some of the most potent. Genetic modification of the methanotroph species, a bacteria able to naturally metabolize methane and carbon dioxide, is a solution to this issue. Considerable work has been dedicated to the genetic engineering of methanotrophs, but a lack in diverse, adaptable, and consistent gene editing remains an issue.
