Many countries in the world today have reached the point of full utilization of their forest resources, to satisfy their need for lumber and pulp and paper products. Others have reached the point where their consumption is far in excess of the capacity their domestic forest stands can sustain and they are net importers of these products. Still fewer have developed the practice of recycling these products to any appreciable extent. Canada and United States are approaching full utilization and have only accomplished a recycling rate of approximately 20% of paper and paperboard products. On the other hand conservationists are calling for more efficient utilization of resources, ecologists are calling for less waste and less pollution, while the burden on city garbage collection facilities, 50% of which is paper products, is increasing exponentially. In this thesis the technical processes required to make first quality newsprint from recycled newspaper are shown to be available. The economics of such a plant is examined in detail leading to the judgment that it is economically sound. The conclusion is reached that a 300 ton/ day newsprint mill can be entirely supported by locally generated waste newspaper in a city of three million population or over. Furthermore, it is concluded that if the collection and transportation of waste newspapers is not impeded by governmental regulations or unanticipated competition in the feeder cities, such a plant is still economically feasible after allowing for water barge transportation of the raw materials as far as 200 miles. / Business, Sauder School of / Graduate

This thesis investigated the technological economics of waste paper recovery and recycling in UK. The major problem in waste paper recycling is still the removal of contraries, although technological developments have so far been able to remove some of them. The costs incurred by the local authorities in recovering waste paper were investigated. Local authority costing was found to be inconsistent and many of them did not include all the relevant indirect costs and savings, so that many local authorities claimed to be making heavy losses in their operations. Full accounting incorporating all the relevant indirect costs and savings have shown that most local authorities incurred much smaller losses and in some cases profited from their waste paper recovery operations. A general computer model was developed to allow local authorities to check the viability of their on-going operations and another computer model was developed for an investment appraisal of a proposed waste paper recovery operation. Multiple regression models were developed to forecast the demand of waste paper in the short term and the long term. The cost to the mill in recycling waste paper was also examined. Waste paper recycling can only be increased by improving demand for waste paper based products. Various alternatives for diversifying the markets for waste paper were investigated, particularly those outside the paper and board industry. The government's role in helping to inc~ease waste paper recovery and recycling was examined and some government actions that could be taken were proposed.
