NEW RENEWABLE POLYMERS FROM BIO-BASED OIL

Bio-oil Pyrolysis as a technique of degrading biomass waste into bio-oil [ 1,2 ]. Bio-oil is considered to be a renewable feedstock for the production of energy, fuels, chemicals, carbon materials and plastics. Bio-oil is a liquid mixture of organic compounds, such as cellulose/hemicellulose derived sugar monomers, sugar oligomers and the derivatives of sugars such as carboxylic acids, aldehydes, ketones, esters, alcohols, and the lignin derived phenolics, pyrolytic lignin as well as a high content of water [ 3 ] .   The production of bio-oil in a large scale can also be achieved in some research groups/companies such as UPM refinery in Finland, Red arrows-Ensyn in Canada, Pyrovac in Canada, Genting in Malaysia, Fortum-Valmet in Finland, BTG-BTL/Empyro in the Netherlands, Kior in the USA and AE Cote-Nord Bioenergy/Ensyn in Canada [ 4 ]. Various researchers have developed the method for upgrading of bio-oil into biofuel via hydrodeoxygenation, aiming to decrease the oxygen content o...

Utilizing Fruit Peel to Turn Old Li Batteries into New

Scientists led by Nanyang Technological University, Singapore (NTU Singapore) have developed a novel method of using fruit peel waste to extract and reuse precious metals from spent lithium-ion batteries to create new batteries , which was published in Environmental Science & Technology on July 9, 2020. The team ha s demonstrated an effective ecofriendly, and sustainable strategy to minimize the environmental footprint of both waste type their concept using orange peel, which recovered precious metals from battery waste efficiently. Further, they have made functional batteries from these recovered metals, creating minimal waste in this process. Fruit peel to turn old into new batteries. Credit to Dr. ASG This considerable approach is to be relatively more eco-friendly than conventional methods, the use of such strong chemicals on an industrial scale could generate a substantial amount of secondary pollutants, posing significant safety and health risks. Therefore, Scientific ...

NEXT-GENERATION FUEL CELL: FROM WASTE-TO-ELECTRICITY

The food waste treatment-based anaerobic digestion has been proven to play a primary role in the electricity industry with high potential economic benefits, which could reduce electricity prices in comparison with other renewable energy resources such as wind and solar power.  -- Ngoc Bao Dung Thi , TDTU, Viet Nam Food and Agricultural Organization of the United Nations mentioned that over 1.3 billion tons of food waste (FW) represents a third of the global food production that is churned out annually [1a, 2] . Both the developed and developing nations have 15-63% of their municipal waste streams to be from FW [3] . In the same way, the world has doubled its total energy consumption over the last two decades, especially due to the population surges in many countries, which was noted by International Energy Agency (IEA) [4] . In this field some of the scientists aims to evaluate the electricity generation from the anaerobic fermentation (AnF) of FW and spent animal beddi...
