1. On circularity in production systems : Exploring the realization through circularity practices
Sammanfattning : The manufacturing industry stands in front of huge challenges. Negative environmental impacts must be drastically reduced and new sustainable products must be introduced at an accelerating pace. Coping with these challenges are significant in order to deal with the increasingly emerging climate crisis. LÄS MER
2. Circularity Assessment of Water and Waste in Cities : A Proposed Framework for Sustainable Performance Evaluation using LCA and LCC
Sammanfattning : Urbanization is a global phenomenon, happening on a massive scale and at a rapid rate, with 68% of the planet’s population predicted to be living in cities by 2050 (UN-DESA, 2018). The sustainability of a city (Goal 11 of UN SDGs) undergoing rapid urbanization depends on its ability to maintain a low consumption of resources and materials at any given time (referred to as the urban metabolic rate), whilst simultaneously providing essential municipal services to its inhabitants, such as a water supply, wastewater treatment and solid waste management.

3. Energy and Environmental Factors in Food and Beverage Production Systems : An Analysis of Tomatoes, Whisky, and Beer
Sammanfattning : Given the anticipated global population of approximately 10 billion by 2050, the task of ensuring adequate sustenance for all within the constraints of Earth's limited resources presents a significant challenge. The production of food and beverages demands considerable energy investment, as well as other essential resources such as water and nutrients. LÄS MER
4. Circular design in practice: Towards a co-created circular economy through design
Sammanfattning : In the efforts to stimulate sustainable development, the circular economy represents the most recent attempt to reduce the pressure on the environment by attaining harmony between the economy, environment and society. In theory, this is accomplished by establishing ‘closed-loop’ flows of resources in a way that enables businesses and society to reap benefits from maintaining products, components and materials at their highest utility and value, while simultaneously reducing the generation of waste.

5. Sustainable Biobased Protein Superabsorbents from Agricultural Co-Products
Sammanfattning : The preparation of sustainable protein superabsorbents from agricultural industry side-streams is reported. Wheat gluten (WG), a co-product from the ethanol/starch industry, was processed into foams with sponge-like behavior and high liquid uptake. LÄS MER
