      2. other waste is £32 per ton. Reason why waste being used in Argyll to reclaim land.
  2. management approches
    1. prevention, minimisation, recycle, reuse, incineration, landfill
  3. Scotland
    1. expectation to recycle more (from 5% to30%), compost more(1%- 15%) and covert to energy (1%-15%) every year (2002-2020) figure by Scottish gov. made in 2003

    1. people and environment need to be protected from radioactive waste
      1. time dependent, long life long protection neeed
2. Disposal
  1. HLW: underground Tanks, which its stored
  2. Looking for volunteer councils to have HLW deposit sites
    1. west Cumbria council volunteered as they ahe experience with HLW due to nucular site. Backed out
    2. benefits include jobs and economic.
  3. regulators
    1. Sepa is scotlands
