While asking around for newspaper donations, I often meet with reluctance and wondered why? Ten years ago a kilo of old newspaper fetched only a meagre Rs 3/- , today the raddi-wala (the guy down the road who buys scrap) pays an enticing and irresistible Rs 7/- per kg. I promptly made a trip down there to broker a deal with him for a steady supply of newspaper for our paper bags. He tells me that newsprint companies in India have begun to recycle old newspaper into newsprint. In the past newspaper was recycled into boards or brown coloured paper for packaging and boxes because recycled newsprint turns a dull greyish colour unsuitable for printing. Indian newspaper companies have found ways to deink newsprint pulp and retain its brightness for printing purposes. Mammoth deinking machines do this job. Featured here is a small one, just to demonstrate the process.
Waste newsprint is defibered in an aqueous bath to which a deinking agent is added. The resulting slurry or pulp is rinsed, drained and formed into paper sheets.
Much as I am happy about its positive effects on the planet, I am still in need of copious quantities of newspaper to meet our newspaper bag orders.
