co-disposal

Any potential for acid mine drainage would also be reduced by co-disposal.

Blended co-disposal of waste rock and tailings with:

On 16 July 2004 the co-disposal of hazardous waste with non-hazardous waste at the same landfill site was prohibited.

No co-disposal with organic solvents.

However, it is right that she should be congratulated because she has accepted wholly now the principle of abolition of co-disposal.

Where liquid or solid hazardous waste is mixed with other biodegradable wastes to effect treatment by the microbial processes in he landfill, the process is known as co-disposal.

The Galore Creek site would be used for co-disposal of tailings and both potentially acid generating and not-potentially acid generating waste rock.

However, co-disposal has been successfully implemented by several designers including AMEC at, for example, the Elkview Mine in British Columbia.

Banning co-disposal of hazardous and non-hazardous wastes and requiring separate landfills for hazardous, non-hazardous and inert wastes.

Henderson Geotech has provided bund and wall designs for the CHPP waste Co-Disposal Area that accommodate process constraints and preferred construction methods.

The LFD aims to prevent co-disposal of hazardous wastes from July 2004 and ban certain wastes to landfill e.g. tyres, liquid wastes, explosive, highly flammable, corrosive and oxidising wastes.

Compared with the disposal of pure CEPT sludge, the co-disposal of dewatered sewage sludge with other solid wastes commonly found in Hong Kong results in lower compressibility, smaller settlement, but higher hydraulic conductivity.

New management methods that improve the physical and (or) chemical stability have hence been developed to reduce environmental risks associated with tailings storage, namely, densified tailings, environmental desulphurization, covers built with tailings, and co-disposal of tailings and waste rock.
