Challenges in Waste Management

Approximately half of the solid waste produced globally is from construction materials. There is an ecological effect of construction materials at every stage of the construction development – production of raw structure materials, manufacturing, conveyance, construction and then the disposal of the waste.

It is more important than ever for governments to keep in mind that the structured environment of the future is highlighting the beginning of a new environmentally conscious era. Governments have to now adapt to the challenges of environmental sustainability, and the building in industry have to evolve with the challenges of low-carbon economies and natural decrease of resource.

If society is to progress to sustainable development, governments can’t continue to rely on landfills to accept the majority of construction waste. Even though there are lots of initiatives to decrease and recycle construction waste, a substantial amount of construction waste still require disposal at public landfill facilities. Landfills however pose a significant threat to societies health and safety.

Planning

Through the planning stage of the construction job, it is imperative to take into consideration what superfluous materials are likely to be produced and then focus on how these excess materials can either be avoided or the material can be diverted through to landfill.

Now it is sensible and proper practice to design a construction waste management strategy. The key objectives of any waste management strategy for construction site ought to be to:

  • Reduce how much waste is generated as part of the job
  • Optimise how much material is sent for reuse, recycling and reprocessing
  • Reduce how much material is sent to landfill

Here are some key elements to consider when planning and implementing a construction waste management strategy:

  1. Waste streams:pinpoint which waste streams are likely to be generated and estimate the expected amounts of material
  2. Focus on waste avoidance:rather than of managing the waste once it has been created, look at methods to avoid producing waste in the first place
  3. Services:choose a suitably experienced waste management contractor who will provide services for the waste streams generated as well as liquid waste disposal
  4. On-site:recognise how the waste management system will work on-site
  5. Clearly allocate and communicate duties:ensure those staff involved with the construction process are understanding of their responsibilities in terms of the construction waste management strategy
  6. Engage and educate employees:be clear about the way in which the different elements of the waste management strategy will be implemented and ensure that the workforce have avenues to provide opinions on what they believe is or isn’t working
  7. Monitor:to ensure the strategy is being implemented, monitor on-site situations and determine factors such as confined space entry and contingencies of that

Some Waste Management Processes

Jobsite Sorting

While operating on the worksite it’s essential to competently recognise and classify materials. This assists in managing the financial feasibility of diverting construction waste to disposal.

Materials may be classified into a number of storage areas. It could be sensible to hire service businesses that specialise in the management of specific jobsite waste types. Contemplate using the minimal number of containers for increased efficiency. This will reduce the number of transportation trips and keep the jobsite clear and free of obstructions.

Tipping

It is essential for the construction management team to recognise the waste potential on arrival at construction and ensure suitable demolition. The facility management strategies will define construction materials that will be accepted. If these materials prove to not be acceptable, they have to be turned away and disposed of in a public sanitary landfill. Ensure you identify the four hazardous waste characteristics of ignitability, reactivity, and toxicity.
