The carbon footprint calculations give a good indication of the environmental benefit of the remanufacturing process. However, factors such as the consumption of virgin materials, fossil fuel depletion and waste disposal are not fully taken into account. Generally, remanufacture will reduce these effects compared with the construction of a new RDC. Therefore RDC remanufacture will have a larger benefit if the total environmental footprint is considered. For illustration, reusing steel saves 96% of the environmental impact over virgin steel. 8 It is also important to state that the ability to remanufacture is dependant on the build quality of the RDC. If there is significant corrosion, (which is likely with the absence of a stainless steel base) then remanufacture is uneconomic, meaning the only suitable option for such cases is disposal. This reduces the potential benefit from remanufacturing. 8 “Reclaimed building products guide”, WRAP, 2008 Page 20 of 38
©Centre for Remanufacturing & Reuse 2009 3 Market review Understanding current, future and potential activity within the RDC remanufacturing industry is central to determining its relevance to the UK economy and the corresponding environmental impacts. This section explores trends in market size of the industry and estimates the maximum economic and environmental contributions theoretically achievable through remanufacturing RDCs. It also outlines the views and experiences of buyers of remanufactured RDCs, which is necessary in understanding the motivations for and against purchasing them. 3.1 Current activity and future activity The appendix describes available literature on the estimated market size for both new and remanufactured RDCs. A summary of this analysis is outlined in Table 3.1. Table 3.1: The (2008) estimated market for RDCs in the UK Type Total stock (units) Estimated old stock to be renewed or refurbished (units) Stock refurbished each year (units) New stock purchased to replace old stock (units) Additional new units to increase capacity (units) Integral 412,411 58,360 7,003 51,357 23,344 Remote 217,611 32,647 3,917 28,725 8,370 Total 630,023 91,002 10,920 80,082 31,714 By analysing trends in the market situation since 1998, we have projected the future market for both integral and remote RDCs. Listed below are some assumptions used in this model: From 1998 to 2005 the remanufacturing market dramatically reduced from approximately 15% of the replacement market to approximately 6%. This decline was caused primarily by cheaper new units becoming available from continental Europe and the Far East. There was some improvement in the market between 2005 and 2008, with remanufacture increasing from 6% to 12%. The volume of remanufactured units is likely to increase until 2013, however, due to the growing frozen food sector: it is likely that the market share for remanufactured units will remain 12%, after which the remanufacturing share of the marketplace is expected to increase due to a slowing in the expansion in overall chilled and frozen food sector.
