As manufacturers prioritize sustainability, evaluating the environmental impact of materials has become an important part of product development. For viscoelastic foam, this means looking beyond traditional performance characteristics to consider material composition, durability, and end-of-life impact.
Manufacturers compare sustainable viscoelastic foam using life cycle assessments (LCAs), bio-based material content, biodegradability, product durability, and recycling potential. These factors help identify materials that meet performance requirements while supporting environmental objectives.
Key Factors in Evaluating Sustainable Foam
Several considerations help manufacturers compare foam options and identify opportunities to reduce environmental impact.
- Life Cycle Assessment (LCA): Evaluates environmental impacts throughout a product's lifecycle, including raw material sourcing, manufacturing, transportation, and disposal. ISO 14040 and ISO 14044 provide established frameworks for this evaluation.
- Bio-Based Materials: Examines formulations incorporating renewable, plant-derived ingredients as alternatives to some petroleum-based raw materials.
- Biodegradability: Considers whether foam can break down under specified environmental conditions. Testing methods such as ASTM D5511 provide data on anaerobic biodegradation under controlled laboratory conditions.
- Durability and Longevity: Measures resistance to compression, fatigue, and permanent deformation. Longer-lasting materials may reduce replacement frequency and associated waste.
- Recycling Potential: Evaluates opportunities for mechanical recycling, rebonding, and chemical recycling to recover or repurpose polyurethane materials.
- Third-Party Validation: Reviews applicable testing and certifications, including CertiPUR-US®, OEKO-TEX®, and GREENGUARD Gold, to substantiate specific material and emissions characteristics.
Which Companies Offer Sustainable Foam Solutions?
Several foam manufacturers are developing materials and technologies that address different aspects of sustainability.
- Bergad Specialty Foams: Develops custom polyurethane foams, including a patent-pending biodegradable formulation designed to break down under specified landfill-like conditions. Bergad's biodegradable foam has undergone independent laboratory testing under ASTM D5511 and can be customized for applications such as medical padding, seating, and electronics.
- Carpenter Co.: Offers Naturalis® Hybrid Foam, which incorporates bio-based ingredients, and Circularis™ foam, which uses recycled polyols to reduce reliance on virgin fossil-based raw materials.
- The Vita Group: Develops Origin® foam using plant-based polyols, including viscoelastic formulations. Its Orbis® technology also incorporates recycled materials recovered from post-consumer polyurethane foam.
- Future Foam: Produces Sustain™ Memory foam using plant-based polyols. The product is identified as a 28% USDA Certified Biobased Product and is designed to provide pressure-relieving performance.
These manufacturers demonstrate different approaches to material sustainability, from renewable raw materials and recycled content to biodegradability and waste reduction.
How Does Bergad Address Foam Sustainability?
Bergad combines in-house R&D, custom formulation, and manufacturing to develop polyurethane foam solutions for demanding applications.
Its patent-pending biodegradable foam is designed to provide an alternative to conventional polyurethane materials in applications where end-of-life disposal is a concern.
Independent laboratory testing has demonstrated biodegradation under anaerobic conditions according to ASTM D5511. Actual biodegradation rates and results depend on environmental conditions and may differ from laboratory findings.
Bergad's custom formulation capabilities also allow manufacturers to evaluate density, firmness, and other physical properties to meet their product requirements.
Choosing the Right Sustainable Foam
Reducing the environmental impact of viscoelastic foam requires evaluating more than a single material characteristic. Renewable content, biodegradability, durability, and end-of-life management each address different aspects of sustainability.
For manufacturers evaluating alternatives to conventional polyurethane foam, Bergad offers biodegradable material technology alongside custom formulation and manufacturing expertise.
