DRYWALL
Drywall — also known as wallboard, plasterboard, gypsum board. Drywall is made from gypsum, which can be mined, recycled, or synthetically produced from coal waste. Synthetic gypsum may contain mercury, posing health risks like kidney damage and neurological issues.
Facing materials include paper, fiberglass, aluminum foil, or vinyl. Vinyl coatings can release plasticizers linked to hormone disruption.
Health risks are associated with mold growth. That is why drywall is treated with biocides, which may cause allergies, respiratory issues, and hormone disruption, especially for children and sensitive groups.
Cutting and sanding generate fine gypsum dust, leading to eye, skin, and respiratory irritation — prolonged exposure may contribute to asthma and lung diseases.
Drywall production is energy-intensive, and 10% of materials become waste in construction. Using recycled drywall and optimizing installation can help reduce waste and environmental harm.

Priority of choice
Best choice
Good alternatives
Less recommended / Better to avoid
Natural gypsum drywall with post-consumer recycled content
Natural gypsum drywall without recycled content
Synthetic gypsum drywall (especially when there is a lack of transparency regarding its source)
Tips for healthier choice
- Look for drywall with post-consumer recycled content when possible.
- Avoid synthetic gypsum-based drywall due to potential mercury contamination and environmental concerns.
- Avoid mold-resistant drywall unless necessary (e.g., in bathrooms), as it contains biocides that may be hazardous.
- For moisture-prone areas, choose non-paper-faced drywall to prevent mold growth.
- Accurately calculate the required amount to minimize waste and avoid excessive waste generation.
- If cutting or sanding drywall, wear a properly fitted respirator and use dust control measures to limit exposure to fine gypsum dust.
- Consider future recycling opportunities, especially in regions where drywall cut-offs can be collected and reprocessed into new products.
