This study evaluates the environmental performance of three novel feather treatment processes ((Steam Explosion (SE), Microbial Fermentation (MF) and Mechanical Grinding (MG)) intended for producing sustainable bioplastic feedstock, using Life Cycle Assessment. A gate-to-gate analysis compared the processes per 1000 kg feather input across multiple impact categories, including GWP, Acidification Potential (AP), Eutrophication Potential (EP), Respiratory Inorganics, and Water Scarcity. The scope was expanded to cradle-to-gate to include upstream farming impacts and compare results with conventional plastics. Gate-to-gate results showed MG had the lowest impacts for GWP (475 kg CO<sub>2</sub> eq.), AP (0.65 kg SO<sub>2</sub> eq.), EP (0.08 kg Phosphate eq.), and Respiratory Inorganics, driven by lower energy use. However, MG showed the highest Water Scarcity (7787 m3 world eq.) due to feather washing. MF exhibited the highest GWP (2035 kg CO<sub>2</sub> eq.) and Respiratory Inorganics, while SE showed the highest AP (1.25 kg SO<sub>2</sub> eq.). Cradle-to-gate, MG and SE offered significant GWP advantages over conventional plastics like PP, LDPE, and HDPE (up to 59 % and 27 % lower GWP, respectively). Similarly, MG and SE demonstrated lower AP (up to 56 % and 48 % lower, respectively) compared to these plastics. However, feather routes showed higher EP when upstream farming impacts were included. In conclusion, MG is the most favourable process regarding climate impact, though its water use is significant. SE provides a balanced alternative. Valorising feather waste offers environmental benefits over conventional plastics, but optimising energy efficiency and water consumption is crucial for enhancing the sustainability of these technologies.</div></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"19 ","pages":"Article 100372"},"PeriodicalIF":4.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145690355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A criterion LCA-based framework aligned with the ISO 14044 hierarchy and tailored specifically to desalination has been developed. It guides the selection of allocation approaches based on system characteristics, integration level, and assessment objectives and is applied to assess an MLD system which co-produces desalinated water, sodium chloride, magnesium hydroxide, calcium hydroxide, sodium sulphate and hydrochloric acid. Multifunctionality was handled with system expansion and partitioning (physical and economic) approaches, resulting in different functional units. For physical and economic partitioning, the MLD system is modelled from a process and system perspective. The results indicate that the MLD system has larger environmental benefits than the reference system with system expansion. When physical and economic partitioning under different perspectives are applied, they result in different environmental burdens per co-product. The MLD system performs better than the reference system (0.005 kg CO<sub>2</sub>/kg desalinated water) only when process economic partitioning (0.003 kg CO<sub>2</sub>/kg desalinated water) is applied.
