   Sammanfattning : In off-grid holiday homes, alternative toilet solutions are needed. There is a wide range of dry toilet systems, where urine-diverting systems and incineration toilets are common solutions. Urine-diverting dry toilets require that users need to manage generated fecal fractions.

3. 17. Bokashis respiration i jorden : betydelse för dess klimatpåverkan

   Kandidat-uppsats, SLU/Dept. of Soil and Environment

   Författare :Rebecka Thorslund; [2020]
   Nyckelord :Bokashi; CO2; effektiva mikroorganismer; kompost; respiration;

   Sammanfattning : Idag är det enbart 38 % av Sveriges matavfall som tas till vara på ett sådant sätt att växtnäringsämnena nyttjas. Avfallshanteringen av matavfall kan därför få en betydande roll för näringskretsloppet och därmed även kolkretsloppet. LÄS MER

4. 18. Innovative agricultural intensification to cope with demographic and climatic changes for subsistence producers : a case study of Sandfly Island, Solomon Islands

   Master-uppsats, SLU/Dept. of Soil and Environment

   Författare :Matthieu Michelet; [2020]
   Nyckelord :Subsistence agriculture; fallow; mulching; composting; innovative intensification; Melanesia; climate change;

   Sammanfattning : This research aims to study the dynamics of agricultural intensification amongst the small island community of Sandfly Island, Solomon Islands, and to observe the spreading of new agricultural practices of intensification that can help mitigate the pressures of climate change on the one side; and on the other side of a growing food demand from a growing population. The intention is to describe the variety of agricultural practices and the variation of production parameters such as fallow length, length of cropping period, number of plots in agricultural rotation and size of plots as to assess the state of agricultural intensification and to find what are the environmental constraints to production.

5. 19. Fly larvae composting of fibrous food industry waste : impact of pre-treatment

   Master-uppsats, SLU/Department of Molecular Sciences

   Författare :Robert Almqvist; [2020]
   Nyckelord :fly larvae; composting; BSFL; waste; recycling; larvae;

   Sammanfattning : With increasing population worldwide comes higher demands of food and greater waste generation. Effective ways for safe nutrient recycling and waste treatment are thus needed to minimize the human impact on the environment. LÄS MER

7. 20. Developing Dog Biscuits from Industrial by-product

   Master-uppsats, Lunds universitet/Förpackningslogistik

   Författare :Kyriaki Chanioti; [2019]
   Nyckelord :circular economy; waste recovery; upcycling; sustainability; product development; Agriculture and Food Sciences; Technology and Engineering;

   Sammanfattning : Have you ever wondered how we can reduce food waste and at the same time provide a more sustainable and eco-friendly environment to all of us? One of the United Nations goals is to bring by 2030 more responsible consumption and production to the environment. Industries are paying annually for solid waste disposal up to 16,000€ and at the same time, the most preferred way to dispose it is through landfill and composting. LÄS MER
