The document summarizes several presentations given at a seminar on forest and plant health held on November 11th, 2022 at the Natural Resources Institute Finland in Helsinki.
The first presentation summarized a 20-year study on the effects of restoration treatments including prescribed burning, dead wood creation, and retention trees on dead wood diversity and epixylic communities in boreal spruce forests. Preliminary findings showed long-term benefits of these treatments for maintaining dead wood and wood-inhabiting diversity.
The second presentation discussed a study on intraspecific growth variation in Norway spruce, finding that soil variation and genetic factors significantly influence functional trait variation, but specific soil agents causing environment-specific growth patterns require more researchOrgaanisten lannoitteiden hiilisyöte ja lannoitusvaikutus nurmen perustamis- ...

This document summarizes a seminar on forest and plant health held on April 6th, 2022 at the Natural Resources Institute Finland in Helsinki. It includes summaries of several presentations:
1. Tord Snäll presented research on evaluating forest management scenarios and their impacts on biodiversity indicators and ecosystem services over 100 years. The green infrastructure scenario optimized environmental indicators while the economy scenario had the most negative impacts.
2. Juha Tuomola discussed research assessing the likelihood of pine wood nematode causing pine wilt disease or establishing in Finnish forests under current and future climate scenarios. Results found the climate is currently too cool and may only become suitable by 2080 under the worst-case climate scenario.

This document summarizes a study analyzing 123 texts written by Finnish high school students aged 15-18 describing their visions of sustainable food systems in Finland in 2050. Through qualitative analysis, the students' visions were condensed into 6 alternative futures: 1) Slow change 2) Domestic and local production 3) Conscious consumer 4) Regulation 5) Technology 6) Dystopia. The visions highlighted big changes to diets and food sources, concerns about plastic packaging, and ensuring social and economic sustainability through eating together and valuing producers. The students proposed technological solutions and ideas to reduce packaging waste through better recycling, less packaging, new materials, and reuse.Chasing the moving target: the role of emotions in strategic packaging decisions

The document summarizes research on how emotions play a role in strategic packaging decisions for sustainability. It discusses how packaging development requires balancing usability, saleability, environmental friendliness and production effectiveness. Managers face dilemmas in balancing these factors as sustainability targets change. The research examines how emotions like satisfaction, frustration, and worry influence how managers evaluate opportunities and make decisions. It proposes that understanding emotions can help managers commit to responsible packaging solutions and navigate uncertainties when sustainability goals are evolving.To pack or not to pack green: ympäristövastuullisen päätöksenteon haasteita

This document discusses sustainability decisions for businesses. It notes that sustainability can provide competitive advantages like efficiency, reputation benefits, and avoiding future regulations. However, sustainability orientation does not always lead to improved firm performance and may require large trade-offs. Studies discussed found that willingness to switch to more sustainable materials depends on factors like a product or process's dependency on existing materials and environmental friendliness as a predictor of change. The document advocates making sustainability decisions by responding to and anticipating stakeholder needs and feelings, including others' perspectives, and considering one's responsibilities.Moving from cross-system interaction to cross-system collaboration?

This document discusses sustainability transitions in food packaging from the perspective of companies. It defines sustainability transitions as long-term transformations to more sustainable production and consumption. For food packaging, this involves innovations that meet changing societal values around policy, media, consumer and supply chain demands. However, barriers like complexity, uncertainty and competition exist. Collaboration is seen as key to overcoming barriers by creating shared understanding and multi-party problem solving. Currently, companies collaborate through associations, but different roles in relation to change exist, from maintaining the status quo to facilitating change. Ongoing and upcoming facilitated dialogues and the PackageHeroes transition arena aim to further cross-system collaboration for deciding concrete transition pathways.Visiot kestävästä ruokapakkaamisesta 2050

The document presents visions for sustainable food packaging in Finland by 2050. It describes workshops and interviews conducted with stakeholders to develop these visions. The visions are categorized based on their depth of change and breadth of involvement across different systems and actors. Example visions include a future with intelligent delivery systems and limited reusable packaging, as well as standardized packaging that improves recyclability. The document concludes that continued cooperation across food packaging systems and levels of government and industry is needed to realize these visions and transform the packaging system for sustainability by 2050.Package design and the consumer panel

This document discusses consumer cultures and food packaging from an ethnographic research perspective. It defines consumer culture and argues that qualitative research is needed to understand how identities are shaped by consumption and how consumption habits are molded by identities. The roles of food packaging in consumer choices and everyday lives are examined. The document also outlines the history of food packaging from industrialization to today's single-use plastic culture and takeaway trends. It reflects on stakeholders' differing views of responsibility in transitioning to sustainable packaging and consumers' challenges with sorting and recycling.Biopohjaiset pakkausmateriaalit: markkinat, raaka-aineet ja kestävyys

This document discusses several topics related to fibre-based packaging materials, forests, and sustainability:
1) The global market for paperboard packaging is expected to grow steadily reaching over $200 billion by 2026, driven by changing consumer preferences for more sustainable options. Growth is highest for stand-up pouches and liquid cartons.
2) As pulp use in paper decreases, surplus pulp could be allocated to increasing production of paperboards, food and beverage packaging, or new pulp-based products. However, price and EU policies will influence these allocation decisions.
3) Finnish forests can sustain current wood harvest levels through 2035 but increased harvesting risks failing to meet biodiversity and climate targets unless additional conservation measuresEnvironmental benefits of re-usable food packaging

The document analyzes the environmental benefits of reusable food packaging compared to single-use plastic packaging. It finds that reusable packaging decreases CO2 emissions. Specifically, a reusable box reused 100 times reduces CO2 emissions by 76% compared to a single-use box if recycled at end of life, and reduces emissions by 94.69% compared to a single-use box if incinerated at end of life. Recycling provides better environmental benefits than incineration as an end of life option. However, 100% recycling is not possible in practice. The energy sources and customer reuse behavior also influence the final results.Pakkaussuunnittelun rooli elintarvikepakkauksiin liittyvien ympäristövaikutus...

