1. Selected PFAS in the water treatment at the waste-to-energy plant in Umeå : Investigating concentration and composition of selected PFAS in different water treatment steps
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : The present study investigated the changes in concentration and composition of five selected PFAS substances in the water treatment at the waste-to-energy plant in Umeå. The five PFAS were PFHxA, PFHpA, PFOA, PFHxS and PFOS. As PFAS exists in a variety of consumer products, they will to some extent end up in waste incineration. LÄS MER
2. Qualitative Analysis of Chlorinated Paraffins in Recycled Plastics
Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Described in many studies as dangerous for the environment and potentially carcinogenic for humans, Chlorinated Paraffins (CPs) are easily widespread due to their substantial production and use in different products. Previous studies reported the presence of CPs in different plastic polymers. LÄS MER
3. Återbruk kontra återvinning av litiumjonbatterier
Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : I Sverige läggs stort fokus på omställningen till ett hållbart och klimatneutralt samhälle, där avkarbonisering och elektrifiering av transportsektorn anses avgörande för att minska utsläpp av växthusgaser. En storskalig batteriproduktion i Sverige och i Europa medför nya problem kring hållbarhetsaspekter gällande utvinning av råvara som exempelvis litium, kobolt och nickel. LÄS MER
4. Analysis of fatty acids in fatty acid-based herbicides by gas chromatography
Master-uppsats, Lunds universitet/Kemiska institutionenSammanfattning : Fatty acids-based herbicides are considered to be a green alternative to synthesized weed control products. However, the environmentally sustainable effect of those herbicides needs more investigation to be confirmed. LÄS MER
5. Towards Water Resource Recovery Facilities : Environmentally Extended Techno-Economic Assessment of Emerging Sewage Sludge Management Technologies in Sweden
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Municipal sewage sludge (MSS) management varies widely between countries and legislative regimes. Within the European directive for sewage treatment France applies over half of MSS to arable land, while The Netherlands has banned the practice (Kelessidis et al, 2012). LÄS MER
