Early phase design tool for non-LCA experts : Integrating environmental assessment in the development of novel processing technology in food industry
- 2017
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The Life Cycle Assessment methodology often applies a product perspective but can be used to assess novel production technologies by comparing novel products with a baseline product, as long as the functional unit of the product is considered to be the same. There is increasing environmental concerns in society and pressures on industry to take into account their impact on the environment. Tools are available for this, but not tools adapted to specific industry needs. The reasons to use LCA are foremost to guide the development towards the most sustainable solutions and to evaluate the market potential from an environmental perspective. Challenges arise when applying LCA in early development stages, e.g. getting access to recent development data, to increase commitment and incentives to take early LCA results into consideration, to present results in an attractive way etc. LCA calculations must also keep up with the sometimes rapid development. In order to meet these challenges interactive report software have been introduced to industrial partners (non-LCA experts) in an EU project called FutureFood (Grant agreement no: 635759). The project goal is to develop a new processing technology for foods (CO2 drying). In order to meet the LCA related challenges a platform has been used that is developed by PRé Consultants (Pre, 2016?), called Share and Collect. It allows LCA experts to develop tools for non-experts so that users are able to alter parameters in the LCA model and assess the result of the changes. It is done by providing the industrial partners with an intuitive web based graphical user interface (GUI). When a user changes input data in the GUI, parameter values also change in the model, an LCA calculation engine runs the model and the GUI presents the corresponding results. In the project a tool for assessing the processing technology has been developed and the industrial partners are provided rights to access the tools and create ‘what if’ scenarios. Examples of changes are change of electricity production, transport distances, transport types or modes, raw material source, packaging, production resource or energy efficiency etc. The tool has been evaluated by the non-LCA expert industrial partners, and the first review results show that it is user friendly, visually appealing and interesting in its interactive way because of the instant feedback of results. Tailored models such as the ones developed in the project have the potential to support knowledge based decisions in innovation projects in companies.

Mer specifikt syftar projektet till att hjälpa till med att ta fram målsättningar och att nå målen med ett holistiskt angreppsätt, där samtliga frågeställningar beaktas och där uppfyllandet av ett eller några mål inte sker på bekostnad av andra målsättningar.De frågeställningar eller områden som har inkluderats i det här projektet är klimatavtryck från livsmedelsinköp, andel ekologiska livsmedel av totala inköp, andel svenska livsmedel av de totala inköpen och matsvinn.Dessa områden beskrivs i rapporten och det ges nationella riktlinjer för vart och ett av områdena. Även nuläget för respektive område presenteras, d.v.s. var de som använder Hantera befinner sig just nu. Eventuella målavvägningar mellan områden, d.v.s. om det föreligger konflikter gås igenom. Det ges också råd om hur arbetet kan bedrivas för att kunna nå målen.Implementeringen av projektets resultat i Hantera har resulterat i en ny modul, där projektets områden visualiseras på ett innovativt och användarvänligt sätt. En av de nya funktionerna möjliggör jämförelser emellan organisationer!

Alternative protocols for the production of more sustainable agar-based extracts from Gelidium sesquipedale
- 2021
-
Ingår i: Algal Research. - : Elsevier B.V.. - 2211-9264. ; 55

Tidskriftsartikel (refereegranskat)abstract
- Agar-based extracts from Gelidium sesquipedale were obtained by applying a conventional hot water treatment and alternative ultrasound- and microwave-assisted methods, with and without the application of an alkaline pre-treatment. The alkaline pre-treatment produced refined extracts with higher purity; however, extraction yields increased from 2–5% to 7–19% by omitting this step. In particular, the ultrasound-assisted extraction allowed reducing 4-fold the extraction time, while keeping constant or even increasing the yield (up to 19% for the 1 h extraction) with respect to the conventional protocol. Interestingly, the presence of proteins and polyphenols conferred the semi-refined extracts a relatively high antioxidant capacity (19–24 μmol TE/g extract). The refined extract produced by the standard protocol formed the strongest hydrogels (>1000 g/cm2). On the other hand, the semi-refined extracts produced by the alternative protocols formed slightly stronger hydrogels (337–438 g/cm2) than the refined counterparts (224–311 g/cm2), due to their greater molecular weights of the former ones. LCA assessment showed lower global warming potential for the semi-refined extracts, especially the ultrasound-assisted extraction, hence highlighting the potential of this method to produce more sustainable agar-based extracts for food-related applications.

