Tire Pyrolysis Is Being Rolled Out In The USA

Let’s stop filling our landfills with old tires!

According to the U.S. Environmental Protection Agency (EPA), about 100 million pounds of tire components discarded during the manufacturing process are dumped in landfills nationally each year because the body ply – the tire’s largest component – can’t be effectively recycled. That is, until tire pyrolysis gains more of a foothold throughout the industry.

Pyrolysis of scrap tires offers an environmentally and economically feasible method for transforming waste tires into heat and electrical energy.

BioEnergy Waste Management’s CEO, Salmon Zafar, noted that pyrolysis is one of the most popular methods for disposal of scrap tires in many parts of the world. Tire-derived fuel (TDF) or pyrolysis oil is one of the largest applications of scrap tires in U.S., however, it is currently being challenged…due to the steep fall in oil prices in recent years.

The article goes on to explain that there is a need for more investment in this technology. Demand will grow over time as population increase cause more pressure on the oil industry.

An innovative startup company, RVS Rubber Solutions, created by two university students, has developed a new technology that extracts the rubber and steel from within the components in a cost-effective and environmentally friendly way.

Talking About The Power of Poo

Used throughout history, and still used today in many parts of the world, human waste has a bad reputation as a fertilizer. Why? The chance that pathogens can be carried and inadvertently passed on through the food products grown with “night soil”.  Not to mention the unpleasant, distinctive odor that the garden/crop lands take on with this practice.

Thanks to Pyrolysis, and with the ingenuity of its Swiss developers, human saste is being collected in mobile ‘dry’ toilets, then taken and processed by pyrolysis to become terra preta, a very fertile substance for growing plants of all kinds.

SWITZERLAND • If the banana trees at Zoo Zurich are particularly lush, it is thanks to a fertiliser with an unusual ingredient: human waste. During spring last year, zoo employees cleared a bamboo grove in Zurich’s Masoala Rainforest to plant the trees.

Pyrolysis Method Could Convert Logs to Bio Oil

We came across this post on the Laboratory Equipment website and wanted to share it with our readers.

The dead trees of the world’s forests could be a valuable and efficient source of a kind of oil, according to new research published by a team of scientists at the University of Washington.

Fast pyrolysis, the process of heating wood at extreme temperatures in oxygen-less environments to create “bio oil,” would be a viable source of energy with a new method presented by the researchers in the journal Fuel.

The method involves breaking down woodchip-sized pieces – a significant improvement from tiny wood pellets just 1 to 2 millimeters in length, they write.

Smallest 3D printed lattice structure in the world!

making-the-worlds-smallest-ultra-strength-3d-printed-lattice-structureYou will not believe your eyes when you realize just how small the world’s smallest 3D printed lattice structure is! We came across a post on 3ders.org and thought it would be of interest as it uses the pyrolysis process as the method of shrinking the lattice structure to its record size. Scientists reported that “The pyrolysis process not only shrank the lattice, it also effectively transformed the polymeric structures into glassy carbon, a high strength, low density material, outmatched only by diamond for its strength-to-density ratio. After pyrolysis, the scientists found that the 3D printed lattices were ultra-strong, with impressive strengths of up to 1GPa with a density significantly lower than the density of water, which is 1,000kg/m³.”
