Are Biofuels Renewable Energy? - AZoCleantech
WEBAug 27, 2019 · However, there are a number of issues raised by the production and use of biofuels that directly contradict their status as a renewable energy source. When burned, biofuels produce fewer emissions, a reason why they are seen as a preferable alternative to traditional fuels. However, the production of biofuels often involves using land already ...
What are Vehicle Exhaust Emissions? - AZoCleantech
WEBJan 29 2008. This article was updated on the 19th August 2019. Toa55 / Shutterstock. Vehicle exhaust emissions are created when the air-fuel mixture burning inside internal combustion engines releases carbon dioxide back into the atmosphere. Diesel-powered, gasoline-powered, and hybrid vehicles all produce vehicle exhaust emissions; as the fuel ...
The Most Recent Developments in Single-Use Plastic Alternatives
WEBJul 15, 2021 · However, this last characteristic presents a problem – it takes decades, even centuries, to degrade, and almost all of the eight billion tons of plastic that have ever been produced still exist. In commemoration of Plastic-Free July 2021, AZoCleantech takes a closer look at the most recent developments in single-use plastic alternatives.
How Japan is Tackling Pollution - AZoCleantech
WEBAug 19, 2019 · Japan began tackling its pollution problem back in the 1970s when particulate matter levels in the air (PM2.5) reached dangerously high levels around all the major cities. The problems can be traced back to the rapid industrialization of Japan that began during the Meiji period in the 19th century. …
Life Cycle Assessment: an Introduction to Concepts and Applications
WEBMay 5, 2014 · What is a Life Cycle Analysis? A life cycle analysis (LCA) is an internationally accepted methodology (e.g. AS/NZA ISO 14044:2006, ISO 14040 (2006) and ISO 14044 (2006)) for analysing the environmental impacts of a process, product or activity along its “life cycle”. This type of analysis encompasses the extraction of raw materials ...
Genecis: Converting Food Waste into Biodegradable Plastics
WEBJun 18, 2021 · Genecis’s high-performance bioplastics present solutions for two environmental problems: food waste and plastic pollution. They achieve this by creating value for the tons of food that is wasted every year and creating a plastic product that can easily and quickly biodegrade. Plastic pollution is …
What is Pyrolysis? - AZoCleantech
WEBArticle updated on 18/02/20 by Susha Cheriyadath. Pyrolysis is a process of chemically decomposing organic materials at elevated temperatures in the absence of oxygen. The process typically occurs at temperatures above 430 °C (800 °F) and under pressure. It simultaneously involves the change of physical phase and chemical composition and is ...
What is Bioethanol? - AZoCleantech
WEBBioethanol is entirely comprised of biological products, and hence the combustion of bioethanol results in cleaner emissions (carbon dioxide, steam and heat). Carbon dioxide is absorbed by plants and processed via photosynthesis to help the plant grow. This cycle of creation and energy combustion means bioethanol could potentially be a carbon ...
