3.4 Performance Targets

In order to achieve the overall targets set out in Table 3.1, CNES will require as a minimum to meet the specific targets set out in Figures 3.2, 3.3 and 3.4 and Table 3.2 below. These targets refer to the percentage of the total MSW stream collected for subsequent management by each method. It should be noted that they are dependent on a number of variables, in particular future changes in waste growth and composition. A small fraction of waste entering each process will inevitably require final disposal (e.g. rejects from recycling).

Kerbside collections of glass and aluminium in Lerwick are assumed to deliver at least 50% capture of the total quantities available, and in Orkney an additional 1000 tonnes of MSW will be recycled by various means (this target is based on current estimates of the extent to which imports of waste from Orkney for energy recovery can be reduced without adversely affecting the performance or efficiency of the existing plant). A full list of key assumptions underlying the BPEO targets is provided in Annex 6.

(1) Figures are estimates only, dependent on a number of variables - e.g. sufficient secondary material markets; future household waste composition and growth proportion of rejects from recycling.

These targets, together with those arising from the BPEO decisions of the ten other AWPs, will inform the development of national waste targets for Scotland and contribute to the Scottish Executives national 25% recycling and composting target by 2006.

Landfill Directive compliance
The Landfill Directive requirements to divert BMW from landfill must be met. It is likely that the Orkney and Shetland area will be diverting enough biodegradable material through current energy recovery, recycling and composting initiatives to meet the 2010 and 2013 targets. The only factor that could threaten this self-sufficiency is sustained growth in waste arisings, although current forecasts suggest that even if waste-prevention measures fail this will not occur until near 2020. If achieved, the BPEO target of capping the area's MSW arisings at current levels will in itself be sufficient in itself to ensure the 2020 diversion target is met. Successful achievement of the BPEO targets to increase recycling and composting will divert further biodegradable material and support this end. Assuming early (2010) implementation of BPEO targets, Figure 3.5 below compares the levels of BMW to landfill required by the Directive with those expected to be delivered through the BPEO.

It is important to note that by 2020 the existing energy recovery facility will be near the end of its intended life. The area will therefore in any case need to address compliance beyond that date, by planning for and developing appropriate new waste-management facilities.

The Orkney and Shetland BPEO targets will be reviewed on a minimum five yearly basis against monitoring information (i.e. changes in annual MSW arisings, recycling and composting rates), to ensure the area remains compliant with the Landfill Directive requirements.
