Lethbridge Herald, The (Newspaper) - March 4, 1971, Lethbridge, Alberta Recycling paper -THE LETHBRIDGE HERALD THURSDAY, MARCH 4, By DON OAKLEY, NEA Service The old saying that nothing is deader than yesterday's news- paper 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 >ca.n reappear as tomor- row's newspaper seems to have been found. Last year, using a new pro- cess, three paper-making plants turned tons of old newspaper into tons of newsprint as fresh as new with a value of about million, reports the Wall Street Journal. That amounted to 11 per cent of the newsprint produced an- nually in this country. The three plants also paid about million to people who MONTREAL CCP) The MacKay family and 20 neigh- bors in suburban Pointe Claire are searching local garbage cans to find out what their al- ternative to disposal might be. Officially, the search is call- ed a solid waste survey. It is being conducted in an effort to reduce environmental pollu- tion. Mrs. John MacKay, mother of five and chairman of the citizens' group, said one gar- bage-collecting family of six Patchwork, profits, litter Generally, though, the scrap metal market is a patchwork of profits and litter. Oulside 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, chair- man of Steelmet, Inc., of Pitts- burgh, a leading scrap dealer, estimates that a single shredder can cost as much as An aa-ea with a population of less than he says, can- not support a shredder. There may, however, be an alternative in a 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 none- returnable bottles and 67 pounds of paper. "It gives you some idea of just how much refuse one fam- ily can accumulate in a short time, and our worry is what happens to all of Mrs. MacKay said. The committee wants to make the public aware that re- cycling of garbage can restore much of the waste to usable products. Proponents of the recycling principle are opposed to mu- nicipal 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 news- paper collections. Repro- cessing plants will pay about a ton for great money-raising project for a community group." "And one thing you don't do is buy soft drinks in non-re- turnable bottles and tins. Not when you consider that the bottles are all but non-destruc- tible; that tin cans take 10 years to disintegrate and it takes a century to get rid of aluminum cans." Once the survey is com- pleted, the committee, will present its findings to the city and "let people know what home owners are really doing ond 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 ef- forts 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 newspa- pers, including such organiza- tions as the Boy Scouts, Salva- tion Army and churches. Everybody is talking about pollution and the preservation of the environment. The above is only ono example of what some people are doing about it. There are others: Waste from Hie processing ot citrus flints (peel, rag and seeds') comprises 43 to 6S per cent of the total fruit. Food En- gineering magazine reports that a new conversion process is turning this waste into cat- tle feed .selling for or more a ton. Speaking of animal feed, researchers al General Elcc- tric's Research and Develop- ment Centre in Schcnectady are cxpoiimcnting with special strains of bacteria which hold the promise of converting trash into a new animal food source. The bacteria can digest cel- lulose 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 Laborato- ries in Philadelphia arc devel- oping a soild waste separator that will make possible other reuse of house hold 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 plas- lics, glass, metal and li.ird plastics. Also in the field of solid wastes. International Patents and Development Corp in Kings Point. N.Y has devel- oped a gaibagc compactor al- ready in use in a number of Manhattan apartment build- ings. The fully automated unit, which ejects ftO pound chunks of compacted trash, eliminates fire hazards and air pollution and lowers time and labor costs involved in handling of matPi-uil.

Most significant, the process removes most of the phosphate and much of the nitrogen in waste water. These contamin- ants, little affected by conven- tional methods, are largely res- ponsible for excessive algae growth and the rapid decay and aging of lakes. According to a survey of 248 companies by the National In- dustrial Conference Board, ex- penditures for pollution control equipment rose 23 per cent in 1969 to a total of million. The petroleum industry claims that it alone spent more than billion between 1X6 and 1969 on ah- and water pollution con- trol efforts.
