Three Decades With Waste-to-Health Bioconversion The solution came to my notice in the form of a two-page article, ‘The Importance of an Earthworm’, in the June 1981 issue of SPAN. I was engaged in farming during this period and was already disenchanted with the use of chemical fertilizers and pesticides. With my background, I could see the earthworm as nature's farmer as well as composter. Without much help from literature or university study, I started some practical experiments with earthworms using the local species. The results were quite impressive and I started talking and writing about my discoveries. Other farmers, however, were following the guidelines set by the agricultural universities. These promoted use of agrochemicals in farming. These killed the earthworms. www.wastetohealth.com/ BIOSANITIZER Ecochip Features, honoured by Bry-Air Award Biosanitizer to fight Swine Flu Eco-Logical Water Treatment and Sanitation using BIOSANITIZER Ecotechnology Cleaning water without chemicals Nanotech for Climate Change Sujala Biosanitizer: An Effective Alternative Medical Waste Disposal Technique Biosanitizer Brief Biosanitizer: An Eco-resource for Water Conservation Biosanitizer: A Resource for Ecosanitation Biosanitizer <short video> Odorless Self-flushing Public Toilet for Slum Sanitation

Release Date: Jun 26, 2012 NTU’s new loo turns poo into power Scientists from Nanyang Technological University (NTU) have invented a new toilet system that will turn human waste into electricity and fertilisers and also reduce the amount of water needed for flushing by up to 90 per cent compared to current toilet systems in Singapore. (clockwise) Dr Rajagopa, Prof Wang, Dr Chen, Dr Giannis, and Prof Chang with the No Mix Vacuum Toilet Dubbed the No-Mix Vacuum Toilet, it has two chambers that separate the liquid and solid wastes. Using vacuum suction technology, such as those used in aircraft lavatories, flushing liquids would now take only 0.2 litres of water while flushing solids require just one litre. earthsky.org/science-wire/ntus-new-loo-turns-poo-into-power

How green infrastructure is making cities more sustainable & hospitable Posted October 11, 2011 The American Society of Landscape Architects has just released a massive database www.asla.org/ContentDetail.aspx?id=31301 of 479 case studies describing the successful application of ”green infrastructure” techniques that collect and process rainwater naturally before it flows into receiving waterways as polluted runoff. The database demonstrates the power of increasingly widespread application of sustainable practices to prevent pollution while simultaneously bringing nature and natural process back into urban environments. The case studies come from 43 states, the District of Columbia, and Canada. This promises to be a great resource: One of the most pressing environmental challenges facing cities and suburbs in the US is the impact of polluted stormwater runoff from developed land – highways, parking lots, rooftops and other impermeable surfaces – into our rivers, lakes, and coastal waters. The federal EPA estimates that more than 10 trillion gallons of untreated urban and suburban stormwater runoff makes its way into our surface waters each year, degrading recreation, destroying fish habitat, and altering stream ecology and hydrology. switchboard.nrdc.org/blogs/kbenfield/how_green_infrastructure_for_w.html

Time to bag some oil Friday November 18, 2011 By Genesee Keevil Andy Lera is a modern-day alchemist. The Yukon innovator has figured out how to turn plastic into black gold. And he could do it for cheap. Using a machine that would fit on a binder, Lera could turn one kilogram of waste plastic into one litre of oil at a cost of 14 cents a litre. Right now, oil in Whitehorse is going for roughly 1.30 cents a litre, plus GST. Whitehorse innovator Andy Lera says waste plastic should be refined into oil, and could provide up to 1/8th of Yukon’s consumption. A bigger model of the machine, roughly the size of a compact car, can convert up to 50 kilograms of plastic into 50 litres of oil in just under an hour. Lera discovered the Japanese technology online. Now he wants to ship some of these machines to the territory, and the Yukon Cold Climate Innovation Centre has offered to help. WATCH: The device in use in Japan. www.youtube.com/watch?v=7P3aUANOYOI[New Inventions: Machine Reverts Plastic Back To Oil (English subtitles)] yukon-news.com/news/25855/____________________________ Whitehorse gets machine to convert plastic into oil Machine is the first of its kind to operate in North America CBC News Posted: Sep 11, 2012 6:04 PM CT Last Updated: Sep 11, 2012 7:08 PM CT A machine that converts waste plastic into crude oil is operating at a recycling depot in Whitehorse. The machine is the first of its kind in North America. Project manager Andy Lera first read about what he calls the "amazing" machine more than a year ago. He read that a Japanese man who was tired of seeing so much waste plastic being burned had found a relatively inexpensive way of converting plastic to crude oil. Lera pitched the idea to Cold Climate Innovation at Yukon College’s research centre. The centre convinced the federal government to share in the cost, which is around $200,000. The machine is now running at P & M Recycling. more: www.cbc.ca/news/canada/north/story/2012/09/11/north-plastic-oil-whitehorse.html

Toronto Zoo backs eco-friendly poo-to-power plant Published Friday, March 20, 2015 12:52PM EDT The biogas facility produces electricity by harvesting methane from decaying organic matter trapped in a heated, oxygen-free chamber. Bida described the chamber as a “concrete stomach” where bacteria break down manure and food waste into methane gas and fertilizer. The gas is then harvested and burned to drive generators that produce electricity for sale to the province, while the fertilizer is used for agricultural purposes. www.ctvnews.ca/sci-tech/toronto-zoo-backs-eco-friendly-poo-to-power-plant-1.2289624
