The business case for reducing construction waste is proven to save you time and boost your profits.
Seven killer facts and the key questions to ask
There are two key reasons to adopt an effective SWMP – better project management and bigger profits.
The killer facts
- Storage and ordering – Of the 400m tonnes of materials delivered to UK sites annually, 60m tonnes go straight to tip due to over-ordering, damage resulting from poor storage or inappropriate ordering (UK Green Building Council).
- Reputation – Reducing waste is an effective way of demonstrating construction efficiency
- Sustainability – Reducing site waste will help achieve BREEAM and other sustainability assessment targets. Most UK local authorities have adopted planning policies requiring minimum BREEAM or Code for Sustainable Homes standards.
- Environmental Impact – Up to 58% of the carbon associated with waste can be saved through an effective reduction and management programme
- Waste management and disposal cost the industry the equivalent of 30% of pre-tax profits
- Landfill tax will continue to increase (currently £84.40/tonne). Reducing waste costs will result in improved profitability
- Money – the cost of waste can be over £1,000/skip when you include the cost of wasted materials and labour.
An SWMP may be required for BREEAM assessments or by the local planning authority.
A plan should be prepared by the client/consultant before construction begins. It should describe how materials will be managed efficiently and disposed of legally and explain how the re-use and recycling of materials will be maximised. This involves estimating how much of each type of waste is likely to be produced; the proportion to be re-used or recycled on-site, or removed for re-use, recycling, recovery or disposal.
Your SWMP and the questions to ask:
1. Do you know from the outset how much waste your project will produce and what the potential waste disposal costs will be?
The true cost of waste, including the purchase cost of unused materials, their transport and handling, has been measured at over 15 times skip hire costs.
A key factor in getting on-site waste reduced is to get the specification spot-on from the very start. Superglass has a dedicated specifications team who work with architects and housebuilders to understand their project and ensure they order the right specifications and quantities of product.
2. Have you considered off-site manufacturing or modular building?
This is growing fast – if entire panels such as walls/floors or modules such as bathrooms are brought on-site to be assembled or dropped into place there, time savings of up to 50% can be achieved along with huge waste reduction.
3. Are you measuring the waste arising on your site?
Case studies show that measuring waste can lead to savings of 3% of build costs and up to 20% of materials on site
4. Do you know where your waste comes from?
It may be from:
- The way you handled and used materials on-site
- Material storage
- Over-ordering materials
- Delivery of materials to site
All these contribute to wastage on-site and it’s where a SWMP comes in. One of the greatest areas of potential for reducing site-waste is through project design and specification. The innovative and versatile Superglass range means that very exacting and complicated specifications can be tailored to, either from the extensive array of product options in the core range or via non-standard product.
The latter makes up a substantial amount of Superglass business. So while, unlike other building materials, insulation is not easily recycled on site, Superglass’ Technical Team makes it easier to get the specification and order right resulting in little or no on–site waste to recycle at all.
5. Are you separating wastes on site?
Recyclate value is higher for wastes separated at source than for most mixed wastes
Planning successful waste reduction can enable bid managers to reduce tender prices when confident that lower waste allowances can be achieved, part of this is knowing you have high levels of support from supply partners. Superglass is flexible when it comes to volume and on-site delivery.
