- How Anaerobic Digestion has Impacted the Canadian Waste Landscape

One of the most significant alterations in the waste management landscape in Canada has been the implementation of anaerobic digestion (AD) technologies for the management of organic wastes. The primary reason for the spread of this technology has been its ability to divert organics from landfill, thus reducing greenhouse gas emissions, and the ability to generate energy products such as renewable electricity and renewable natural gas. At this point, AD developments for food waste have surpassed new composting system development in Canada, and are rapidly gaining in traction in the United States. The technology is already mature in the European context. Both large and small-scale AD facilities have either been constructed or are in planning stages currently, across the country. This presentation use a case-study approach to touch on a number of facilities that are being implemented, the reasons for technology selection, and the expected outcomes from a performance and cost standpoint.

- An Agricultural Biodigestor Cooperative in Quebec: Progress

While biomethanizers have been present for many years in the agricultural landscape of many European countries, in the United States and in Ontario, they are almost absent from the Quebec landscape. Coop Carbone is currently working on developing a biomethanizing agricultural sector in Quebec. How does it intend to lift the barriers that have made sure nothing has happened in this sector in Quebec in recent years? What distinguishes this initiative from the different projects that were born in Quebec in this sector? What are the prospects for development? ... and where are the promoters in the progress of this project? These are the questions that Jean Nolet will try to answer during this presentation.

- Profit from waste mixed plastics: an environmental solution for plastic disposal

Why was the China plastic ban a problem even though we have known and applied the 3R-R strategy (reduce, reuse, recycle, recover) for many years? Waste plastics do not seem to fit in the first 3 Rs. Instead of reducing the production of plastic has consistently increased, reuse is uneconomical and recycle is difficult because plastic resin needs a high degree of purity to be useful. To recover or reclaim value from plastics, technologies such as incineration, Refuse-derived fuels, Gasification, and pyrolysis have been used, but each has significant problems. Sweet Gazoil has developed and patented anti-fouling technologies to transform waste plastics into high quality, readily saleable diesel fuels in small-scale profitable micro-refineries. The organics, metals, and glass separated from municipal waste can be sent to nearby facilities, while the plastics can be profitably transformed into useful fuels, eliminating the need for landfills or incinerators.

- Bio Waste – a renewable energy resource Anaerobic : Fermentation of Separated Solid Organics

Sustainable management of biomass recycling combines energetic with material reuse with the goal of optimizing overall energy recovery and CO2 reduction. This is achieved by removing and capturing bio methane which in turn is used to replace fossil fuels, reducing the amount of compost generated, while achieving favourable treating costs. In 2003 the Germany banned the use of landfill sites. Since then biowaste fermentation has become considerably more important and many successful projects have been realized. HEINZ has actively participated with this and also operates a plug-flow fermentation plant for source separated organics as part of a public private partnership (P3). Our experiences with this plant, as well as from our other projects, we want to highlight the benefits of the dry fermentation process in the treatment of source separated organics.
