Waste reduction final report -4 - Test Input

Setting targets for the recycling of specific building material wastes
The recycling of specific building materials is to be promoted over the next decade,
especially when taking into account regional variations in recycling infrastructure. The
recycling rates by 2010 (the weight of recycled versus that of specific building material
wastes occurring at the construction site), is listed in the table below:
Concrete (including reinforced)
Timber
Asphalt concrete
95%
Achieving these recycling rates will require
1. Adequate facilities for recycling
2. Development of technology to reduce costs of recycling
3. Increase use of recycled products and materials
This will be supported through taxes and loans. Municipalities should take measures to
develop adequate recycling infrastructure for specific building material wastes in each region.
Specific guidance provided for each of concrete (recycled aggregates and sands), wood waste
(panel board production, fuel, mulch), asphalt concrete (hot & cold mix recycling, road subbase,
capping etc). Other materials such as plastics and plasterboard should also be focussed
upon in terms of technological and financial development to promote recycling.
Promoting the use of recycled materials
Materials and products separated for recycling need to have end uses. This requires the
development of good quality recycled products that are safe and durable. There are a variety
of roles for relevant people. Manufacturers of building materials should try to increase the
recycled content of their products. Designers need to design in the use of reclaimed and
recycled building materials. This should be reinforced through the procurement of building
materials. Contractors should also maximise the use of recycled products and materials.
Waste and recycling contractors need to produce stable and good quality recycled materials.
The Government shall encourage research and development, provision of guidance and case
studies, quality standards, and standardization necessary for the promotion of recycled
materials. Municipalities are required to develop local measures that align with government
policy. The Government should also lead by example in public procurement (in line with law
No. 100, 2000).
Specifically, in the procurement of recycled aggregates regardless of the cost, providing they
are fit for purpose and produced within 40 km from the relevant site, except for the cases
when by-products occurred at construction sites take precedence. In procurement of road
materials where heated asphalt mixture is available through recycling asphalt concrete, within
40 km and 1.5 hours transport from the relevant site, a principle to use the heated asphalt
mixture no matter of cost, regardless of cost, providing they are fit for purpose. In terms of
timber formwork (shuttering), we shall promote using recycled wooden boards. Also
promoted for use in publicly procured projects is mulch (derived from building waste).
Separate dismantling of specific building material wastes for preserving environment
A greater understanding of the best ways to recycle building materials will be developed.
This includes energy for waste, impact on the environment and associated emissions.
Everyone in the supply chain should consider the environment and co-operate to achieve the
