  1. 1. Integration of food shelf-life in life cycle assessment of polymers

    University essay from Lunds universitet/Förpackningslogistik

    Author : Divya Sukumaran Nair; [2021]
    Keywords : Food shelf-life; life cycle assessment; biopolymers; food packaging; sustainability; shelf-life induced food waste; Technology and Engineering;

    Abstract : Biopolymers are being considered as a promising alternative to fossil-based polymers and this inclination towards biopolymers is due to their lower environmental impact owing to their origin from renewable resources. The environmental impact assessment, however, often does not consider the impact of barrier properties of polymers and the resulting differences in food waste generated in the supply chain.

Up to 90 % of energy use within the urban water cycle is allocated to hot water heating for end users. READ MORE

  5. 5. Life cycle assessment of hybrid systems for rural electrification in Bolivia

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Sandu Seres; [2021]
    Keywords : Diesel; Stirling; Photovoltaic; impact category;

    Abstract : Bolivia is a developing country in South America. Many rural communities still lack access to electricity. The extension of the National Grid System to all rural communities is not feasible due to economic and topographic challenges as well as the environmental problems that may arise. To tackle these problems, Off-grid solutions are implemented. READ MORE
