According to a recent study*, "reduce, reuse and recycle" policies are necessary to control the amount of construction waste, but insufficient resources, lack of standardization, slim profit margins, policy apathy and lack of education on the issues are keeping that from happening.
About half of the solid waste generated worldwide are from building materials. There is an environmental impact of building material at every step of the building process — extraction of raw materials, processing, manufacturing, transportation, construction and finally disposal.
According to the National Association of Home Builders (NAHB) study, an estimated 8,000 lbs. of waste is created from the construction of a 2,000 square foot home. The majority is wood, cardboard, and drywall. Almost all of that waste ends up in landfills.
It is essential for governments and authorities to consider that the built environment of the future is being constructed at the beginning of a new ecological era. Governments must now respond to the challenges of environmental sustainability, and industry must respond to the challenges of low-carbon economies and resource depletion.
If we are to move towards sustainable development, we can no longer rely on reclamation/landfills to accept most of the inert construction waste. Although there are many initiatives to reduce and reuse construction waste, a substantial amount of materials still require disposal, either at public fill reception facilities or at landfills. Landfills also pose a great threat to health and safety.
During the planning phase of the construction project, it is important to understand what excess materials are likely to be generated and then focus on how the generation of those excess materials can either be avoided or the material can be diverted from landfill.
Reducing, reusing and recycling your construction waste can bring many benefits
It is now prudent and good practice to develop a construction waste management plan. The key objectives of any construction waste management plan should be to:
Minimize the amount of waste generated as part of the project
Maximize the amount of material which is sent for reuse, recycling or reprocessing
Minimize the amount of material sent to landfill
Waste streams: identify which waste streams are likely to be generated and estimate the approximate amounts of material
Focus on waste avoidance: instead of managing the waste once it has been generated, look at ways to avoid the generation of that waste in the first place
Services: select an appropriately qualified waste management contractor who will provide services for the waste streams generated and data on waste/recycling generation
On-site: understand how the waste management system will work on-site, including bin placement and access
Clearly assign and communicate responsibilities: ensure that those involved in the construction are aware of their responsibilities in relation to the construction waste management plan
Engage and educate personnel: be clear about how the various elements of the waste management plan will be implemented and ensure personnel have an opportunity to provide feedback on what is/isn’t working
Monitor: to ensure the plan is being implement, monitor on-site
Evaluate: once the project is complete, evaluate your estimates in the plan against the actual data for waste generated and consider feedback from personnel.

Utilizing our Plasmatron as the heart, we add additional hopper and weather protection.
Operation can be carried out by 2 people. Prep and filling is continuous and separation of metals is minimal. System is automated and PCL controlled for optimum performance. Full training is provided by WTTEC. The training personal will be on-site for the first 4 weeks to insure proper performance, training and guidance.
There are no moving parts and requires only the removal of the ash when requires. Scheduled maintenance will be carried out by WTTEC personal for the first two years.
Portable: Moved from site to site when finished. 2 trucks.
Ceramic ash that can be used to augment cement for roads, sidewalks and curbs. Is inert so can even be used for back-fill.
Approximately 1000 KGs of waste reduces to 20 KGs of ash. (dependent on feed-stock)
Construction waste to include ALL:
·Wood : ALL (bare, chip, planks, treated, flooring etc.) ·Drywall
·Left over paint
·Plastics : ALL
·Asphalt shingles and roofing
