Catalyst Experts

What do catalyst experts or catalyst consultants do? First, let’s define “catalyst”.  A catalyst is a material that is added to a chemical or biological process to improve the yield of a desired product.  Since the catalyst is not consumed in the process, it can be used many, many times for the same process.  There…

First Generation and Second Generation Biofuels

First generation biofuels are those made from sugar, starch, or vegetable oil.  Their feedstocks are those that may not be sustainable or might have an impact on food if used in large quantities.  These original first generation biofuels include biodiesel, ethanol, green diesel and biogas.  Second generation biofuels are those made from sustainable feedstocks as…

Plastic Waste Conversion Expert

Plastic waste conversion is the transformation of plastic waste into usable sustainable products. Depending on the waste plastic composition and level of contaminations, the plastic feedstock could be effectively converted into high-value products through pyrolysis, gasification, and steam reformation. If the plastic feedstock is clean and has an appropriate composition, pyrolysis can be applied to…

Non-Recyclable Plastic Experts

What are non-recyclable plastic experts?  Currently, less than 20% of plastic wastes are recycled or converted to a type of alternative energy, and about 15% is converted to power. Most of the rest ends up in landfills.  Alternative energy companies note that recycling rates have not increased in recent years.  Some plastics are not recyclable…
