1. 1. Analytical Methods for High Molecular Weight UV Stabilizers

   University essay from KTH/Kemi

   Author : Elin Ljungström; [2022]
   Keywords : hindered amine light stabilizers; light stabilizers; polyolefins; LC-MS; HPLC; hindrade aminljusstabilisatorer; ljusstabilisatorer; polyolefiner; LC-MS; HPLC;

   Abstract : Utomhusprodukter gjorda i plast är sårbara för nedbrytning på grund av UV-energi från solljus. För att stoppa denna fotonedbrytning används UV-stabilisatorer i plastmaterial; en av huvudkategorierna är hindrade aminljusstabilisatorer (HALS, hindered amine light stabilizers). READ MORE

3. 2. Exploring an alternative metabolic pathway for production of adipic acid - a study on homocitrate synthase

   University essay from Lunds universitet/Examensarbeten i molekylärbiologi

   Author : Damaride Stallone; [2019]
   Keywords : Biology and Life Sciences;

   Abstract : Adipic acid is considered as the most valuable dicarboxylic acid with industrial use; however, its production is heavily petroleum-based. This non-natural metabolite can be produced de novo through different metabolic pathways, one of which is the alpha-ketoacid elongation pathway. READ MORE

4. 3. Identification of Environmental Plastic Samples from a Caribbean Beach Survey by Near-Infrared Spectroscopy with the MicroNIR and Chemometric Analysis

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : David Vigren; [2015]
   Keywords : MicroNIR; Near-infrared spectroscopy; Chemometrics; Plastic polymer identification; Environmental plastic beach survey;

   Abstract : MicroNIR is a portable near-infrared diffuse reflection spectroscope. Its suitability for identifying environmental plastic polymers was evaluated through a series of performance tests. The plastic samples were collected during a beach survey in the Caribbean. First a reference database was built by analysing a series of reference plastic polymers. READ MORE

5. 4. Developments in the End-of-Life management of plastics A Western European Overview: moving away from disposal

   University essay from Lunds universitet/Internationella miljöinstitutet

   Author : Brian E.C. McCarthy; [2005]
   Keywords : Plastics waste management; bio-polymers; mechanical recycling; feedstock recycling; chemical recycling; recovery options; policy intervention; Environmental studies; Miljöstudier; Earth and Environmental Sciences;

   Abstract : Plastic materials come in a variety of forms from non-renewable resource based thermosets and thermoplastics to renewable resource based bio-plastics each of which have unique qualities and properties. These materials are seeing ever increasing production and consumption rates throughout Western Europe, being utilized in a growing number of products which inevitably enter the waste stream upon end of life.
