Looking for Proper Management of Construction Waste

According to the EPA, more than 350 million tons of construction and demolition waste is produced throughout the country each year. This enormous amount of waste has led to the call for construction companies of all sizes to concentrate on the proper disposal and/or recycling of construction waste on their job sites.
Effective waste management in construction is not just a regulatory requirement; it’s a crucial component of sustainable building practices. With the growing appreciation of environmental issues, participants in the construction industry, from contractors to lawmakers, are more and more prioritizing strategies that curtail waste generation, increase recycling and support the circular economy. This shift not only benefits the environment but also delivers economic advantages, as effective waste management can result in reduced project costs, a boost in efficiency and better compliance with regulations.
True, the obligation to reduce waste may seem daunting, but don’t worry.  In recent years, ground-breaking waste management tactics have appeared, stretching from enhanced design practices that stress material reusability to the implementation of advanced recycling technologies. What’s more, the addition of digital tools and data analytics is changing how construction companies manage waste tracking and reduction.
To this end, we have several best practices that will help you boost landfill diversion on your next construction project. Whether you’re in quest of a green building certification or simply want to remain compliant with new policies, here are some tips to help reduce waste on your job site.

First, however, let’s look at precisely what is considered waste in construction.
Construction waste can come in the form of:
  • Construction and demolition debris (e.g., concrete, wood, metal, drywall, etc.)
  • Excess building materials (e.g., bricks, tiles, insulation)
  • Glass (e.g., windows, mirrors and glass insulation)
  • Roofing materials (e.g., shingles, tar paper and roofing felt)
  • Packaging materials (e.g., cardboard, plastic wrap, pallets)
  • Spoiled or unused materials (e.g., damaged pipes, warped lumber, expired adhesives)
  • Hazardous waste (e.g., paint, solvents, asbestos)
Keep in mind that managing and lowering these materials not only helps construction firms shrink their environmental impact, but they also help with observance of regulations as well as jobsite safety.

What are the potential effects of improper construction debris management on health and the environment?
Health risks
  • Inadequate or improper disposal of materials including asbestos, lead, paint and chemicals can result in respiratory illnesses, cancer and other such health concerns.
  • Debris can turn into breeding grounds for vermin such as rats that can transmit diseases.
  • Dust and particles from construction debris can lead to allergies and respiratory concerns.
Safety risks
  • Loose debris can produce injuries for workers, drivers and pedestrians.
  • Flammable materials including wood and solvents can present fire risks.
  • Debris piles can produce unsound circumstances, leading to collapses and injuries.
Environmental impacts
  • Inadequate disposal overloads local landfills that are even now operating at near or full capacity.
  • Debris can pollute water bodies by means of leaking and runoff.
  • Hazardous materials can trickle into the soil, impacting plant life and groundwater.
  • Burning or inappropriate disposal of debris discharges unsafe gases into the atmosphere.
  • Debris can upset ecosystems and injure wildlife.
Okay, we know the WHAT and the WHY, so it’s time to look at HOW we are going to reduce and recycle construction waste.

Set the right goal
Setting just the right goal can be crucial to our success. So, what exactly is the right goal? One that is precise, measurable and realistic. Let’s say you want to run a marathon. You wouldn’t set a goal to run as far as you can, you would set a goal to run precisely 26.2 miles.

Setting construction waste reduction and recycling goals should be identical. Instead of a nonspecific goal to simply cut down on waste on our jobsite, set a goal to reduce waste by a certain amount. For example, if you are getting ready for a LEED-certified building project, your goal would be to recycle 50 percent of construction waste materials from landfill (the percentage changes based on the particular certification level).

Plan based on the specific project
Once you have a goal ready, you can start to plan how you will reach it. Similar to every marathon runner who may have a distinct training routine that works for them, each project or job site has explicit prerequisites and restrictions that must be taken into consideration when creating a construction waste plan.

To produce your site-specific plan, begin by answering a few basic questions:
  • How much space exists for waste and recycling services?
  • What construction and demolition recycling facilities are accessible in the area?
  • What kind of construction waste materials do you think are likely?

Get everyone on board
Once you’ve determined what it is that you need to achieve, it’s time to get the entire team on board. In the construction world, that involves negotiating with vendors, contractors and foremen who are accountable for making certain that everything that can be redirected from the landfill is being redirected. Obviously, there are plenty of moving parts on a construction site, and they all have their own needs. You’ll make the most of construction recycling by arranging your construction site with these specific needs of your waste removal and recycling vendors in mind from the get-go.
One more thing. We’ve often said in previous blogs that communication is a keystone of a successful team. Keeping everyone on the same page is a nonstop process which is why documentation is also essential to success. Maintain good records, communicate and cooperate and your next project will run effortlessly on time and under budget.