Swedish Life Cycle Center Livscykeldata - en förutsättning för hållbar innovation, (Life cycle assessment data – a prerequisite for sustainable innovation)
- 2016

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- ”Life Cycle Assessment Data - a prerequisite for sustainable innovation” is an agenda which demonstrates the benefits of a common national strategy for life cycle assessment data (LCA data). LCA data can be used by orga- nizations to measure, follow up and reduce environmental impact. LCA data can also be used to ensure credible and reliable marketing of environmental performance. Increased availability of reliable LCA data has the potential to strengthen Swedish competitiveness on the international market and make Sweden a more attractive country in which to perform operations. It has become clear throughout the project that there is a need for LCA data in Sweden. Environmental authorities, government agencies, municipalities, companies and academia among others have been identified to be in need of LCA data. The most commonly sought data concerns energy production, transport, commodity produc- tion and waste management. The publishing of collected data results in a potential gain, where data can be reused and individual businesses can avoid recollecting the same data. Small businesses that lack the means to acquire data and businesses in the public sector that can use data in public procurement to achieve their environmental goals, have been identified as the ones in most need for open (free) data. The public sector is advised to lead the way by publishing LCA data describing their own businesses, such as municipal energy companies. The UN is governing an extensive intergovernmental cooperation in order to link existing LCA databases into a single information network. Although Sweden have not yet contributed with any concrete data, Swedish participants are currently active in this cooperation. The proposed strategy includes identifying national reference data, that is, quality assured data representative of the Swedish operations, which can meet the needs of a large group of stakeholders. Reference data enables the focus of discussion to shift from which data are applicable to manage the environmental issues of concern. Through a joint process, unnecessary work can be avoided for organizations that are in need of comparable data. Procedures and requirements for how the data will be managed needs to be agreed upon. There are a number of key stakeholders in Sweden who have the knowledge and skills necessary to design a reference data system. Other countries have already implemented such systems and can function as role models. Securing of funds for collection, compilation, publication and provision of data is needed, while details are yet to be determined at the time of publication of this agenda. The lack of a clear political affiliation of the life cycle thinking is a challenge, as it links the environment, industry, and society together. The lack of understanding for the potential of open data in general and a lack of understanding for the benefits of LCA data in particular represents some of the identified obstacles in this agenda. Further obstacles includes that the benefits are spread over several, sometimes weak stakeholders, and that data need to reach a critical mass to become really useful. By making national reference data available to the public the chances increase significantly for all companies and organizations operating in Sweden to increase awareness of their products and services from a life cycle perspective. This is a prerequisite for achieving real sustainable solutions throughout the value chain. (Swedish Life Cycle Center, Report no. 2016:5)

Seafood Life Cycle Inventory database : Methodology and Principles and Data Quality Guidelines
- 2018

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- En växande insikt om betydelsen av livsmedel för global miljöpåverkan, särskilt animaliska livsmedel inklusive sjömat, har lett till ett behov hos producenter såväl som handeln att kommunicera miljöpåverkan av råvaror och produkter genom livsmedelskedjan. Detta visar sig i form av nya krav på att dokumentera produkters miljöavtryck, t ex vid certifiering och i regelverk. EU initiativet inom hållbar utveckling med en "inre marknad för gröna produkter" är ett exempel, med målet att dokumentera miljöavtrycket av produkter på EU marknaden enligt metoden Product Environmental Footprinting (PEF). Målet är att göra det möjligt för konsumenter, handel, producenter och lagstiftare att göra medvetna val och att etablera drivkrafter mot reducerad miljöpåverkan i produkters värdekedja.För att kunna leva upp till dessa nya krav, krävs tillgång på representativ data av hög kvalitet, något som i stort sett har saknats för sjömatsprodukter. För att göra högkvalitativa, representativa data kring resursåtgång och miljöpåverkan av sjömatsprodukter (inklusive biomassa som direkt eller indirekt används till foder) tillgängliga, initierade den norska sjömatsbranschen ett pilotprojekt. Projektet definierade en rekommenderad metod och struktur för datainsamling och använde denna metod för att samla in tillgängliga data för ett antal pilotfall. Metoden för datainsamling presenteras i detta dokument och kan, tillsammans med pilotdataseten som gjorts tillgängliga i projektet, användas av näringen som grund för en bredare datainsamling för att skapa en utbyggd sjömats-LCI-databas.
