Western Canada has had record-breaking…

greenhouse gases on the planet. The depletion and of petroleum and to their harm to the environment, biofuel arise as a promising option to replace fossil fuels in the future. Biofuel are derived from biomass conversion with many different examples such as biogas, biodiesel and bioethanol as the most currently used, and biofuels are considered not to leave a carbon print to the environment since they are considered CO2 neutral (1). The total dependency on fossil fuels such as gasoline, natural…

From surfing, swimming, fishing, scuba diving, and going on boat rides on the beach most of us don’t really know what’s going on in our oceans. In reality besides the waste that goes in there’s actually acidification in our waters. Acidification is when the ocean uptakes carbon dioxide from the atmosphere, this also means the pH levels are lowering. The ocean acidification is negatively taking over our environment and there are barely any benefits that come with it. This essay will provide…

While it isn’t entirely clear where all of this waste is diverted, it is evident that 89% of food waste is being composted or anaerobically digested for conversion to biogas, any clothing waste is being donated or recycled, and all construction waste is being recycled. On top of this, the company reported a construction waste reduction of 50%. The highlights include an 88% usage of sustainable wood and 100% sourcing from…

Over the past few decades, increasing research and development efforts toward value addition and efficient utilization of nutritionally rich agro-industrial residues have been gaining attention around the world. Several industrial residues, such as whey, sugar beet pulp, cassava bagasse, apple pomace, citrus waste, coffee pulp/husk, etc., have been studied as model system. They are either used as microbial substrates in fermentation or are subjected to the extraction of bioactive molecules1-4.…

“The U.S. Energy Information Administration (EIA) estimates that about 11% of world marketed energy consumption is from renewable energy sources” (U.S. Energy Information Administration, 2014). Renewable energy is often referred to as green because it is a strong for the environment, or so we think. Media covers a wide variety of global warming and greenhouse gas stories, but nobody seems to have a solution to the problems. This could be in large, because being green is such a vague topic. To…
