Lethbridge Herald (Newspaper) - March 4, 1971, Lethbridge, Alberta Recycling paper is now reality -THE LETHBRIDGE HERALD - THURSDAY, MARCH 4, 1971 By DON OAKLEY, NEA Service The old saying that nothing is deader than yesterday's newspaper needs to be revised, at least as far as the paper itself is concerned. The long-sought solution to the problem of de-inking yesterday's newspaper so that it can reappear as tomorrow's newspaper seems to have been found. Last year, using a new process, three paper-making plants turned 365,000 tons of old newspaper into 320,000 tons of newsprint as fresh as new with a value of about $45 million, reports the Wall Street Journal. That amounted to 11 per cent of the newsprint produced annually in this country. The three plants also paid about $9 million to people who Solid waste survey MONTREAL (CP) - The MacKay family and 20 neighbors in suburban Pointe Claire are searching local garbage cans to find out what their alternative to disposal might be. Officially, the search is called a solid waste survey. It is being conducted in an effort to reduce environmental pollution. Mrs. John MacKay, mother of five and chairman of the citizens' group, said one garbage-collecting family of six Patchwork, profits, litter Generally, though, the scrap metal market is a patchwork of profits and litter. Outside big city areas, the CEQ report found, small auto junk dealers strip cars of parts and the prized metals - copper and lead - but leave the hulks on the lot. Transporting auto bodies to remote markets is costly, and so is shredding and compacting them into a more transportable form. Nathan Addlestone, chairman of Steelmet, Inc., of Pittsburgh, a leading scrap dealer, estimates that a single shredder can cost as much as $3-million. An area with a population of less than 300,000, he says, cannot support a shredder. There may, however, be an alternative in a $41,000 portable machine that squashes cars into 10-inch-high bundles, making them easier to haul to scrap markets. The maker, Mobile Auto Crushers, Inc., of Dallas, says it can flatten 300 cars a day. accumulated the following in a three week period: Forty - two pounds of food scraps, seven pounds of metal, 16.5 pounds of glass-no none-returnable bottles - and 67 pounds of paper. "It gives you some idea of just how much refuse one family can accumulate in a short time, and our worry is what happens to all of it," Mrs. MacKay said. The committee wants to make the public aware that recycling of garbage can restore much of the waste to usable products. , Proponents of the recycling principle are opposed to municipal dumps, where mounds of rotting garbage offend both eyes and noses. COMPOST HELPS The MacKays recommend setting up a family compost heap in the back yard. Food scraps, including meat and even tea bags, can be built up to provide fertilizer for the garden. Another suggestion is newspaper collections. Reprocessing plants will pay about $15 a ton for newsprint-"a great money-raising project for a community group." "And one thing you don't do is buy soft drinks in non-returnable bottles and tins. Not when you consider that the bottles are all but non-destructible; that tin cans take 10 years to disintegrate and it takes a century to get rid of aluminum cans." Once the survey is completed, the committee, will present its findings to the city and "let people know what home owners are really doing vind what should be done to correct it." A public service This tabloid on pollution and recycling is co-sponsored as a public service by The Herald and Pollution Control Southern Alberta. The various articles point out the enormous efforts that are being made in pollution control, but also points to the even greater efforts that will have to be made before pollution is brought into check, let alone under control. Officers of Pollution Control - Southern Alberta are: Ted Wilson, chairman; Larry Weaver, vice-chairman; Mrs. Isobel Goundry, secretary; Dr. Claus Jericho, treasurer and directors: Mrs. Helen Christou, Dr. Paul Lewis, Mrs. Morgan Gadd, Dr. R. King-Brown, Dr. Jim Far, Mrs. Sylvia Campbell and David Balfour. The directors urge readers to save this tabloid for reference. collect and sort old newspapers, including such organizations as the Boy Scouts, Salvation Army and churches. Everybody is talking about pollution and the preservation of the environment. The above is only one example of what some people are doing about it. There are others:  Waste from the processing of citrus fruits (peel, rag and seeds) comprises 45 to 66 per cent of the total fruit. Food Engineering magazine reports that a new conversion process is turning this waste into cattle feed selling for $18 or more a ton.  Speaking of animal feed, researchers at General Elec-trie's Research and Development Centre in Schenectady are experimenting with special strains of bacteria which hold the promise of converting trash into a new animal food source. The bacteria can digest cellulose which, in various forms accounts for up to two-thirds of the solid wastes deposited in municipal refuse dumps.  Engineers at the Franklin Institute Research Laboratories in Philadelphia are developing a soild waste separator that will make possible other reuse of household discards. Shredded trash is fed into the device and a series of vibrating screens, baffles, paddle wheels and gravity separators sort it by classes - paper, soft plastics, glass, metal and hard plastics.  