Waste Processing
Our approach is focussed around creating a one-stop waste management facility that processes all non-toxic waste streams.
The 'modules' within this facility will include:
Construction & Demolition Waste
The C.C.R. Facility processes the Demolition Waste Stream in an integrated process over 3 processing tiers: -
Tier 1 Pre Dressing – Minor size reduction and purification,
Tier 2 Crushing - Major size reduction and further purification,
Tier 3 Screening – Crushed product is screened into various size grading ready for reprocessing or to appropriate reuse applications.
The C.C.R Facility complete unit involves, electric generator, crusher, screening unit, stockpile conveyors, ancillary equipment (front end loaders, crawler mounted excavators, concrete breakers & pulverizes), and skilled operators.
Tier 1:
Pre Dressing, a concrete breaker and pulveriser on an excavator are used to reduce in size concrete blocks and remove long lengths of steel reinforcement.
Tier 2:
Before crushing the feedstock; (1) a loading grizzly conveyor discharges soil etc, (2) contamination such as timber is removed manually as it passes the picking area
Tier 3:
Before screening a magnetic conveyor removes any steel. The screening plant then separates product into nominal fines and 20mm, 40mm and 70mm grading.
Recycled Crushed Concrete Uses:
Demolition Waste; Concrete, Brick, Stone and asphalt is crushed and recycled as an alternative to crushed rock. Its uses include Hard Standing, Gravel Roads and as a Road Making Material.
Recycled Organic Waste
This is a generic term for products derived from organic materials, including garden and food waste from households and businesses. Recycled Organics products are produced using biological processes, and include mulches and solid or liquid soil conditioners and fertilizers. Recycled Organics products typically contain numerous beneficial micro-organisms and plant nutrients that can; significantly improve soil and plant health; reduce the need for chemical fertilizers, pesticides and herbicides; and reduce water usage and costs. Mulch products can be used to converse water and suppress weeds, and composted mulches also provide soil conditioning benefits.
Composted products are produced from a process whereby organic materials are microbiologically transformed under aerobic conditions for a period of not less than 6 weeks, which includes a pasteurisation phase.
In-vessel composting technology provides optimum pasteurisation conditions for naturally occurring micro-organisms to convert organic waste materials into rich organic soil additives, destroying potentially harmful micro-organisms and weed seeds in the process.
Biosolids
Also known as sewage sludge, it is the solid, semi-solid or slurry material derived from biological wastewater treatment after dewatering. A typical wastewater treatment plant consists of screening coarse materials, grit removal, biological nitrification and denitrification, BOD reduction as well as phosphorus reduction by chemical treatment. Waste activated sludge and the sludge resulting from the chemical treatment are aerobically digested and dewatered in a centrifuge.
Biosolids correctly added to other organic materials, blended, composted and screened will produce excellent products high in nutrients and water-holding capacity for use in agricultural, horticultural and general urban applications as well as land rehabilitation and soil amendment. In a ‘one-stop’ waste facility these organics are utilised within the waste city to produce vaue-added products.
Commercial & Domestic Waste
This operation targets the recovery of ‘Commercial and Household Packaging’ waste (Metal and Aluminium Cans, Plastic Bottles and Containers, Glass Bottles, Paper and Cardboard) for sale or further Down Stream Value Adding.
The MRF (Material Recovery Facility) operations sort out the individual waste material streams and pass on the Plastics Stream to the in tandem configured VIVA (Vertically Integrated Value Adding) facility for purifying and processing to high value plastics recyclates and composites compounds for selected products.
Specialised pick up and delivery systems bring commercial and domestic waste materials to various recycling processing options. Technology includes GPS tracking, in-vehicle visual monitors, computerised measuring and weighing systems and quality control procedures. On-site separation vessels and methodology is included in this service.
