21. Produktion av polyhydroxyalkanoater (PHA) av avloppsvatten från massa och pappersindustri : En studie kring bakteriernas förmåga att ackumulera PHA beroende på sammansättning av karboxylsyror
Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Since the beginning of the 20th century plastic has been a widely used material, which has resulted in large quantities of plastic being produced in the last century. The plastics of today are mainly produced from fossil raw materials, which gives it a high climate impact. LÄS MER
22. The biodegradable straw - Investigating how enzymes can be used to enhance desired product qualities of drinking devices.
Master-uppsats, Lunds universitet/InnovationSammanfattning : The increasing production of single-use plastics negatively affects the climate. The resulting plastic ocean debris has fatal consequences to marine life. As a result, the European Parliament has placed a ban on single-use plastics by 2021, making it essential to study sustainable materials for single-use products such as straws. LÄS MER

24. Smart Plug – Optimization of design and material regarding environmental aspects : Mechanical design of an environmentally friendly Smart Plug
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : A Smart Plug is a remote-controlled power socket that allows the user to, through an app, control any appliances that is plugged into the outlet. Since not all appliances are constructed with a smart function, the usage of a Smart Plug can be beneficial to facilitate the everyday life. LÄS MER
25. Tillverkning av polymerer från skogsindustriellt bioslam : Temperaturens inverkan på PHA-ackumulering i skogsindustriellt bioslam från Gruvöns bruk i Värmland, Sverige.
M1-uppsats, Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik; Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Plast i naturliga miljöer är ett stort problem i dagens läge då materialet oftast inte är 100 %biologiskt nedbrytbart. Plasten bryts ner till bitar i mikrostorlek, dvs. under 5 mm. Mikroplasten ackumuleras i landmassor likväl som i vattendrag och hav. LÄS MER
