1. 21. Full Material Declaration - A case study on the readiness for declaring Full Material Declaration of chemical substances in components, used in finished products

   University essay from Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

   Author : William Lövdahl; [2022]
   Keywords : full material disclosure; full material declaration; FMD; chemical substances in products; CiP; information flow in supply chain; chemical declaration; information flow; chemical; mapping chemical substances; tracking chemical substances; transparency in the supply chain; supplier data sharing; readiness and chemical management; chemical management; chemical disclosure; Earth and Environmental Sciences;

   Abstract : The production and use of chemicals has grown exponentially over the past 50 years. Although the knowledge of hazards and risks associated with chemicals towards humans and the environment has increased, we know frightenedly little about how dangerous these might become when part of finished products.

3. 22. Measuring Acoustic Mobility of Particles by Particle Tracking Velocimetry

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Alexander Edthofer; [2022]
   Keywords : acoustophoresis; microfluidics; polystyrene; cells; particle tracking velocimetry; Technology and Engineering;

   Abstract : Acoustophoresis is a method to manipulate and move cells or particles suspended in a medium using acoustic waves. The speed of the acoustophoretic motion depends on the cells' acoustic mobility, i.e. their size, density and compressibility relative to the medium. READ MORE

4. 23. Low-carbon hydrogen production from waste plastics via pyrolysis and in-line catalytic cracking process

   University essay from KTH/Kraft- och värmeteknologi

   Author : Yanghao Jin; [2022]
   Keywords : Pyrolysis; catalytic cracking; plastics recycling; biochar catalyst; hydrogen production; Pyrolys; katalytisk krackning; återvinning av plast; biokol; produktion av väte;

   Abstract : This study develops a novel pyrolysis process combined with in-line catalytic reforming toproduce high purity hydrogen and carbon products from waste plastics. The input resource is waste plastic material in the form of discarded Covid masks. READ MORE

5. 24. Mapping of Material & Conversion Parameters of Packaging Production – Boardio®

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Yusuf Qasem; Younes Chraibi Ottosson; [2022]
   Keywords : Chemical Engineering; Packaging; Packaging Production; Paperboard; Converting; Lamination; Extrusion; Die-cutting; X-ray tomography; GPI; Creasing; Perforation; Tensile Strength; Technology and Engineering;

   Abstract : With an increased demand for sustainable packaging solutions for the ever-growing FMCG market, fiber-based systems rise as an answer to phasing out plastics in packages and reducing the humanity’s climate footprint. However, constructing a packaging solution largely consisting of paperboard comes with its challenges, such as integrating functionalities in the anisotropic paperboard that formerly were provided by a fundamentally different materials with divergent mechanical properties, being isotropic polymers.

6. 25. Why is plastic waste at recycling centres poorly sorted? A study of the plastic waste sorting at Sysav’s recycling centres

   University essay from Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

   Author : Maja Mosslind; [2022]
   Keywords : recycling centre; plastic sorting; sorting rate; sorting behaviour; sorting quality; plastic waste; waste sorting; Scania; Sweden; Earth and Environmental Sciences;

   Abstract : Reducing plastic waste incineration is crucial for Sweden’s transition to a carbon neutral society in 2045. To achieve this goal, it is essential to increase the material recycling of plastics. READ MORE
