   Abstract : Fire load, the total thermal energy released by the combustion of a material, is an essential part of determining a building’s fire performance and the associated fire protection strategies. Elements in a structure are typically categorized into two types of fire loads: permanent and temporary. READ MORE

6. 5. Characterization of Compost from Reusable Industrial Streams: : physical, Nutrient, and Microbial Properties

   University essay from SLU/Dept. of Biosystems and Technology (from 130101)

   Author : Ellen Ek Moreau; [2023]
   Keywords : Spent mushroom compost; apple orchard waste; soil amendment; compost optimization; circular agriculture;

   Abstract : The increasing global population, combined with soil degradation, poses challenges to food security, and raises concerns about the excessive and long-term use of conventional fertilizers. Evaluating sustainable alternative by-products for their soil-improving properties could offer a potential solution, particularly for Swedish fruit producers who can tap into local waste streams as a circular source of plant nutrients.
