With rising environmental awareness, companies are searching out sustainable packaging to show both social responsibility and satisfy conscientious consumers. The recent emphasis on eco-friendly materials, production methods, and disposability dramatically transforms packaging across industries. Even small shifts toward greener solutions make substantial supply chain impacts.
Adopting Plant-Based Plastics
Most packaging plastics derive from fossil fuel feedstocks like natural gas and crude oil. Manufacturing common wraps and fillers such as polyethylene, polystyrene, and polypropylene leaves a significant carbon footprint. Bioplastics using renewable plant starches, sugars and oils present an eco-alternative.
Corn, sugarcane, and hemp convert into packaging-grade polymers matching conventional plastic properties without petrochemical resource depletion. Some innovators, like Epsilyte, even develop biodegradable EPS from natural latex and plant oils. As bioplastic costs decrease and production scales, widespread substitution of traditional plastics becomes feasible.
Optimizing Manufacturing Efficiency
Energy-intensive manufacturing worsens packaging sustainability profiles. Reducing electricity demand, cutting waste percentage, and improving material yields shrink the lifecycle impacts of packaging operations.
Adjusting extruder temperatures and optimizing blow film thickness balances quality and efficiency. Recirculating usable plastic scraps back into production as regrind minimizes discard volumes. Investing in the latest container molding and filling equipment boosts output per energy input. Overall, enhanced process oversight and upgraded machines achieve sizable sustainability gains.
Designing for Supply Chain Efficiency
Excess packaging size and weight burden distribution chains reliant on fossil fuels for transport. Eliminating unnecessary mass directly lowers emissions from trucks, planes, and ships. Downsizing to right-fit dimensions also packs more products per cargo load.
Some manufacturers even design interlocking packaging for denser stacking configurations inside containers. Eliminating wasted space cuts required shipments along the supply chain. These logistics-based efficiency tactics make substantial cumulative impacts without changing materials.
Prioritizing Recycled Content
Supplementing a portion of virgin materials with recycled plastics or papers further lessens environmental burdens associated with packaging production. Post-consumer recycled PET from discarded bottles often constitutes 30% of new plastic packaging. Cardboard boxes increasingly feature 25-100% recycled pulp.
Brands advertise higher recycled content percentages to attract sustainability-minded consumers. Some companies close the material loop by recycling internal plastic waste into future packaging.
Pursuing Renewable Energy
Around the world, packages are manufactured by electric power grids dependent on fossil fuels like coal and natural gas. Transitioning factories to run on renewable energy sources like solar, wind or hydropower alleviates emissions tied to packaging creation.
Consumer brands with far-reaching influence incentivize contract packagers to prioritize renewables via power purchase agreements that fund additional green power capacity. Company investments ultimately grow the wider grid supply for all users.
Simplifying Materials for Recyclability
Mixing material types and using composite constructions hamper packaging recyclability despite marking codes. Keeping things simple improves recovery outcomes after use.
Monolayer films without secondary glues and barriers give recyclers higher value product to reprocess. Separable paper labels, caps, and removable adhesive enhance plastic and cardboard breakdown. Purposefully engineering recyclable packaging better perpetuates resources.
Embracing Compostable Materials
Compostable bioplastics break down into organic matter to enrich soils rather than overload landfills. Innovators develop compostable foams, films, and protective sheets as fossil plastic replacements. Durable containers made of bamboo, bark, and bulrush fibers biodegrade after use as well.
Finished food and yard waste compost even contains fragmented packaging remnants as high-quality soil amendments. Closing the loop with composting and anaerobic digestion diverges waste while regenerating nutrients for plant growth.
Conclusion
Greener packaging solutions benefit the environment across material choices, manufacturing practices, and end-of-life options. As eco-conscious companies implement bioplastics, production efficiencies, recycled content, renewable energy, recyclability, and compostability, substantial waste savings accumulate. Major brands shifting toward sustainability compel global supply chain-wide change.
