    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; environmental systems analysis; waste management; import; local resources; food production; beverage production; circularity; Hållbar stadsutveckling; Sustainable Urban Development;

    Abstract : 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. READ MORE

  6. 4. Anaerobic digestion of horse manure : renewable energy and plant nutrients in a systems perspective

    Author : Åsa Hadin; Ola Eriksson; Karl Hillman; Nils Ryrholm; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Horse manure; horse keeping; anaerobic digestion; nutrient recycling; systems perspective; bedding; methane potential; feedstock; biogas; biofertilizer; Hästgödsel; hästhållning; rötning; näringsåterföring; systemperspektiv; strömaterial; metanpotential; biogassubstrat; biogas; biogödsel;

    Abstract : In horse keeping horse manure is produced, which can be utilized as a fertilizer or considered a waste. Horse manure constitutes a resource in terms of both plant nutrients and energy. In addition energy policies and objectives aim at replacing fossil fuels with renewable energy sources. READ MORE

  7. 5. From waste problem to renewable energy resource : exploring horse manure as feedstock for anaerobic digestion

    Author : Åsa Hadin; Ola Norrman Eriksson; Karl Hillman; Nils Ryrholm; Jaana Sorvari; Högskolan i Gävle; []