Follow established waste management best practices
Conventional best practices employed by most businesses, including reducing waste and recycling, also apply to construction. These consist of:
  • Implementing appropriate material handling and storage procedures to avoid damage. If you have to store specific materials for future use in your project, make sure they are set aside in a safe, weather-protected space to maintain quality.
  • Investing in team education concerning your waste elimination plan and waste reduction practices. Make sure everyone, including subcontractors, knows about sorting requirements, handling techniques and the project’s sustainability goals. Routine “toolbox talks” can support best practices for reducing construction waste.
  • Establishing a system for sorting out recyclable and reusable materials. You could, for example, set up labeled bins for various types of waste, such as metal, wood and plastic. Doing so simplifies the recycling process and makes it a bit easier for people to do their part in reducing construction waste.
     
Choose vendors judiciously
If you are passionate when it comes to your company and its sustainability goals, selecting a vendor carefully will help support your goals and intentions. You need to choose a vendor that is best for how you work best, one that won’t slow you down and can manage the scale of your project. Your vendor has to be in tune with your schedule because it certainly does no one good if they can’t sort through your materials and empty your containers in a timely fashion. Take your time and make inquiries to find the vendor that will best benefit your company and help you achieve your sustainability goals.

Monitor material usage
Continuously keep an eye on your material inventory and track waste streams during the project’s lifespan. Compare delivered quantities versus actual usage and calculate the waste produced by type. This information helps detect inefficiencies, identify major sources of waste and determines the success of your waste reduction strategies. In fact, if you’re into lean construction, implementing tracking lines up with lean construction principles centered on eliminating waste in all forms.


Communicate with suppliers
Building sturdy, collaborative relationships with your material suppliers is a strong yet underutilized strategy for reducing construction waste. This means introducing proactive discussions in advance of orders being placed, looking at ways to align procurement routines with your project’s sustainability objectives. This includes exploring possibilities such as ordering pre-cut materials to precise dimensions or delivered in sizes that reduce off-cuts produced during installation. This way, you are directly cutting back on material waste at the source. Moreover, organizing just-in-time delivery schedules can drastically lessen the amount of material that’s stored on-site. This helps mitigate the risk of damage, theft or spoilage that leads to needless waste.

The conversation needs to extend to packaging, which normally comprises a significant amount of construction site waste. Team up with suppliers to recognize prospects for employing reusable crates or pallets or ask about packaging take-back programs that shift the disposal obligation away from your team.

Employ innovative technologies in waste management
Since construction activities produce significant waste, integrating cutting-edge technology can considerably lessen environmental impacts while boosting project sustainability. Such technologies as Building Information Modeling (BIM) lead to improved project planning and waste reduction by making possible precise material eliminations and better logistics, lessening the chances of over-ordering and surplus materials.

Furthermore, the introduction of smart waste tracking systems has modernized how construction firms oversee their waste. These systems provide real-time data and evaluation, allowing companies to track the waste created, keep an eye on recycling rates and recognize areas for improvement.

In addition, the use of ground-breaking materials, including biodegradable or recyclable construction products, leads to more sustainable practices in the construction industry. For example, innovations in composite materials offer properties such as strength and lower environmental impact, besides being much easier to recycle compared to conventional substances. Technologies like 3D printing also offer substantial promise, leading to a more precise production of components, which reduces waste during the construction phase.



Think about deconstruction rather than demolition
Okay, we’ve discussed various ways to cut back on construction waste. But what about a completely different approach?

Deconstruction is a substitute for demolition, and it is known for being a reuse tactic, according to the U.S. Green Building Council (USBGC). Put simply, deconstruction is selectively taking apart a building, piece by piece, to preserve materials, and do away with waste. These rescued materials are reusable and convertible into important resources that can be sold to construction projects yet to come. Moreover, if you donate the materials received, you can use it as a tax write-off.

Conventional demolition uses deconstruction’s process of removing the high-valued, reusable materials. However, the chief difference between the two is that demolition has a lower chance of recapturing reusable materials because the process is centered on the speed of material disposal to be as efficient as possible.
Keep in mind, too, that deciding on deconstruction before demolition aids more than simply the environment, it helps assist public heath care by cutting back toxic airborne pollutants linked to demolition.

Engage with the community
Explore community engagement opportunities for diverting usable waste. Local non-profits, community workshops, schools or Habitat for Humanity chapters frequently accept donations of excess or reclaimed building materials. This not only diverts waste from landfills but also offers cherished resources to the community and boosts the project’s social responsibility setting.

Final thoughts
Minimizing construction waste is an important part of sustainable construction and conscientious project delivery. By deliberately applying the best practices discussed above, projects can meaningfully lessen their environmental impact. Moreover, these construction waste reduction endeavors often translate into improved efficiency and noticeable cost savings, paving the way for a more sustainable and economically doable future for the building industry.
