Quartz countertops have become increasingly popular in recent years as a stylish, durable, and low-maintenance option for kitchen and bathroom remodeling projects. But with growing environmental awareness, many homeowners are asking: are quartz countertops actually an eco-friendly choice?
What is Quartz?
Quartz is a mineral that is found abundantly in nature. It is composed of silicon and oxygen atoms and is one of the most common minerals on Earth. In countertops, quartz is combined with resins and pigments and formed into slabs using heat and pressure. These slabs are then cut to size and installed as countertops.
The key differences between natural quartz and engineered quartz countertops are:
- Natural quartz is extracted from the earth and used as-is, with minimal processing involved. It maintains its natural aesthetic.
- Engineered quartz combines ground quartz with polymers and pigments. It is engineered for improved flexural strength, stain-resistance, and consistency of color and pattern.
So in summary, quartz countertops contain abundant natural quartz but are engineered for functional improvements. Now let’s look at why they are an eco-friendly option.
Why Quartz Countertops Are Eco-Friendly
There are several reasons why quartz counters can be considered an environmentally sustainable choice:
1. Made from abundant natural material
Since quartz is one of the most plentiful minerals on Earth, using it for countertops is an ecologically sound choice. Quartz counters contain about 90% ground quartz, bound together by polymers and resin. So the primary component is abundantly available in nature, reducing the need for scarce resources.
2. Contains recycled content
Many quartz brands tout recycled glass or recycled polymer content of up to 20% in their slabs. By incorporating recycled materials, manufacturers reduce the consumption of new resources and keep waste out of landfills.
3. Durable and long-lasting
With strength and scratch-resistance exceeding that of granite, quartz counters can withstand years of wear and tear while retaining their beauty. Their longevity means fewer replacements over time, reducing waste and environmental impact.
4. Requires less energy and water to produce
The manufacturing process for quartz counters uses less energy and water compared to other natural stone countertops. Quartz does not require complex cutting, polishing, and sealing needed for materials like granite and marble.
5. Low maintenance
Since quartz resists stains, scratches, and heat damage, routine maintenance is minimal compared to other countertops. Less need for harsh cleaners, sealants, and polishing compounds benefits the environment.
6. Mostly non-porous
With very low porosity, quartz does not require regular sealing like granite, marble, and other natural stone. This means fewer chemicals penetrating the material over its lifetime.
7. Can be locally sourced
Many quartz manufacturers have facilities in the United States. Opting for a locally produced quartz countertop means lower transportation miles and fuel use compared to imported natural stone.
How Sustainable is Quartz Countertop Production?
While quartz counters utilize an abundant natural resource and contain recycled materials, some aspects of their production have raised sustainability concerns:
- Resin binders – The polymers that bind quartz particles contain petroleum-derived ingredients. These resins make up about 10% of a quartz slab.
- Energy-intensive manufacturing – High heat and pressure are used to produce quartz slabs, consuming significant energy. Some manufacturers are seeking alternative energy sources like solar and wind.
- Air quality – Cutting and polishing quartz can release crystalline silica dust, affecting air quality in fabrication facilities. Proper dust-collection systems are critical.
- Transportation – As a manufactured product, quartz counters still must be transported from factories to distributors to installation sites. Locally sourced materials reduce fuel emissions.
So while quartz achieves better sustainability metrics compared to natural stone overall, manufacturers continue working to improve the eco-friendliness of production.
How Quartz Stacks Up to Other Countertop Materials
Comparing the overall environmental impacts of quartz versus other leading countertop materials further demonstrates its strengths:
Quartz vs. Granite Countertops
- Granite is natural rather than engineered, but mining granite has ecological impacts and depletes limited natural resources.
- Quartz contains more recycled content than granite.
- Quartz requires less energy for fabrication and transportation compared to heavy granite.
- Maintenance and longevity favor quartz. Granite requires regular sealing and polishing to maintain its look.
Quartz vs. Marble Countertops
- Like granite, marble is a natural stone that is mined, depleting resources. Transport also has environmental impacts.
- Quartz is more durable, stain-resistant, and low-maintenance than marble.
- Marble is porous and needs frequent sealing, increasing chemical usage over its lifetime.
Quartz vs. Laminate Countertops
- Laminate counters contain petroleum-derived resins that off-gas VOCs and cannot be recycled.
- Quartz contains natural quartz and recycled materials, creating a more eco-friendly surface.
- Laminate has a much shorter lifespan, ending up in landfills sooner and consuming more long-term resources.
Quartz vs. Concrete Countertops
- Concrete counters are considered quite eco-friendly since they use abundant natural ingredients like stone and sand.
- However, concrete requires significant energy and water for production. Off-gassing of concrete dust is also a concern.
- Quartz and concrete have more similarities in sustainability than differences. But quartz edges out concrete in durability and longevity.
Quartz vs. Solid Surface Countertops
- Solid surfaces like Corian contain high levels of petroleum-derived acrylic resins, while quartz relies primarily on an abundant natural material.
- Solid surface counters cannot be recycled. Thermoset resins result in waste. Quartz contains some recycled content.
- In terms of durability and longevity, quartz again is the winner over solid surface materials.
So while no countertop offers perfect sustainability, quartz balances durability, low maintenance, and eco-friendly sourcing very well compared to leading alternatives. The percentage of recycled content can also be maximized by choosing the right quartz brand and color patterns.
How to Pick an Eco-Friendly Quartz Brand
For the most environmentally responsible quartz purchase, look for specifics on recycled content, manufacturing sustainability initiatives, and corporate environmental values when selecting a brand:
- Caesarstone – Up to 20% recycled content. Uses bio-based epoxy. Designed for low waste production. ISO 14001 certified.
