Page it THE HERALD Wednesday May 1189 Acton student wins science bronze ByBENDUMMETT Herald Stair environmental pro- start with you was the self proclaimed motto inspiring Grade Acton High School stu dent Jennifer Pearce to build an award winning working model of a sewage treatment plant Ms won a bronze medal for her project entitled What hap pens after you flush in the Senior Engineering category at the recent Canada wide Science Fair in St Johns Newfoundland Torontos garbage problems and an interest in attaining a better understanding of the viable ways society can deal with its pollution problems were two reasons Ms came up with the idea of the model plant The project in- itially started off as Ms Grade 11 science independent research project The miniature sewage plant is modelled after Actons plant Ms Pearce said It is an elaborate con traption of copper pipes an aquanum and plexiglass A word report explaining the work Grade Acton High School student Jennifer built this work ing model sewage treatment plant that recently won a bronze medal n the Senior Engineering category of the Canadawide Science Fairheld recently in SI Johns Newfoundland LINDA smith fatuous of the model and a VCR tape recording of how sewage at the Ac ton plant is treated accompany the model Ms said the tape ding was used so that people would be able to compare the workings of her model with the Acton plant s Ms Pearce said water treated by her sewage plant came within one milligram per litre of meeting the governments standards by which actual sewage treatment plants have to abide Ms spent approximately three months building the model having had to go back to the draw Ing board three times before com up with a working model Ex for the transport case that her father helped build Ms Pearce constructed the miniature plant herself Ironically her success hasnt in spired Ms Pearce to pursue a career in the physical science rather she wants to study sports medicine But she said a lot of people understand this To get to the CanadaWide Science Fair Ms Pearces project placed first in the senior division of the Hamilton District Science and Engineering Fair held the first week of April Other winners in the Canada Wide Science Fair coming from schools in Halton include Jonathan Moncneff a Grade 8 student at Kilbride Public School who won a bronze medal in the Junior Life Sciences category for his project In the Minds Eye and Menisha Ghai a student at Lester B Pear son High School in Burlington who was awarded a silver medal in the Senior Life Sciences category for her project Inhibiting the Gut Reaction to consider cardboard ban for residential garbage A Regionwide cardboard ban for residencesr could increase the amount of recycled waste in Halton from to per cent if passed by Regional council next week Although Halton Hills already collects corrugated cardboard as part of its recycling program the remainder of the Region could join in collection beginning January Previous bans on cardboard col lection in the Region were restricted to commercial and in facilities The new ban would also affect residences The Region will telt municipalities not to accept cor rugated cardboard at local transfer stations if the cvardboard ban is passed The cardboard must be clean before it is collected Cardboard containing garbage will be left at the residence with a note attached asking the resident to dispose of it separately Since the industrial cardboard ban was Imposed in December Hallons waste collection has been reduced per cent says a Regional report The four municipalities in have programs in place to pick up commercial and industrial card board Hills and Milton have agreements with Disposal Limited to pick up cor cardboard The Region says three to five per cent of garbage by weight would include corrugated cardboard A compactortype truck would be needed to compress the cardboard but the Region will not want to buy a third truck to process the material They will separate the waste in recycling trucks The most feasible ways of col lecting cardboard with these vehicles is to mix cardboard in the same compartment with newspapers says Regional staff The staff says the price of collec ting the estimated 2500 to 3000 tonnes of cardboard annually could be offset by the sale of the card board material Corrugated cardboard is presently worth a tonne on the market but the Region says the cardboard market can be volatile and prices can fluc tuate But we will realize savings in our waste disposal expenditures said Regional commissioner of public works Bob Moore The Region pays a tonne for transfer haulage and tipping fees to an energy from waste plant in New York However these sav ings will be offset by lower tipping feerevenuessaidMr
