Solar Assisted Pervaporation (SAP) is a novel technique of preservation that combines the concept of membrane separation and the use of solar energy. The method uses a ‘breathable pouch’ with an active layer of a food-grade hydrophilic membrane. The aim of this study was to understand how different drying temperatures (50oC and 60oC), air exclusion treatment (with and without vacuum) and type of
The purpose of this study is to investigate how and to what extent four different sustainability certifications set standards for conserving or promoting biodiversity. This is of importance since there are a large number of certifications of different kinds on the market and as a consumer it can be difficult to navigate among these. How these certifications favor biodiversity is important to inves
Climate change, the energy crisis of 2022-2023, and estimations of future electricity demands have stressed the necessity for a rapid transition of the energy system. Offshore wind energy plays an important role in this transition, and is expected to expand considerably on a global level, in the EU and in Sweden. While Swedes show high support of wind energy, a majority of recent projects have bee
Food production is a major driver of climate change and environmental degradation. There is a political will to use public procurement as a strategic tool to promote more sustainable practices in the food industry. There are many aspects of sustainable food consumption, and one aspect that is getting increased attention is locally produced food. This study aims to examine how municipalities in the
The decline of bees, such as bumblebees, over the last decades raises concerns as they are key pollinators in both agricultural and natural ecosystems. One proposed cause for the decline of wild bees is competition for food resources with managed honeybees. Detrimental effects of competition can result where co-existing species exhibit a high degree of shared resource use (i.e., niche overlap). Th
Polybrominated diphenyl ethers (PBDE) and hexabromocyclododecane (HBCDD) are brominated flame retardants. These compounds are lipophilic, persistent and have been shown to bioaccumulate. The Baltic grey seal (Halichoerus grypus) and the Eurasian otter (Lutra lutra) are top predators and especially exposed to high levels of lipophilic pollutant in their diet due to biomagnification. In the current
Perceptions have the capacity of indirectly shaping agendas and affecting behaviours. It is a concept briefly touched upon in peacebuilding research, as a tool of tracing dominant practices of international interveners. This paper aims to contribute to this literature, by analysing how perceptions of the UN relate with lacking local agency in peacebuilding practice. In a case study of MONUC’s inte
Electronic waste is the fastest growing waste category, seen as a consequence of the industry’s rapid technological advancement. The waste in this industry is problematic due to the inherent heterogenic property of devices, the toxicity of the waste, as well as resource intensive production of the required materials. To decrease this waste and the resource demand in the production of electrical de
Emissions from drained organic soils is a big contributor to global warming and corresponds to 5% of global and 25% of Sweden’s greenhouse gas (GHG) emissions. This study uses a GIS-analysis to map the organic soils in Kristianstad municipality in Sweden and what land use occurs on these soils. The purpose of the study is to provide the municipality with information when investigating the possibi
Packaging waste is an active environmental problem. There is an ongoing process of change in both the EU and Sweden to reduce the amount of packaging waste and create more resources for a circular flow. Considering this, there are contexts, despite new legislation, where single-use packaging will still be offered. Therefore it becomes significant to understand how the consumer can be influenced in
Environmental pollution caused by human activity is one of today's biggest dilemmas. Pollution in air, water and soil can pose risks to human health and the environment and can lead to a reduction in available resources. Investigating and remediating contaminated areas is therefore an important task. In the past 20 years, there have been two major spills of gasoline and diesel at the Energy Po
This study aims to investigate the ecological sustainability of different beverage packaging and compare this to consumers’ perception of the most environmentally friendly packaging type. A literature analysis was made to understand the advantages and disadvantages of different packaging as well as consumer behavior from other surveys in other studies. Lastly this study conducted and preformed its
To continue the development of novel therapeutics to treat bladder cancer, a reliable model for preclinical testing of treatments and studying of the disease mechanism is essential. Ex vivo culturing of precision cut tumor slices (PCTS) provides a model that can retain the tumor architecture and its tumor microenvironment including the immune cell compartment, but data on PCTS based on bladder tum
To meet climate objectives our society needs to be more resource efficient, and a circular economy is part of the solution. Maintaining and repairing products to prolong their lifetime is usually better than replacing the product. In Sweden there are existing economic policies such as value added tax and tax reductions that incentivize the consumer towards prolonging the life of their products, bu
Due to the growing e-commerce volumes, product returns have become an increasingly important issue within the fashion industry. About 70 % of all returns are caused by poor fit or size. Therefore, there is a need to improve fit and size information online to decrease the rate of returns. In recent years, there has been an increased interest for implementing AI solutions to improve consumer informa
The Greenhouse Gas Reduction Mandate (GGRM, reduktionsplikten) is Swedish legislation focused on reducing carbon emissions by mandating that the emissions of certain fuels are reduced by a specified percentage, that percentage increasing each year. This paper investigates the rationale behind a political drive to decrease the GGRM, the cost-effectiveness of the GGRM, and the consequences of t
The ongoing climate changes pose a serious threat to both societies and ecosystems globally. Intensification of extreme weather, floods in combination with heat waves and droughts are some of the challenges that require adaptable and sustainable solutions. Nature-based solutions (NBS) have been identified as a powerful tool for creating resilient and sustainable cities by integrating natural proce
The European union and the Convention on biological diversity require 30% of all land to be protected by 2030, stressing the necessity for increased nature conservation. To meet the requirements different forms of protection are needed. Thus, nature conservation agreements (NCA) relevant for further exploration, as they are not used in as large of an extent as other nature conservation types. Thi
