Can You Recycle Quartz Countertops? The Complete Guide

Quartz countertops have become an increasingly popular choice for kitchen and bathroom remodeling projects in recent years. Made from crushed quartz bound together with resin, these countertops are praised for their durability, low maintenance, and stylish appearance. But what happens when it’s time to replace them? Can quartz countertops be recycled? Here is a complete guide on recycling quartz countertops.

What are Quartz Countertops Made of?

To understand if quartz countertops can be recycled, it helps to first look at what they are made of. Quartz countertops consist of:

  • Quartz – This is crushed natural quartzite rock mixed with colored quartz. Natural quartz makes up over 90% of the countertop by weight.
  • Resins – A small amount (around 10%) of polyester or epoxy resins are used to bind the crushed quartz together into a slab.
  • Pigments – Pigments are added to the resin to create the various colors and patterns available.

So in summary, quartz countertops are predominantly made of natural crushed stone bound together by a little resin and color. This composition is important when considering recycling.

Are Quartz Countertops Recyclable?

The good news is yes, quartz countertops are technically recyclable. The high natural quartz content means they can be crushed down and reused in other applications. Here are the key points on recycling quartz countertops:

  • The quartz pieces can be reclaimed and reused in new countertops or other engineered stone products. Recycled quartz is gaining popularity.
  • The resin binders can be separated and used as filler in asphalt or plastics.
  • Pigments may be salvageable for reuse depending on type.

So by breaking down the countertop into its constituent parts, the majority of it can be recycled into new products. Most quartz manufacturers state their countertops are recyclable.

How to Recycle Quartz Countertops

Recycling quartz countertops involves first removing and then breaking down the slabs. Here are the steps:

  • Removal – Carefully detach the countertops from cabinets/walls without damaging large pieces.
  • Transport – Take slabs to a facility for recycling. Manageable sizes are easier to transport.
  • Crushing – Using heavy machinery, crush the slabs into small quartz pieces and powder.
  • Separating – The resin binders are separated from the crushed quartz using water and vibration screens.
  • Reuse – The quartz pieces are dried, sorted and reused in new engineered stone products. Powder may be used for concrete mixes.
  • Recycle Binders – The separated resin powder is recycled, often for asphalt or plastic filler.

So with the right equipment and process, quartz countertops can be broken down and recycled. Facilities specializing in recycling engineered stone are the best option.

Quartz Countertop Recycling Challenges

While quartz countertops are technically recyclable, there are some challenges around reuse and recycling:

  • Limited facilities – There are not many recycling plants focused on engineered stone. Facilities are growing but remain limited.
  • Transportation – Hauling heavy slabs long distances isn’t eco-friendly. Local options are better.
  • Cost – Recycling processing costs mean reused quartz is often more expensive than new.
  • Contamination – If slabs are badly installed/removed, contamination reduces recyclability.
  • Glued slabs – Countertops glued to surfaces are harder to remove and recycle.

So while the quartz material itself is recyclable, the lack of facilities, infrastructure, and higher costs can deter recycling. More recycling plants and lower processing costs could improve this.

Alternatives to Recycling Quartz Countertops

If recycling is not a feasible option, here are some other alternatives to consider:

  • Reuse – Sell or donate removed quartz slabs for use in other projects. This avoids the material going to landfill.
  • Repurpose – Cut slabs down into smaller pieces for use in mosaics, tiles, furniture etc.
  • Resell – Try selling quartz pieces to manufacturers or stone yards where they can be reused.
  • Landfill – As a last resort, dispose of the countertops properly at a landfill. Ensure they are well wrapped to minimize dust.

The best option is always trying to give the quartz a second life through reuse or repurposing before considering landfill disposal.

Is Recycling Quartz Countertops Worthwhile?

This depends on a few factors:

  • If recycling facilities are accessible in your region, recycling is likely the best option.
  • For long-distance transportation, reconsider recycling if high CO2 emissions outweigh the benefits.
  • Reusing or repurposing the slabs locally is often better for the environment than extensive transport.
  • Recycling is worthwhile if it keeps quartz out of landfills and gives the material renewed purpose.

So consider all options, but reuse and recycling locally tend to be the most sustainable approaches. The choice comes down to availability, logistics, and costs in your area.


In summary:

  • Quartz countertops are technically recyclable since they are mostly crushed stone bound with resin.
  • Facilities can separate and reuse the quartz and resin in new products.
  • While recyclable, lack of recycling plants and high costs can deter recycling.
  • Alternatives like reusing locally or repurposing provide environmental benefits too.
  • Consider options in your region and choose the one keeping quartz out of landfills.

With some effort, creativity and the right local options, quartz countertops can often be given a new lease on life through recycling or repurposing. This keeps resources in use and avoids unnecessary waste. The possibilities to recycle quartz are growing with more interest and infrastructure.
