Quartz countertops have become increasingly popular in recent years as an attractive, durable, and low-maintenance option for kitchen and bathroom remodeling projects. However, some homeowners have concerns about the potential environmental impacts of choosing quartz. In this article, we’ll examine the key considerations around quartz countertops and sustainability.
What is Quartz?
Quartz countertops, sometimes referred to as engineered stone, are made from crushed quartz combined with resins and pigments. Quartz is an abundant mineral found in nature, while the resins bind the material together and allow it to be molded into countertops.
The main environmental advantages of quartz over natural stone are:
- Quartz is readily available and requires less energy-intensive mining and processing.
- Quartz countertops have very little waste during fabrication compared to natural stone.
- Quartz is non-porous and does not require sealants that can off-gas VOCs (volatile organic compounds).
Manufacturing Process and Raw Materials
The biggest environmental concern around quartz counters is the use of resin adhesives during manufacturing. Most quartz uses a polyester resin made from petroleum. Some brands have introduced greener bio-based resins made from plants, but they are not yet widely used.
The other key component is crushed quartz. Quartz crystals are abundant in nature, but mining and processing does involve energy use and some waste. Responsible sourcing of materials can minimize the impacts.
Transportation and Carbon Emissions
As an engineered product, quartz counters are manufactured in select locations and shipped to installation sites. This transportation accounts for greenhouse gas emissions. However, quartz is lighter weight compared to natural stone, reducing emissions during shipping.
Local sourcing of materials and manufacturing can reduce transportation impacts. Many top brands do manufacture in multiple locations worldwide.
Durability and Lifespan
An important sustainability consideration for any countertop is its expected lifespan before replacement is needed.
Quartz counters are highly durable and typically last 15-20 years or longer with proper care. The long lifespan avoids the environmental impacts of frequent replacement, giving quartz an advantage over less durable options.
Maintenance and Cleaning Requirements
Quartz requires very little maintenance compared to natural stone counters. It does not need periodic sealing and is stain resistant. This reduces the need for harsh cleaning chemicals over the lifespan of the counters.
Simple mild soap and water is all that is required for cleaning quartz. Some “green” plant-based quartz cleaners are also available.
Recycling and End-of-Life
There are currently limited options for recycling quartz countertops at end-of-life, though some initiatives are emerging.
The bulk of a quartz counter is crushed stone that can potentially be re-used as construction aggregate. The resins are more difficult to recycle. Some manufacturers will take back scraps for re-use.
More recycling options may develop in future as quartz use expands. But for now, recyclability is a limitation.
Is Quartz a Sustainable Choice Overall?
There are certainly some environmental trade-offs with quartz counters compared to natural stone or other materials. But quartz remains a reasonably green option when factoring in all sustainability considerations.
Compared to many materials, quartz uses less energy overall, creates less waste during fabrication, and has exceptional durability. Maintenance and performance are where quartz really shines for eco-friendly living.
Consumers can also choose options like bio-resins and recycled content when available. And local sourcing and manufacturing helps minimize transport impacts. With some careful selection, quartz can be a very sustainable choice that also provides great functionality.
Questions and Answers About Quartz Countertops and the Environment
Is quartz eco-friendly?
Quartz can be an eco-friendly option compared to many other countertop materials due to its durability, low maintenance, and natural quartz content. Manufacturers are also improving sustainability by using alternative resins and recycled materials.
Is quartz harmful to the environment?
Quartz is not considered inherently harmful. Concerns are mainly around mining impacts, resins used in manufacturing, and lack of recycling options. But quartz performs better than many materials on measures like energy use and longevity. Responsible sourcing and production help minimize environmental harm.
Is quartz better than granite environmentally?
Quartz tends to have less environmental impact than granite in most cases. Granite quarrying and fabrication create more waste. Quartz has higher durability and stain resistance, reducing maintenance needs. And lighter weight quartz reduces transportation emissions.
Should you avoid quartz for environmental reasons?
There is no need to completely avoid quartz if you are concerned about the environment. Look for options with recycled content or greener resins. And consider other green aspects like manufacturer practices, transportation distance, and an installer who reduces job-site waste.
Does quartz off-gas VOC chemicals?
Pure natural quartz does not off-gas VOCs. During manufacturing though, resin adhesives used to bind the crushed quartz can contain VOCs. Most off-gassing occurs prior to installation. Letting quartz counters air out before use can further minimize exposure to any VOCs in adhesives.
Can you recycle quartz countertops?
There are a few options emerging to recycle quartz counters, though these are not yet widely available. Some manufacturers will take back scrap for use in new product. And recycled crushed quartz can potentially be used for construction materials. More recycling initiatives are needed to improve the eco-profile of quartz.
Conclusion
With mindful material sourcing and manufacturing, quartz counters can be a smart eco-choice that also offers many consumer benefits like durability, low maintenance, and stylish aesthetics.
Quartz is not impact-free, but compares well to many other materials on overall sustainability. Ongoing innovations by leading manufacturers are also improving the environmental profile of quartz surfacing.
Choosing locally produced quartz from companies committed to sustainability helps minimize impacts. And proper use and care keeps quartz counters out of landfills for many years. For homeowners who want a high-performing, low-maintenance surface, quartz offers a reasonably green option.
