Waste presents significant urban and natural environment issues for
governments, industry and the community throughout the world.
Waste disposal in particular, presents several pressing current and
emerging issues:
- having adverse impact on the environment and public health, which can
arise at many points in the "life cycle" of waste. These include pollution
of surface and ground water, air pollution, generation of greenhouse
gases, contamination of land, and noise, odours and other impacts on
local amenity;
- potential impacts making new landfill sites difficult to locate in already
- developed areas and remote locations increasing transport costs and
energy use;
- continued population growth and economic upturn which in turn leads
to more waste and strain on existing and planned facilities, and;
- signalling an ecologically unsustainable depletion of natural resources
used to manufacture products, many of which are used for increasingly
short periods before being disposed.
In NSW (Australia) by example, space for landfill in the Sydney metropolitan area
(producing two thirds of the state's solid waste) will be exhausted within an
estimated 10 years+. The NSW Government target of 60% waste reduction
by the year 2000 will only extend the life of existing landfills a further 8
years or so.
The waste management hierarchy (Figure 1) illustrates a regime of waste
reduction tactics and their relative impact on conservation of resources.
The hierarchy has spawned a number of responses at each level in
formulating new and innovative approaches to waste reduction. Resource
Exchange is one such case, facilitating Re-use, Recycling and Reprocessing
in the 2nd and 3rd levels of the hierarchy.
The Global Presence Resource Exchange
Information System was developed in collaboration with Environmental
Protection Authority (NSW) and
Illawarra Waste Management, successfully piloted and run in the Illawarra
Region since mid 1997. It has since been recognised as the premier
Resource Exchange model for regional exchange operators which is now used in
Australia, New Zealand, United Kingdom and Jamaica.

Resource Exchange works on
the principal that 'one man's trash is another man's treasure'.
Resource
Exchange facilitates the business to business exchange of waste or
unwanted materials.
As well as facilitating exchanges of materials, Resource Exchange also:
- educates seekers and sources of resources and the wider community to
see all materials as resources and seek out new re-use possibilities;
- helps develop new markets for materials that would otherwise go to a landfill
or a less valued use; and
- gathers data on the nature and flow of materials within a community and
potential sources and users of materials.
