Recycling in Canada
The keys to 50 percent waste reduction are the so-called 4Rs of waste minimization Reduction, Reuse, Recycling and Recovery. The 4Rs are a hierarchy, with reduction being the preferable option where possible, it is best not to produce waste at all. If waste is produced, it should be reused if at all practical. The third best alternative is recycling Finally, it may be possible to recover materials or energy from waste which cannot be reduced, reused or recycled
Across Canada, there are many examples of successful recycling programs. As we strive to reduce our wastes, we can learn from the experiences of these pioneers.
One of the best known examples of household recycling is Ontario's "blue box" program, which serves more than 2.2 million households in the province. Householders in participating municipalities are given a blue plastic box in which to collect newspaper, glass, metal containers and, in some cases, plastic soft drink bottles; some cities also collect waste motor oil. Once per week, special recycling crews collect these recyclable materials from blue boxes set out at the curb.
Recycling depots have been established in many rural areas, where distances and collection costs make curbside programs impractical. In Wellington County, Ontario, for example, depots at landfill sites and municipal properties have proven to be very popular. In a pilot project, residents in some areas of the county were provided with blue boxes in which to collect and transport recyclable materials to the depots. Participation and yields increased dramatically, and the county is now providing blue boxes to other residents served by the depots.
Nova Recycling, a non-profit company in Newfoundland, has established recycling buy back centres and mobile units to collect metal and plastic soft drink containers from urban and rural areas in that province.
Increasing attention is being paid to organic wastes (food and yard wastes), which account for more than one third of the residential waste stream. Some municipalities, such as Metropolitan Toronto, are trying to encourage home owners to compost their organic wastes by providing them with low-cost composters. Other municipalities, including cities in Ontario, Quebec and British Columbia, are experimenting with curbside collection of yard waste. and with composting depots.
These are only a few examples of the residential recycling activity taking place across Canada. But residential wastes account for only about one third of Canada's solid wastes. Significant efforts are also being made to recycle commercial and industrial wastes.
Offices, retail outlets and institutions such as governments, schools and hospitals produce more than 20 percent of Canada's solid wastes. Construction wastes account for another 30 percent. The growing realization that recycling can yield economic benefits in the form of reduced waste disposal costs, as well as revenues from the sale of recyclable materials, has prompted commercial enterprises to recycle a variety of materials.
Canada's largest office building First Canadian Place in Toronto is also a model of recycling initiative. Cardboard, fine paper, beverage cans and glass bottles are recycled, wooden pallets are reused, and food wastes are saved for collection by a local pig farmer. In total, approximately 30 tonnes of waste are diverted dally.
Many smaller businesses are finding it profitable to source-separate fine paper and old corrugated cardboard for recycling. For example, in Edmonton, Alberta, a non-profit organization called Paper Chase Recycling hires unemployed young people to pick up and process waste paper from offices for recycling.
Municipal governments are beginning to require consideration of recycling in the early stages of building planning. For example, the City of Toronto recently enacted a by-law requiring that waste management plans be included in development plans. Among other considerations, developers are required to ensure that sufficient space is provided in new commercial buildings to effectively carry out a materials recovery program.
Gypsum wallboard, or drywall, is a significant source of waste, and ran produce toxic hydrogen sulphide in landfill sites. One company, New West Gypsum Inc., has been recycling gypsum water in New Westminster, B.C. since 1987, and is now expanding into Ontario. The company crushes and screens wallboard waste to produce marketable gypsum and paper.
There are numerous opportunities to recycle industrial waste, and Canadian industries are capitalizing on them. savings in waste transport
and disposal fees can be significant, even if the material recycled is not highly valuable.
Canadian entrepreneurs have also been finding new business opportunities in recycling. One Calgary company, Industrial By-Product Recycling (IBR), specializes in finding recyclers or users for industrial by-products.
Boeing Canada's de Havilland Division in Downsview, Ontario recycles approximately 25 percent of its waste stream. Cardboard, computer printouts, office paper, cans and bottles, and scrap metal are all collected for recycling
The Society of the Plastics Industry of Canada has developed a coding system for plastic containers, in order to help consumers determine which containers are recyclable and to assist recyclers in sorting by plastic type. This system is being implemented on a voluntary basis by plastic container manufacturers and users.
The foundry industry in Canada is estimated to generate more than 600,000 tonnes per year of waste sand from mould and core-mailing processes. Highland Foundry Inc. of Surrey, B.C. is one company that has installed equipment to reclaim its sand. Highland has reportedly reduced its purchases of new sand by 90 percent.
Closing the Loop
Simply collecting materials is not recycling. In the past, many recycling programs floundered because the markets for the materials collected were unreliable and
unpredictable. A similar problem faces us now: if we increase the supply of recyclable materials without increasing the demand, materials markets will become glutted and the revenues paid to recycling programs will fall.
Many provincial governments are also introducing policies to encourage the purchase of products made from recycled materials. The governments of Manitoba and Ontario, for example, have both announced such policies.
In Ontario, all levels of government are working together through the GIPPER (governments Incorporating Procurement Policies to Eliminate Refuse) Committee, to develop government purchasing policies that will help reduce waste and encourage the purchase of products made from recycled materials. Members of this committee include representatives from federal and provincial environment and supply departments, municipal governments in Metropolitan Toronto, the greater Toronto regional governments, the Canadian Standards Association, and the Federation of Canadian Municipalities.
Materials markets have always been cyclical, in part because of the lag time required to build new recycling plants when supplies of recyclable materials increase. However, a concerted effort to increase our consumption of
products containing recycled materials will go a long way towards stabilizing markets for recyclable materials and developing sustainable recycling systems across the country.
