Table 2 Key recommendations to improve the sustainability of polyester garments during the production phase of the value chain. GHG = greenhouse gas
| Issue | Goal | Measure | Action |
|---|---|---|---|
| Inputs | Phase out fossil fuels as source of energy | Strict taxes on GHG emissions |
|
| Discontinue buying/selling quotas on GHG emissions |
| ||
| Discontinue subsidies for use of fossil fuels |
| ||
| Incentivize use of renewable energy |
| ||
| Phase out fossil fuels as source of materials | Prioritize recycled PET pellets for production of new polyester fibers |
| |
|
Further investigate the environmental impacts, safety and economic feasibility of: Renewable monomers ethylene glycol and TPA for the production of PET pellets Renewable polyesters such as polylactic acid Renewable dyes and other chemicals |
| ||
| Optimize and upscale the use of renewable feedstock |
| ||
| Consider materials other than polyesters that may be more sustainable |
| ||
| Reduce water consumption | Prioritize dyeing/printing methods that require less water |
| |
| Encourage water recycling |
| ||
| Outputs | Reduce water pollution | Impose wastewater treatment |
|
| Reduce microfiber release | Prioritize compact yarn structures (high twist, longer filaments) |
| |
| Prioritize thermal cutting methods |
| ||
| Reduce waste | Improve management of chemical residues |
| |
| Smart design through digital tools to reduce cut-out pieces |
| ||
| Recycle cut-outs back into the supply chain |
| ||
| Design | Design for durability and recyclability | Work with high-quality materials for durable clothing |
|
| Discontinue use of hazardous chemicals and dyes to increase recyclability |
| ||
| Avoid blends when possible to increase recyclability |
| ||
| Transport | Supply chain optimization | Shorten the supply chain |
|
| Implement traceability through digitalization |
| ||
| Reduce oil, chemical and polymer pellet spills |
| ||
| Retail | Make the purchase of sustainable clothes easier | Implement strict eco-labeling |
|
| Include reuse and recycled garments in regular stores |
| ||
| Place retail stores at accessible locations |
| ||
| New business models | System based on pre-orders |
| |
| Fashion as a service (subscription or pay-per-use) |
