Let’s delve deep and see what exactly each of these companies offers to their clients:

1. Prairie Material

Prairie Material is a managed producer of ready-made concrete mix and aggregate materials with three divisions located in the Midwest. Prairie has been providing top-quality products for over 75 years now, making them one of the most reliable materials suppliers in the region.

Sustainability Efforts

Prairie Material has taken sustainability very seriously as they are producing aggregate materials on a large scale.

They work closely with the local government to ensure they comply with all the recent regulations. In addition, the mining operations are conducted in an environmentally safe manner to ensure that the ecological diversity surrounding the location is well protected.

Unlike other companies that just have a sustainable producer tag on their site, Prairie has gone well beyond that and actively invested in R&D to develop technologies that help them improve their efficiency while preserving biodiversity at the same time.

They realize that they don’t have to reinvent the wheel here. By just upping their overall operational efficiency, they can reduce emissions and become more of a sustainable materials producer.

While concrete construction can never be as eco-friendly as rammed earth construction, it is good to see such companies have put their hand up to ensure such construction is done with materials produced in an eco-friendly manner.

2. Chicago Green Insulation

Tom Decker is the mastermind behind Chicago Green Insulation, a company solely focused on providing spray foam insulation services to homeowners. They are the number 1 insulation providers in the Chicago area, giving top-notch service. Not only that, but they claim to be the cheapest contractors in the region.

Sustainability Efforts

The “Green” in Chicago Green Insulation refers to the commitment made by the company to ensure an eco-friendly service. This is because such services are notorious in regard to their environmental impact.

It is no secret that foam insulation emits harmful gases, and options like sheep’s wool insulation are a better choice. But this can be limited when the curing time is reduced due to proper product preparation.

The company backs itself on preparing the foam on site and has the perfect mixing ratio helping them achieve a product that cures quickly without leaving any trace of harmful odors.

Some insulation work is needed, not just in a conventional home but also in an adobe or a cob building. This is why the company has focused on insulation work and hopes to serve most of the Illinois area.

3. USG

Formed over 100 years ago in 1902, USG is taking a major chunk of the market share in wallboard and gypsum products in the United States. Their products have been used in structures like the Burj Khalifa in Dubai and the iconic Freedom Tower in New York.

Sustainability Efforts

Over the years, USG has taken extreme measures to reduce energy usage. Between 2005 and 2020, their energy usage (per unit of production) has reduced by 20%. Landfill waste, too, has decreased by 29% in the last decade.

USG is focused on making a huge leap in sustainability by 2030. But it’s not just the efficiency they are looking at. The current products too reflect the policy that the company follows. For example, some of the panels they build that are made from recycled materials.

4. The AZEK Company

It also has a state-of-the-art Polyethylene recycling center, and they are actively introducing products built using recycled materials.

In 2023, Green Builder Media recognized AZEK’s efforts and awarded their products (TimberTech and AZEK Exteriors Captivate) as the Sustainable products of the year.

5. Z Modular

Z Modular is a steel modular construction company specializing in designing, manufacturing, and constructing high-quality, cost-effective buildings using the VectorBloc construction system. This is a system that enables precise alignment and secures connections between modules.

Since modules are manufactured in a controlled factory environment, Z Modular can maintain strict quality standards. This ensures that the overall product is consistent in quality and adheres to the building codes.

Sustainability Efforts – Recycled Steel Building

By using Steel as the main building material, the company promotes sustainability, as it is highly recyclable and has a low environmental impact. The VectorBlocs are produced using 100% recycled steel from nearby foundries that process steel.

Additionally, the modular construction process generates less waste, reduces construction site disturbance, and allows for efficient use of materials. At the end of its life, any building constructed like this can have all its major materials recycled in a factory setting.

6. Bulley & Andrews

8. Wight & Company

With over 80 years of experience, Wight & Company is next on my list as one of the construction & design firms actively building sustainable projects in the Midwest region.

They are highly regarded for their creative and sustainable designs over various sectors and follow a unique project delivery method called “Design-Bid-Build.”

Sustainability Efforts

The company ensures the structure is sustainable and energy efficient from the design level. This is why Wight & Company is bagging big contracts to build sustainable structures. One good example is the firm getting selected through an international competition to design a sustainable campus for autistic students in Qatar.

But the project that really gave the desired direction towards sustainability was the BEQ (Bachelor Enlisted Quarters) at Great Lakes Naval Training Station.

The Navy employed the company and made their intentions clear on winning a President’s award for sustainability through this project. This was a pilot project in the USGBC’s Sustainable showcase and the first LEED-certified building in the States.

9. Negwer Materials

Sustainability Efforts

Under their Design/Build agreement, a single entity looks at the entire operation. The initial construction is started without a detailed design to save time. This agreement is an attractive option for those under time pressure.

ICI also offers general contracting and management services to its clients.

Sustainability Efforts

At ICI, sustainability is at the forefront of its operations. ICI’s team comprises 6 LEED Accredited Professionals and 30 SWPPP Certified members working towards incorporating eco-friendly practices into their projects.

Trim-Tex Drywall Products was founded by Joseph Koenig Sr. in 1969. Since then, Trim-Tex has come a long way from its humble beginnings in a 1,500 sq. ft. space to operating in its current facility in Lincolnwood, IL, which is more than 150 times bigger.

Initially, it produced just two different sizes of J Beads but has since expanded its product range to offer more than 200 innovative drywall solutions.

Founded in 2003 by Guy DeDoe, Andy Stephens, and Francisco Morales, Tangent Materials has become a leader in the plastic lumber industry. They initially targeted an underserviced market segment and then expanded from a modest 20,000 sq. ft facility to a 600,000 sq. ft. facility.

The company has 40 production lines and employs over 500 people. Tangent’s constant efforts led to the development of their patented woodgrain dimensional lumber in 2016. This was a game-changing product as it closely mimicked the appearance of real hardwood.

Sustainability Efforts

Tangent takes environmental responsibility seriously, diverting millions of pounds of post-consumer and post-industrial plastic waste from landfills each year.

Recycled Plastic Construction: By recycling 15,000 tons of plastic waste each year, Tangent continues to deliver durable, eco-friendly products, thus solidifying its position as a category leader.

Sustainability Efforts

Bamboo in itself is quite a sustainable product and is widely known as the “green steel” of the 21st century. Since some jurisdictions are reluctant to approve extremely cheap & sustainable structures like earthbag buildings, more people are looking towards bamboo as their preferred choice of building material.

Final Takeaway

This list of 16 sustainable companies from Illinois highlights how more construction companies take sustainability seriously.

One good thing to notice is these companies are doing much better than conventional companies that overlook sustainable practices to focus on their profits.

As people become increasingly aware of their environment, more big projects are going green and hiring companies that provide services and materials that help them achieve their sustainability goals.

This is important because, for ages, the idea of a green structure was as simple as an adobe building. But since modern methods are used more, big companies must take the path of sustainability to protect our environment for future generations.
