Construction wastes are unwanted materials produced by building construction. This include building materials such as lumber, electrical wiring, brick, concrete and wood as well as waste from site preparation such as tree stumps, dredging materials and rubble. Construction waste may contain asbestos, lead and other hazardous substances. Building waste can be as high as 10 to 15% of the materials, there is a big opportunity to reduce this waste. Many elements of construction waste can be re-used and recycled.
Building materials and other construction wastes like refuse building materials, surplus and hazardous wastes must be properly managed and disposed of to reduce the risk of pollution. Proper waste disposal, recycling, spill prevention, proper material handling and cleanup measures can reduce the potential for contamination of surface or ground water.
Every year around 1000 slips or accident in construction sites results in someone fracturing bones or dislocating joints. These accidents can cause permanent disability and has a huge impact on work and personal life. Many of the incidents are caused by something in the person’s way such as construction materials or waste. Sensible waste management during construction can reduce waste, reduce disposal and transportation cost, save on raw materials and improve safety whilst protecting the environment.
Efficient identification and sorting of materials is important in waste management. Materials may be sorted into a number of containers provided by service companies that specialize in management of construction waste. Waste management companies offer construction sector a number of specific tools and solutions which can help reduce the amount of produced waste, re-use and recycle more materials as possible, make efficient use of resources and save on the cost of waste disposal. They will determine the most effective and safest way to remove and collect construction materials from the site.
Waste management companies provide pre-demolition and refurbishment audits. They give detailed information on what materials can be reclaimed and recycled to reduce the cost and environmental impact of waste. This information can help bring savings by re-using existing materials and earning from selling materials that are not needed.
From small construction projects to large scale development waste management companies can advise on the proper type, size and placement of skip bins to keep the job site cleaner, safer and more efficient. Typical skip bin size ranges from 3 to 9 cubic meter containers. When dumpster is too big for the site dumpster in a bag can be the best waste removal solution. This is perfect for small projects or sites with limited space.
Roll-on roll-off is a cost effective and efficient system for bulk waste removal. This is best suited for commercial and industrial customers who generate large volumes of waste and have the space to store containers on-site. RORO is ideal for dense, bulky, non-compactable materials like timber, wood, concrete, steel, bricks and soil.
Skip bins containing construction waste are collected and transported to diversion facilities to be sorted. Diverted materials are incorporated in new products as recycled materials or processed for reuse. Materials distained for landfills include refuse, contaminated waste materials and materials without commercial value. Waste management is an important part of project development. Efficient and effective waste elimination and reduction maximize resource recovery, reduce waste to landfill and improve environmental sustainability.