The document summarizes a study that investigated the environmental impacts of novel packaging materials compared to conventional plastic packaging. The study looked at reducing impacts through package design changes like using less material, replacing plastics with fibers, and developing new materials. It analyzed demo cases of different packaging alternatives and their life cycles. The results found that a recyclable plastic and a new material based on modified PLA had lower carbon footprints than conventional plastic or current fiber-based packaging. The end-of-life scenario significantly impacted the results, with fiber-based packaging having a lower footprint than plastics under incineration but not recycling.Elinkaariarviointi (LCA) pakkausratkaisujen ympäristökestävyyden määrittämisessä

The document discusses using life cycle assessment (LCA) to evaluate the environmental sustainability of packaging solutions and meet upcoming EU targets. It notes that recycling targets alone will not be enough to achieve the EU's climate neutrality goal by 2050. An example LCA compares the global warming potential of different salad wrapper materials and recycling rates. While LCA is useful, the document concludes that further development is still needed to fully account for factors like agriculture, forestry, land use, energy production, carbon stocks, and indirect impacts.Packaging material development – from lab to pilot

This document summarizes the development of new bio-based packaging materials from the lab scale to pilot production. Researchers produced multilayer structures using materials like bio-PBSA, PLA-X, fibrillated cellulose, and paper through extrusion coating and dispersion coating. Barrier properties were characterized, and pilot lines were used to produce demo packages for testing. While scaling up presented challenges that impacted material performance, the results demonstrate the viability of producing these novel bio-based packaging solutions at a larger scale. Further optimization is still needed to improve barrier properties and reduce costs.Muovin korvaamispotentiaali elintarvikepakkauksissa. Case: Suomalaiset superm...

The document analyzes the use of plastics in food packaging in Finnish supermarkets to identify areas for potential substitution or reduction. Key findings include:
- Plastic is widely used across food categories, especially for meats, sausages, and fresh produce. Legislation restricting single-use plastics provides an impetus for substitution.
- Candies, ready meals, and energy drinks were identified as categories with high plastic use and sales volumes, presenting opportunities to reduce plastic packaging.
- No single solution exists - more sustainable packaging will combine reduced material use, reuse systems, improved recyclability, and alternative materials to plastic. Careful analysis is needed when substituting packaging materials.More Related Content

Typpi-inhibiittori naudanlietteessä - koetuloksia kuivissa kasvuoloissa
- 1. • Nurmen 2. sato VL:lla 700-800 kg ka/ha parempi kuin V+LL ja LL. Lietteiden välillä ei eroja. • V. 2021 nurmen 1. sato V+LL 5,8 tn sekä LL ja VL 5,5 tn ka/ha, mutta ero ei ollut merkitsevä. • Nurmen 2. sadon D-arvo oli lietteillä korkeampi kuin VL:lla • Peltokokeessa V+LL kasvusto oli toisella tilalla korkeinta, mutta ei toisella (15 mittausta/lohko). • Kuivuusjaksot saattoivat vaikuttaa tuloksiin ja typpi- inhibiittoria tulisi testata myös sateisissa oloissa. Tausta: Vizura -typpi-inhibiittorin tavoite on hidastaa naudan lietelannan typen huuhtoutumista. Tuotetta testattiin OrVo- hankkeessa Luke Maaningalla ja peltokokeissa maatiloilla. Koe: Lohkoittain satunnaistetut ruutukokeet (n=4) 2020–2021 a) Ohra; Vizura+liete (V+LL) ja liete (LL) 90 kg Nliuk/ha b) Nurmi; V+LL ja LL, kontrollina väkilannoite (VL). Typpitaso 100+100+0 kg Nliuk/ha, josta lietteenä 2. sadolle v. 2020 45 ja v. 2021 72 kg Nliuk sekä syksyllä 2021 25 kg Nliuk/ha. Lisäksi peltokoe (n=1) kahdella tilalla nurmen 2. sadolle v. 2021; V+LL, LL ja lannoittamaton. Tulokset: • Ohran keskisato 2020 ja 2021 oli 4 tn ja 2,8 tn/ha. Tsp V+LL (40 g) hieman korkeampi kuin LL (39 g) Arja Mustonen¹, Henna Hyttinen², Maarit Termonen¹, Hanna Mäkinen³ ja Kirsi Järvenranta¹ ¹Luonnonvarakeskus, ²Savonia-ammattikorkeakoulu, ³BASF Oy Typpi-inhibiittori naudanlietteessä – koetuloksia kuivissa kasvuoloissa Maataloustieteen Päivät 14.-15.6.2022, Helsinki etunimi.sukunimi@luke.fi 0.0 1.0 2.0 3.0 4.0 5.0 V+LL LL V+LL LL tn/ha Ohrasato (15 % kosteus) 2021 2020