Also in the field of solid wastes, International Patents and Development Corp. in Kings Point, N.Y., has developed a garbage compactor already in use in a number of Manhattan apartment buildings. The fully automated unit, which ejects 80 - pound chunks of compacted trash, eliminates fire hazards and air pollution and lowers time and labor costs involved in handling of waste material.  As for liquid waste, an advanced waste-water treatment process is in the final stages of testing at the University of Michigan. It can consistently remove 95 to 97 per cent of organic waste matter, compared with 80 to 90 per cent by conventional sewage treatment. Most significant, the process removes most of the phosphate and much of the nitrogen in waste water. These contaminants, little affected by conventional methods, are largely responsible for excessive algae growth and the rapid decay and aging of lakes. According to a survey of 248 companies by the National Industrial Conference Board, expenditures for pollution control equipment rose 23 per cent in 1969 to a total of $256 million. The petroleum industry claims that it alone spent more than $1 billion between 1966 and 1969 on air and water pollution control efforts. It's one thing to trap pollutants, but this in turn can cause a problem. Take the tons of fly ash - unburned carbon - being collected daily in factory smoke stacks. One company in Springfield, Ore., does take it, by the truck-load, and converts it into charcoal briquets. What was once a nuisance and a literal eyesore is transformed into a marketable product. Clean air wanted Hydraposal system recovers fibres Drawing upon years of experience, and world renowned expertise in pulping and cleaning waste paper from the pulp and paper industry, Black Clawson Research has developed a process to recover much of the paper fibre (newspapers, bags, boxes, food containers) which normally constitutes over half of domestic and commercial solid waste. The Black Clawson Fibre-claim System operates in conjunction with the Hydrasposal System. After the glass and metal have been removed by the Liquid Cyclone, the slurry is passed through a selective screening process. The useful papermaking fibres are extracted, washed, .sterilized, de-watered and baled, ready for conversion back into paper. The residual plastics, rags, wood particles and food waste are returned to the Hydrasposal system for further processing. COMPOSTING - The Hydrasposal System Provides Ideal Prepara t i o n. After removing much of the cellulose in the Trash for cash NEW YORK (AP) - The Environmental Action Coalition has urged eight million New Yorkers to turn in their trash for cash. In the first major experiment of its kind, the coalition said yesterday it would pay city-dwellers for turning in bottles, cans, newspapers, scrap metal, and rags for re-processing and reuse by major industries. Robert Gale, the coalition's associate director, said workers in the "trash-is-cash" campaign were accepting trash turn-ins at five centres. He said the first payments probably would be delayed until December, after administrative and other costs are determined. The rates are expected to range from $200 a ton for aluminum to $5 a ton for bimetal, the material used for soda cans. Bottles will bring about $20 a ton and newspapers about $10. Gale said more than 300 companies had agreed to accept the trash, with several offering to provide trucks for hauling. Fibreclaim System, and dewa-tering the slurry, (6) the resultant pulp is in ideal condition for conversion into a compost rather than oxidation. It has the proper moisture content, about 40 per cent solids; the metals, glass, and other undesirable components have been removed, and the particle size is correct for the compost digester. MINERAL VALUES - Glass and Metals can be Recovered, Rejects from the Liquid Cyclone (5) contain about 75 per cent glass. Using techniques developed by the U.S. Bureau of Mines, the glass can be separated from the metals, and even be sorted into clear and colored glass. The metals are sorted into ferrous and non-ferrous, and work is well underway to recover the gold and silver. TOTAL RECYCLING - Zero Pollution Possible. The basic Hydrasposal and Fibreclaim Systems have been established through months of large scale pilot plant operation at Middle-town, Ohio. Reclaiming of mineral values from incinerator ash is being done regularly at the U.S. Bureau of Mines experimental station in College Park, Maryland. Composting is being done commercially in the U.S., and is quite common in Europe. Where composting is not economically feasible, the fluid bed reactor is the most efficient equipment known for oxidizing such heterogeneous organic mixtures with no air pollution, and the heat value may be recovered as steam or electricity. 24,000 trees for phone books They're missing. 24,000 of them. 24,000 trees have disappeared from Canada's forests. And they were all used to make up AGT's telephone directories. More than 610,000 copies of AGT directories were printed last year using close to 700 tons of paper; 335 tons of white paper for alphabetical listings, 25 tons of cover stock and 340 tons of paper for the Yellow Pages. Placed in a single pile, they would reach upward just under sine miles. ;
