Paper
I am informed that McDonalds uses large quantities of paper. Almost 14,000 tonnes of this is stated to be directly derived from bleached wood pulp. For example, the cupstock, mainly used for paper cups, is made from bleached wood pulp, according to Casper van Erp's statement. This consists of 10,147,924 kg, 90% of which comes from Enso Gutzeit in Finland. This is only one example of McDonald's paper use worldwide.
The use of woodpulp has environmental consequences some of which relate to forestry practices and some to the processing of the wood to make paper. Wood processing has chemical consequences, due to the breakdown of substances in the wood and to reagents which facilitate that breakdown. Some of these consequences can be avoided or minimised. For example the use of chlorine and other chlorine chemicals such as chlorine dioxide to bleach the pulp creates toxic and long lasting chemicals known as organochlorines, and eliminating chlorine will avoid creating these.
All wood-pulping processes produce toxic discharges. so the ideal now aimed at is to have a closed process in which there is no effluent and in which the waste after bleaching can be burned and some of the process chemicals recovered. If this waste contains chlorine chemicals, then there will be corrosion problems due to hydrogen chloride. The organochlorines present will produce dioxins when burnt. Thus in order to have a closed process, all chlorine chemicals have to be eliminated.
