36 Evaluation of Opportunities for Converting Indigenous UK Wastes to Wastes and Energy AEA/ED45551/Issue 1 Most growth forecasts use growth rates for MSW of 0.75% per annum as this reflects Scenario 3 in the national waste strategy. This suggests that MSW will be a stable source of feedstock for energy in the foreseeable future. Increasing the recycling rate to the 2020 target of 50% will require large-scale collection of food waste from households; the England waste strategy promotes this because of both landfill gas reduction and energy recovery if food waste is treated using anaerobic digestion. This is a significant opportunity to recover renewable energy. 4.2 Commercial and Industrial Wastes (C&I) 4.2.1 Definition Commercial and Industrial wastes are those arising from premises used for industry, trade or business. In 2002/3 Industrial and Commercial waste in England totalled 68 million tonnes. Of this about 38 million tonnes was attributable to industry and 30 million to commerce. 4.2.2 Composition The individual sector that produced the most waste was the retail sector, which generated nearly 13 million tonnes of waste. This was followed by food, drink and tobacco manufacturing, and the professional services and other businesses, both producing more than 7 million tonnes, and the coke, oil, gas, electricity and water industries at just over 6 million tonnes. Table 8 Commercial and Industrial waste arisings 2002-3 for England and Wales Type of Industrial Waste C&I Arisings (‘000 tonnes) Manufacture of pulp, paper and paper products 1,800 Food, drink and tobacco 7,200 Textiles, leather goods 1,200 Wood and wood products (inc. furniture) 2,000 Publishing, printing and recording 2,200 Production of coke, electricity, oil, gas and water 6,200 Manufacture of metals, fabricated metal and machinery and equipment 7,700 Manufacture of motor vehicles and other transport 1,500 equipment Other non-metallic mineral products 2,300 Retail, including motor vehicles, parts and fuel 12,800 Hotels, catering 3,400 Transport, storage and communications 2,200 Commercial business, finance, real estate and 7,200 computer related activities Public administration and social work 1,400 Chemical and other 5,300 Education 1,900 Miscellaneous 1,500 Total 67.9
Evaluation of Opportunities for Converting Indigenous UK Wastes to Wastes and Energy AEA/ED45551/Issue 1 This demonstrates that industrial and commercial wastes contain a vast range of materials, and that discussing them as a single homogenous mass can be misleading. Table 9 gives more detail about the possible content of commercial and industrials wastes, based on an Environment Agency survey covering England and Wales. Table 9: Composition (‘000 tonnes) of commercial and industrial waste in England Commercial Industrial Total Chemicals 1,942 5,692 7,634 Metallic 604 2,727 3,330 Non-metallic 8,651 5,181 13,833 Discarded equipment 262 88 350 Animal & plant 2,152 4,143 6,295 Mixed/general waste 15,569 6,056 21,625 Common sludges 154 761 915 Mineral wastes 987 12,939 13,926 Total 30,320 37,587 67,907 Table 9 shows that: • Mixed/general waste is the largest category, representing 32% of total C&I arisings (a figure of 37% was determined for the survey in Northern Ireland), and 50% of commercial waste arisings • Mineral wastes represent about 20% of total C&I arisings. This includes 6 million tonnes per annum of ash from pulverised coal fired power stations, of which about 3 million tonnes is currently being recycled. 32 • Non-metallic wastes represent about 20% of total C&I arisings. This category includes recycled paper/cardboard, and over 85% of the total arisings of this category are recycled. 32 The current classification of pulverised fuel ash as a waste is the main reason why only about 50% of it is currently recycled. The Waste Protocols Project is currently considering whether the ash could be classified as a product for specified recycling uses 37
