LANDFILL MINING

INTERNATIONAL REPORTS

The Cayman Islands Government has considered a range of solid waste management solutions, predominantly focused on remediation, landfill mining and Waste to Energy. In this section, international reports on best practice related to all these options have been compiled, using landfills and jurisdictions most relevant to the Cayman Islands.

LANDFILL MINING REPORTS

Landfill Mining refers to processing old waste that has already been landfilled. Research indicates that the reason for mining old landfills, in the very limited number of cases worldwide, is very site specific. Usually the benefits derived from mining an old site include recovering fill for cover material at an active on-site disposal area and recovering landfill capacity.  Sometimes the process is employed to move waste from an unlined area to a lined area to reduce the potential for groundwater contamination.  Rarely, the recovered material has been separated out for recycling or used to feed a Waste to Energy facility.  A new term has been coined for this process of recycling and recovering energy from previously buried waste; Enhanced Landfill Mining (ELFM). When considering ELFM there are a variety of potential options when it comes to selecting a Waste to Energy technology. These include relatively few reliable and proven technologies, as well as many new and untried forms.  Consequently the importance of pre-qualifying technologies is critical.
