We are committed to send zero non-hazardous waste to landfill by 2015. For us, this is not just an environmental imperative, but a valuable efficiency driver in a competitive market.
We are proud to report that the absolute volume of waste we produce declined in 2012. This reflects the determined efforts across our operations to cut costs and protect the environment, including how we engage subcontractors on the issue.
Waste management in the Middle East and North Africa
The principle of reduce, reuse, recycle is fairly new throughout the Middle East and North Africa (MENA), and recycling infrastructure is generally in its infancy. Carillion is trying to positively influence this by starting its own projects.
In Oman, a partnership with local compost manufacturer, Kala Compost, has seen more than 2,700m3 of timber waste diverted from landfill since the start of 2012, for eventual use in gardens throughout the country. Around 95% of the timber waste generated by Carillion’s contracts in Oman is now recycled in this way, compared to 45% in 2011.
At another contract in Abu Dhabi, the reuse of materials has been taken a step further, with the construction team choosing to build their site office using waste materials that would otherwise have been thrown away. This reduced the need for raw materials, lowered the carbon emissions of the contract, and saved around 18,000 AED (roughly £3,000).
We are vigilant about optimising the materials we need for each contract, choosing recycled and/or recyclable products where feasible. We have requirements for subcontractors to report on waste generated and percentages diverted from landfill. Furthermore, in 2012 we:
- continued to roll out a Waste Management Plan for every site
- improved how we collect waste data through our web-based tool, Capture
- tailored our approach to each contract, including calculating requirements carefully to avoid over ordering
- increased focus on designing out waste across our contracts
- used the Waste and Resources Action Plan (WRAP) Net Waste Tool in the UK
- continued to move towards off-site manufacturing and standardisation where possible
- set up recycling centres on all contract sites in the Middle East
- reused office furniture across our UK estate
- reviewed our waste suppliers across our construction and services contracts, selecting those that are committed to helping us achieve our zero waste to landfill target.
Over the year, our focus was at the top end of the waste hierarchy as we trialled innovative ways of capturing value from waste. For example, in the UK our contract on the A487 road made use of rock extracted from road widening to construct retaining walls, or for community projects like local footpath improvement.
Reusing crushed concrete at Sellafield
Carillion discovered a substantial layer of crushed concrete over a temporary storage area at the Sellafield site in Cumbria, UK, in 2012. Following discussion with the client, it was agreed that the 25,000 tonnes of material could be reused by the team as a capping layer for the vehicle tracks associated with the Outer Perimeter Security Zone (OPSZ) project.
The benefits included cost savings on first generation materials, transport and disposal, 3,000 fewer lorry movements and a reduced carbon footprint.
“This is a fantastic example of the project team ‘thinking outside the box’, driving an idea to conclusion and in the process saving time and money.”Ian Rae, Senior Project Manager, Sellafield
Going forward, as well as streamlining our efforts towards zero waste to landfill, we will be exploring how we can maximise value from waste – rethinking how we view waste as a commodity and resource, which is vital to our bottom line.
