Circular value chains for sea-based plastic in Norway

Sea-based activities is a major contributor to marine litter in Norway. With an EPR scheme on its way, Norwegian fishing and aquaculture industry is bound to improve collection and waste management of used plastic equipment. This seminar will give an overview over progress and discuss challenges with sea-based marine plastic waste in Norway.

Carl Höjman  is the area manager on marine litter in SALT, a Norwegian private advisory. MSc in sustainable business leadership, with 13 years experience as consultant within environmental services.

Pioneering a circular economy model: how Aquafil is turning waste in into regenerated ECONYL® yarns

Aquafil, a multinational company, that produces a revolutionary alternative to nylon, called ECONYL®, obtained from waste, is known as a pioneer of the circular economy and an innovator of sustainable production models in the synthetic materials industry, with factories in nine countries on three continents. Its Slovenian branch, AquafilSLO, is one of the centres for innovative sustainable technologies. Thanks to a proprietary chemical recycling process it manufactures a 100 % regenerated nylon ECONYL®  from waste, such as fishing nets, carpet waste and industrial waste. The infinitely regenerable ECONYL® nylon offers the same quality but has up to 90 % lower carbon footprint compared to the standard nylon. Econyl® nylon yarns are a sought-after ingredient of many sustainable brands in the fashion, automotive and interior industry.

Tina Mavrič is a marketing and public relations specialist at AquafilSLO.

Pomen trajnostnega lightweight koncepta v avtomobilski industriji

From the perspective of a pre-development supplier in the automotive industry, the lecture will briefly present the challenges of the green transition, which it responds to with a sustainable lightweight concept in the development and production of pre-assembled assemblies with a load-bearing function for the automotive industry. The importance of the sustainable lightweight concept in the development and production of automotive components that leave a minimal carbon footprint in the entire chain from production, use to vehicle recycling will be presented, as well as which research and development activities are necessary for it.

Vili Malnarič is employed at TPV AUTOMOTIVE d.o.o., as head of the development research group of TPV or as Director of Research. He received his master’s degree from the Faculty of Mechanical Engineering, University of Ljubljana. His areas of development and research work are: mechanics, construction, development evaluations, analysis of measurements, statistics and materials.

Additive manufacturing in joint replacement design

Additive manufacturing (AM) has many advantages for producing orthopedic implants, such as joint replacements, that require high customization, complexity, and biocompatibility. AM can create implants with porous structures that promote bone ingrowth and fixation, as well as reduce stress shielding and implant weight. AM can also produce implants with patient-specific geometries and features that match the anatomy and biomechanics of the individual. AM can use various materials, such as metals, ceramics, polymers, and composites, to create implants with different mechanical and biological properties. The aim of this contribution is to provide an overview of advances in the field of additive manufacturing for joint replacement development and design. This contribution will also discuss the challenges and opportunities of AM for orthopedic applications and suggest some directions for future research.
