  • Eleven million tonnes of waste are produced yearly by the European pulp and paper industry, of which 70% originates from the production of deinked recycled paper. Wastes are very diverse in composition and consist of rejects, different types of sludges and ashes in mills having on-site incineration treatment. The production of pulp and paper from virgin pulp generates less waste but the waste has similar properties to waste from the production of deinked pulp, although with less inorganics [...].

It is a capital and resource-intensive industry that contributes to many environmental problems, including global warming, human tox- icity, eco-toxicity, photochemical oxidation, acidification, nutrification, and solid wastes (Blazejczak and Edler, 2000). Paper is made of natural fibres, either from wood or from recycled materials. Figure 1 below presents a schematic representation of the production system.

  • A pilot study was conducted to assess the feasibility of composting of source separated organic matter of municipal solid waste (MSW) generated in low, middle and high income areas of Karachi city with a population over 14 million. Results of MSW analysis indicate the presence of high percentage of biodegradable organic matter (71-74%), acceptable moisture content (40-50%) and C/N ratio (38-40:1). On windrow composting, not only the volume of waste was reduced but also produced a crumbly earthy smelling soil-like, compost material.
