1. 16. Environmental issues from sugarcane plantations in Brazil and how to handle them with market-based instruments

   University essay from Lunds universitet/Miljövetenskaplig utbildning

   Author : Freja Milton; [2019]
   Keywords : Market-based instruments; environmental offsets; Payments for ecosystem services; PES; Brazil; bioplastic; biopolymer; sugarcane; certification; environmental impacts from sugarcane cultivations.; Earth and Environmental Sciences;

   Abstract : This study is a literature review of three market-based instruments used for land management; environmental offsets, payments for ecosystem services (PES) and certification, and how they could be used to mitigate environmental impacts from sugarcane cultivation in Brazil when purchasing biopolymers. The study showed that certification is the most common market-based instrument in Brazil. READ MORE

3. 17. Thermoset biopolymer reinforced with carbon-nanotubes

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Morteza Esmaeili; [2019]
   Keywords : biopolymers; bio-composites; glycerol lactic acid; carbon nanotube; reinforcement; thermoset; dispersion;

   Abstract : Compared to conventional fibers, carbon nanotubes possess several significant properties, which make them as an excellent alternative reinforcement in multi-functional material industry. In this study, the possibility of dispersion of the multi-wall carbon nanotube (MWCNTs) in a thermoset bio-based resin (synthesized based on end-functionalized glycerol-lactic acid oligomers, GLA, at university of Borås) was investigated.

   Keywords : Biopolymer contamination; HDPE blends; PHA blends; PP; PET blends;

   Abstract : The recycling industry which is efficiently functioning now has technical expertise, contented consumers, and resource availability and capital contributors. The potential inflow of new material into this existing system should be able to fulfill all the needs of the stakeholders involved in it. READ MORE

6. 20. Fluorescence probes: towards automatic coagulant dosing

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Daphné Lecellier; [2018]
   Keywords : Drinking water quality; Water treatment process; Coagulation; Microcystis aerugosa; algal organic matter; LC-OCD; EEM; powdered activated carbon; Alum;

   Abstract : There is a current lack of accurate tools to determine the concentration of cyanobacteria in situ.  Besides, cyanobacterial blooms have to be carefully monitored in reservoirs as they are more frequent because of climate change and can lead to potential released of toxins, along with other components.
