Hazardous waste management

  • Hazardous waste is any unwanted material the

disposal of which poses a threat to the environment, i.e. it is explosive, flammable, oxidizing, poisonous/infectious, radioactive, corrosive and/or toxic/ecotoxic.

  • Sources of hazardous waste include hospitals, timber

treatment, petrol storage, metal finishing, paint manufacture, vehicle servicing, tanneries, agriculture/horticulture, electricity distribution and dry cleaning.

The Waste Management Hierarchy

  • In deciding on the best method for managing

any waste there is a hierarchy for decision making which addresses issues such as sustainability, cleaner production, health, safety, and environmental protection. It is applied to existing or proposed practices, examining and testing these at each level

  • Starting at the top of the hierarchy.

Hazardous waste management

  • If recycling, re-use, minimization aren’t possible

hazardous waste need to be treated

  • The waste can be treated chemically (i.e. by

neutralization, oxidation, reduction, hydrolysis, precipitation), physically (encapsulation, separation), biologically (using microorganisms) or thermally (incineration & co-processing). Most treated waste is then deposited in landfills . To prevent landfills themselves being environmental hazards, generally control the types of waste that can be deposited in them and the landfill design

  • Inform Project management
  • Increase safety measurements (full face masks)
  • Use fire extinguisher for first approach

The Basel Convention on the Control of Trans-boundary Movements of Hazardous Wastes and their Disposal is the most comprehensive global environmental treaty

  • n hazardous and other wastes. Basel

Convention was negotiated in the late 1980s, and entered into force in 1992. Basel Convention acts is based on :  International and validate agreements, facilitating sound waste management.  Technical Guidelines submission, to promoting regulation and control of sound technologies for waste treatment/disposal.

Co-processing Technical Guidelines are now OFFICIAL RECOMMENDATION of United Nations:

  • Co-processing is officially validated as a sound and

recommended technology for hazardous and non- hazardous waste management, pop’s related wastes included

  • Co-processing is consolidated as recovery operation in

the waste management hierarchy,

  • International and technical criteria / references are

now available for local legal frames,

  • Minimum standards are now defined, limiting informal

and non-low standard players.
