Resumen de: WO2026055774A1

Disclosed are biochar-infused composite materials designed for applications in construction, packaging, and/or horticulture. The materials, integrating biochar into matrices of starch, paper, cardboard, molded pulp, peat moss, cellulose, chitosan, polylactic acid (PLA), gelatin, PLA (Polylactic Acid), pectin, agar, or other natural polymers, taken alone or in combinations, enhance key mechanical properties like rigidity, moisture resistance, and impact protection. These composites offer environmental benefits, such as carbon sequestration and pollutant absorption, contributing to long-term sustainability. Customizable biochar concentrations and particle sizes allow for application-specific optimization, making the materials versatile across industries. Packaging solutions not only protect products but also act as vehicles for distributing biochar globally, at no extra cost. Once the packaging has served its purpose, it can be composted to improve soil health and sequester carbon, thus supporting climate action goals. The use of starch further enhances biodegradability, aligning with the vision of promoting a circular economy.
