Cellulose for Sustainable Packaging

Method for manufacturing a rigid, eco-friendly paper string for packaging that can replace plastic straps. The paper string is made by applying an adhesive to a paper base, joining two side bands, folding the paper multiple times, coating it, and winding it. This provides a paper string that is stronger, doesn't break easily, and can be reused or recycled after packaging. The coated paper string is wound around a roller to increase rigidity. It is a sustainable alternative to plastic straps as it can be reused, recycled, and composted after use.

Eco-friendly cushioning packaging material made from natural pulp like sugarcane and bamboo instead of plastic or wood pulp. The packaging material is manufactured by processing paper made from the natural pulp. To reduce dust generation from the short fibers of sugarcane pulp, a small amount of bamboo pulp is added during fabric production. The paper surface is coated with starch and biodegradable wax to improve strength and water resistance. This allows replacing traditional plastic cushioning materials with a more sustainable option that reduces plastic usage, carbon emissions, and environmental pollution.

A process for manufacturing biodegradable and compostable packaging material from flower waste. The process involves extracting cellulosic substance from dried flower waste using sodium hydroxide, then combining it with a water-soluble polymer, adhesive, epoxy resin, and hardening agent to form a viscous solution. The solution is stirred, pressed, and cured to create the biodegradable packaging material. The flower waste-based packaging is compostable and degrades easily when buried.

Preparing a grass-derived multifunctional nanomaterial film for food packaging that enhances mechanical properties, water resistance, UV protection, oxygen scavenging, and antimicrobial properties. The film is made by incorporating nanomaterials extracted from dried darbha grass, like carbon dots, cellulose nanofibers, and silver nanoparticles, into PVA films. The grass nanomaterials improve the film's performance compared to standard PVA films.

Process to make biodegradable bottles using natural materials like areca leaf and cellulose bio-polymer. The process involves cleaning and soaking the areca leaf sheath, drying it, compressing it with cellulose film to form a biodegradable material, thermoforming into bottle shape, and trimming. The resulting biodegradable bottle reduces plastic waste and promotes environmental sustainability compared to conventional plastic bottles.
