How the built environment sector tackles its waste

[edit] Introduction

Concerns about the environment and globally produced waste are rising. A widespread understanding that this isn’t sustainable has led to various sectors looking for ways to address their own waste issues.

As reported by a Wrap study, the built environment sector is the UK’s biggest consumer of natural resources. According to their study, the sector uses 400 million tonnes of material every year, which results in 100 million tonnes of waste being produced. To put this in context, this level of waste contributes over a third of the UK’s total yearly waste amount.

How can such a shocking amount of waste be produced and what remedies can the built environment action to reduce the level of waste?

[edit] Built environment sector waste

As reported by Resource’s Allan Sandilands, lack of media coverage is the main reason for the insufficient public response on the problem of the built environment sector’s waste. Where plastic pollution has been heavily documented in regard to its effects on wildlife, Sandilands notes no such coverage has occurred for the construction industry, which he refers to a the “silent sector”.

Sandilands believes that badly enforced compliance measures, discordant procurement stipulations, and the habit of shifting the responsibility from clients to contractor, are causing the built environment sector to fail in managing waste responsibly.

The built environment sector will only adjust its waste-based behaviour if it gains an understanding of how beneficial recycling and reutilised materials are. But Wrap highlights how the sector is missing out on more than just the benefit of reducing waste levels, showing how tackling construction site waste can help to:

[edit] Things that can be done

So, what actions can be taken? The main way would be to establish a Site Waste Management Plan (SWMP). This plan helps sites to keep track of their waste, as well as outlining how waste material can be reused or recycled where possible.

Although this might sound like a big task, it will be beneficial for the project in the long term. Plus, you can speak to a waste management supplier, in regard to creating a Site Waste Management Plan; they will be able to advise you on the best ways to segregate your waste material, which skips you need, and how to safely dispose of any hazardous materials.

Another way to reduce its waste is for construction companies to keep track of their ordering process and to predict the quantities they might need by looking at previous projects in order to avoid unnecessary materials. Plus, a review of storage facilities can ensure the materials last as long as possible; is your storage site waterproof and secure?

Construction companies should also consider whether off cuts can be used as a substitute for raw materials. Alternatively, explore the option of selling or donating unused materials in the event that you cannot return them.

If reusing or repairing isn’t possible, companies could opt for recycling rather than disposing. If you have an outsourced waste management provider, they will be able to help advise on this. Recycling is obviously a good option for the environment, but it can also save you money on landfill tax.

[edit] Future waste innovation

It looks like the future is going to offer different pathways for the sector to tackle waste issues. For example, according to World Economic Forum there are potential new building materials that would help manage and reduce waste by making use of food excess. In fact, the source reports that some companies have already begun to tap into this resource; the use of mushrooms for creating bricks in a tower construction, building materials made out of corn cobs, wheat, and even banana plants. Pineapple as a leather substitute, fabrics from citrus peels — if these ideas catch on, the issue of construction waste could be combatted hand-in-hand with waste from other sectors.

Reducing waste is an important issue that all sectors, including the built environment need to address. It is the responsibility of the sector to do as much as possible to reduce, reuse, and recycle its materials wherever possible.
