In addition to exploring what you’ll build with and where it comes from, it’s also important to pay close attention to how much you need. Ordering excess material for a project can lead to direct waste through it simply sitting on a site, increased energy and transportation waste by shipping unnecessary goods, and financial waste because you’re buying stuff you don’t need. As well as quantity, also plan for variants of any material—don’t get 12ft planks when 10ft will do. LEED can help with this planning stage through its extensive frame- work. One such credit designed for this is “Construction and Demo- lition Waste Management Planning,” which is required for BD+C: New Construction. Additionally, there are five points available for the “Building Life-Cycle Impact Reduction” credit, which is focused around planning, specifically “by reusing existing building resources or demonstrating a reduction in materials use through life-cycle as- sessment.” On-Site Waste Management for Sustainable Construction Once the planning stage is complete and you’re actually on-site, there are many areas for potential waste generation. A first general step is the creation of a designated waste management area with a waste manage- ment partner. All waste from a site can be funneled here, where trained operatives are able to follow the waste hierarchy, separating out reus- able materials that can go back to the site, recyclable materials that can be sent for processing, and anything that goes to landfill. However, before anything ends up at the designated waste manage- ment area, we should look to the top of our waste reduction hierarchy: reduce. And one way to reduce the wastage of materials is through the improvement of skills. There will always be some slip-ups, of course,

but ensuring you work with a skilled and reliable team can mean a reduction in the amount of materials and items being wasted from mis- cuts, mismeasurement, drops, and more. Additionally, while you should avoid excess material in your planning stage, there will often be some surplus during construction. Explore the opportunities for returning excess or even waste material to sup- pliers. Offcuts can sometimes be sent back and resold for use in other projects, while take back services could mean far less usable waste being sent to the landfill. Finally, packaging can be a real issue, and while many consumers are trying to reduce this type of waste while grocery shopping, the same is not true in the construction industry. Take the time to look for materials and products that come with less packaging — this can help on-site waste and its associated management costs. Like with the planning stage, you can use the LEED framework to help stay on track. Specifically, there is the two-point credit “Construction and Demolition Waste Management,” which outlines strict measures for diverting waste streams or reducing your total waste. Waste Management at End-of-life: Demolition & Deconstruction As mentioned earlier, you should plan for any project’s end-of-life, but it is also worth considering how to reduce waste when you are bringing that end. Around 90 percent of all C&D waste comes from demolition, so reducing it at this point can have a massive impact, whether you’re clearing space for a new construction or just bringing a building down. To do so, look towards deconstruction rather than demolition. This involves stripping a building to salvage its usable materials. It is es- pecially applicable for wood-framed buildings, those with high-value elements, those that are structurally sound, and those with good bricks but bad mortar. Deconstruction not only reduces the amount of waste generated at the end of a building’s life but also creates materials that are redirected into new construction projects (either your own or others) to reduce the amount of raw materials needed, bringing us full circle. Like with the on-site LEED framework, the Construction and Demoli- tion Waste Management credit can help implement the required waste diversion and reuse needed to achieve sustainable construction waste management when bringing down a building. Construction and demolition waste is a major issue, but it can be tack- led by addressing waste points throughout the lifecycle of a building. Planning ahead, good site management, and better demolition tech- niques through the lens of the waste hierarchy can lead to significant reductions and greener, more sustainable construction.
