Optimisation of Waste Logistics (OWL) applied initially to Electrical and Electronic Equipment (EEE)

废物物流优化（OWL）建立在最近的NERC TSEC-Biosys项目的基础上，在该项目中，申请人从多标准决策分析方法中开发了生物能源的可持续性评估框架。该框架的新奇之处在于它能够在涉及废物部分（“质量”）的可持续决策中实现价值最大化。人们希望开发这些优化方法，最初的有价值的和环境显著的问题，废物电气和电子设备（WESTERN）的逆向物流，并随后为更一般的挑战。注.这里描述的优化技术将被NERC归类为技术。重点是为这一应用和后续应用开发这项技术。该技术的应用是在可持续发展，这福尔斯属于NERC的职权范围。这项技术将使科学可持续发展。显然，在废物管理中需要可持续的科学来推动其实践。OWL将首先为WELDERS指令所涵盖的WELDERS开发一个优化的逆向物流系统，其中包括大型和小型家用电器，IT和电信设备，消费设备，如电视，视频和高保真音响，照明，小型电气和电子工具，玩具，休闲和运动设备，自动售货机，医疗设备以及监测和控制仪器。生产商指定回收垃圾的收集点;许多收集点设在市政设施地点。当收集点满员时，属于遵守计划的生产者将Wetcher带走。垃圾不被收集的成本可以通过垃圾填埋费来衡量。水量是指废弃物排放量或其预测量。回收部件的价格可通过回收市场获得。运输成本和排放量是从市政设施地点和向前的处理器位置估计的。因此，实现价值最大化并确定贡献价值的部分是可行的。事实上，这不仅是可行的，而且是一个具有商业吸引力的想法。虽然市场价格存在不确定性，但在可持续性的限制下，不会进行优化以最大化整体价值。额外价值的潜力是相当大的：英国每年产生180万吨，而且还在不断增加，据估计，混合的WEBs通常以每吨150英镑或更高的价格向计划成员收取费用。因此，即使只有2%的系统范围内的改善将价值每年540万英镑。

Optimisation of Waste Logistics (OWL) builds on the recent NERC TSEC-Biosys project, in which the applicant developed a sustainability assessment framework for bioenergy from Multi-Criterion Decision Analysis approaches. The novelty of the framework is in its ability to enable the maximisation of value in sustainable decisions involving waste fractions ('qualities'). It is desired to develop these optimisation approaches initially for the valuable and environmentally-significant problem of waste electrical and electronic equipment (WEEE) reverse logistics, and subsequently for more generic challenges. Note. The optimisation technique described here would be classified by NERC as a technology. The focus is on developing this technology for this and subsequent applications. The application of the technology is in sustainable development, which falls within NERC's remit. The technology will enable sustainable science. There is clearly a need for sustainable science within waste management to advance its practice. OWL will initially develop an optimised reverse logistics system for WEEE covered by the WEEE directive, which includes large and small household appliances, IT and telecommunications equipment, consumer equipment such as TVs, videos and hi-fi, lighting, small electrical and electronic tools, toys, leisure and sports equipment, automatic dispensers, medical devices and monitoring and control instruments. Producers designate collection points for the recycling of WEEE; many are provided at Civic Amenity Sites. When the collection points are full, producers belonging to a compliance scheme take the WEEE away. The cost of WEEE not being collected is measurable by its landfill charges. WEEE quantities are of waste arisings or their forecasts. Prices of recovered components are available through the recycling markets. Transport costs and emissions are estimated from Civic Amenity Site and onward processor locations. It is therefore feasible to maximise value and identify the fractions contributing to it. Indeed, not only is it feasible, it is a commercially attractive idea. Market prices are available though subject to uncertainty, but optimisation does not take place to maximise overall value within the constraint of sustainability. The potential for extra value is considerable: 1.8 m and rising tonnes of WEEE are generated in the UK each year, and it has been estimated that mixed WEEE is often charged at £150/tonne or more to scheme members . Hence even only a 2% system-wide improvement would be worth £5.4 m per year.
