Literature review of reuse systems for bottles
The goal of this project is to review literature on LCAs of reuse systems for bottles as well as the current European practice in reuse systems. In this way, the project aims to provide a broad overview of existing research, reports and general studies of bottle reuse systems in Europe and elsewhere. It also aims to deliver valuable information related to such reuse systems, for example empiric data on trip-numbers. Importantly, the results from the overview of LCA studies as well as current European practice can inform future LCAs of reuse systems. For example, such future LCAs could compare the current deposit system for PET bottles and aluminium cans with potential reuse systems for both PET bottles and glass bottles in Norway, and further compare these to the residual waste system where PET bottles and aluminium cans are collected to be incinerated.
In a presentation on the 4th of May at the SETAC-conference Cecilia Askham, NORSUS, presented findings from the collaboration between PacKnoPlast and MarILCA.
The presentation “How Can Risk Assessment Data for Micro- and NanoPlastics Contaminations Be Generated in a Way That Is Useful for the Development of LCIA Models?” is based on findings from PacKnoPlast and the collaboration with MariLCA.
Cecilia Askham presented the work during the conference session «3.08 – Harmonized Data reporting and analyses in micro- and nanoplastics research».

NORSUS researcher Erik Svanes, together with researchers at NOFIMA, Oslo Met and SIFO, has just published the article , som handler om forbrukernes handlingsmønstre og holdninger ift økt inntak av plantebasert protein. Ut fra deres middagsvaner, verdier og holdninger deles forbrukerne opp i 7 grupper, karakterisert som «flexitarianere», «åpen for vegetarisk mat», «kjøttspisere», «tradisjonalister», osv. Disse beskrives ytterligere ved forhåndsdefinerte “standardpersoner” (“personas”). Ved bruk av resultater fra livsløpsvurderinger (LCA) ser vi at miljøpåvirkningen fra middagen varierer mye fra gruppe til gruppe, noe som hovedsakelig skyldes inntak av proteinmaten, og særlig kjøtt. Gruppene ble plassert i en «innovation adoption curve» som beskriver i hvilken grad de tar til seg innovasjoner. Med noen små, men interessante unntak viser studien at miljøpåvirkningen øker fra innovatørene (som «flexitarianerne») til de i minst grad spiser planteprotein («kjøttspiserne»).
This research can be used to understand consumer actions and how to designed targeted interventions to change eating habits.
NORSUS trenger flere forskere med kompetanse på LCA for vårt viktige arbeid med å skape kunnskapsgrunnlag for bærekraft. Vår nye medarbeider vil være i et kollektivt orientert fagmiljø av 27 engasjerte, flinke og hyggelige forskere på alle nivåer, med prosjekter som spenner fra kortere oppdragsforskningsprosjekter for industrien, til forskningsrådsfinansierte anvendte prosjekter og til flerårige EU-prosjekter. Hovedkontoret er i Fredrikstad, med et prosjektkontor i Oslo. Ta gjerne kontakt for en prat!

En nudge er et lite «dytt» i riktig retning. Det innebærer at mennesker påvirkes til å ta valg uten at man tenker på det. Tradisjonelt støter man på nudging i matbutikkene og på avfallssorteringen. I podkasten får du høre mer om nudging, kommunikasjon og forskningsbehov. Seniorrådgiver Mona Nilsen har vært på besøk i podcasten Sirkulér. I dialog med Nancy Strand reflekterer de sammen om nudging, atferdsendring og forskningsbehov.
Kva er mest klima- og miljøvennleg av vasskraft, vindkraft og solkraft? Og bør ein bruke fleire indikatorar enn klima når ein samanliknar? Forskningssjef Hanne Lerche Raadal og seniorforskar Ingunn Saur Modahl har vore på besøk i podkasten Fornybaren.
April 27. april 2021 Kari-Anne Lyng was elected chairman of the board at the digital annual meeting of Avfallsforsk. Avfallsforsk is a network of actors in the waste- and recycling industry and research organisations working for the stimulation of R&D activities related to waste resources and circular economy.
Kari-Anne Lyng is the coordinator of the research area Waste Resources at NORSUS and has several years of experience with research projects regarding Life Cycle Assessment (LCA) of waste systems. Her doctorate dealt with environmental optimization of biogas value chains with a focus on both drivers, barriers and policy development. She has been project manager for a number of waste-related projects, and now manages the three-year research project Innovative Waste LogisticsKari-Anne is also Norway's representative in IEA task 37 Energy from biogas.
«An important task in the future will be the investigation of utilising different resource as resource efficient as possible, and this also applies for waste resources. Working interdisciplinary across sectors will be more and more important, and I’m sure Avfallsforsk will play an important role here", says Kari-Anne Lyng
Vi gratulerer Kari-Anne Lyng som nyvalgt styrelederverv og sikker på at hennes kompetanse vil bli viktig i Avfallforsks arbeid fremover.
On the 20th and 21st of April Chalmers hosts the Circular Materials conference. NORSUS is represented at the conference on both days. Cecilia Askham will present her work on the 20th (SirkulærPlast) and John Baxter on the 21st (capturing the real environmental benefits of product reuse).
The SirkulærPlast project: realising circular innovation in Norway
The SirkulærPlastproject (2017-2020) has worked towards innovation in circular plastic materials based on three real-life cases covering three different thermoplastic materials: high density polyethylene (HDPE), Polypropylene (PP) and glass-reinforced nylon (PA6.6). The project was financed by project partners and the Oslofjordfond Regional Research fund, Norway. The companies involved have a healthy collaboration network, despite sometimes being competitors in a fiercely cost-driven market. The SirkulærPlast project consortium included actors from the whole circular life-cycle required for products. Central activities in the project were quality testing and environmental accounting (LCA) work to inform innovation. The participants have learnt a lot about the benefits, challenges and some solutions for using recycled materials in practice. Sharing the knowledge built up during this research project is important and the platform for this will be presented.
Capturing the real environmental benefits of product reuse
End-of-life interventions such as material recycling and product reuse are widely recognised as delivering important environmental benefits. However, these benefits may not be as readily identified as it might seem. For instance, it has been noted that reuse merely delays the final disposal of a product and does not deliver reduced impacts over its total life cycle. The key is focusing on the appropriate spatial and temporal system boundaries, relating to the provision of product function. Comparisons between reuse and make-use-dispose pathways must focus on the function provided and fairly account for this in each case The study explores these issues for a range of consumer products including electronics.It emerges that product reuse requires more complex and multi-faceted analysis than is often recognised.
To meet ambitious recycling targets for plastic packaging, there is an urgent need to solve scientific and technilogical challenges to meet both the legislative food safety requirements and the plastic packaging recycling requirements, while enabling the use of recycled plastics in food packaging. The project investigates the promising options of closed loop polyolefin recycling and the use of recycled plastics in food packaging with a functional barrier. NORSUS will carry out an environmental assessment of the case products and recycling systems. In addition, LCA will be used to quantify the projects’ contribution towareds the sustainable development goals.
