What lifecycle assessment (LCA) metrics differentiate resin, WPC, and traditional outdoor sofa materials?

Lifecycle assessment (LCA) is a critical tool for evaluating the environmental impact of materials used in outdoor furniture, such as resin, wood-plastic composite (WPC), and traditional options like wood or metal. Key LCA metrics that differentiate these materials include carbon footprint, energy consumption, recyclability, durability, and toxicity.

Resin, often made from polyethylene or polypropylene, has a high carbon footprint due to fossil fuel extraction and processing but offers excellent durability and low maintenance. WPC, a blend of wood fibers and plastic, strikes a balance with moderate energy use and better recyclability than pure resin, though its longevity depends on quality. Traditional materials like teak or wrought iron may have lower embodied energy if sourced sustainably but often require more maintenance and have higher end-of-life waste.

By analyzing these LCA metrics, consumers can make informed choices based on sustainability priorities—whether favoring recyclability (WPC), low upkeep (resin), or natural aesthetics (traditional materials).
