1. 1. Advances in Ventilation Heat Recovery : An assessment of peak loads shaving using renewables

   Författare :Behrouz Nourozi; Sasan Sadrizadeh; Adnan Ploskic; Carey Simonson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Peak heat load shaving; renewable energy; ventilation heat recovery; frosting in heat exchangers; Heat transfer; förnybar energi; ventilation värmeåtervinning; frosting i värmeväxlare; värmeöverföring; Byggvetenskap; Civil and Architectural Engineering;

   Sammanfattning : The building sector accounts for approximately 40% of total global energy usage.In residential buildings located in cold climate countries, 30-60% of this energy isused for space heating, 20–30% is lost by discarded residential wastewater, and therest is devoted to ventilation heat loss.

3. 2. Sustainable building ventilation solutions with heat recovery from waste heat

   Författare :Behrouz Nourozi; Sture Holmberg; Adnan Ploskic; Qian Wang; Shia-Hui Peng; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater heat recovery; balanced mechanical ventilation; defrosting reduction; heat recovery efficiency; thermal load shifting; renewables; Byggvetenskap; Civil and Architectural Engineering;

   Sammanfattning : The energy used by building sector accounts for approximately 40% of the total energy usage. In residential buildings, 30-60% of this energy is used for space heating which is mainly wasted by transmission heat losses. A share of 20-30% is lost by the discarded residential wastewater and the rest is devoted to ventilation heat loss. LÄS MER

4. 3. Waste Heat Driven Membrane Distillation for Industrial Wastewater Treatment

   Författare :Imtisal-e- Noor; Andrew R. Martin; Olli Dahl; Mikel Duke; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane Distillation; Experimental investigations; Techno-economic; Wastewater; Flue gas condensate; Waste heat; District heating; Nano-electronics; Cogeneration; Sustainable development; Energy Technology; Energiteknik; Chemical Engineering; Kemiteknik;

   Sammanfattning : The European Union has placed a high priority on reaching the goals described in the 2030 Agenda for Sustainable Development. This aim has provided added momentum to member-state environmental regulatory authorities to further tighten the discharge limits of industrial wastewater. LÄS MER

5. 4. Integrated sewage sludge treatment scenarios – techno-economic analysis on energy and phosphorus recovery

   Författare :Marzieh Bagheri; Elisabeth Wetterlund; Marcus Öhman; Lale Andreas; Roozbeh Feiz; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sewage sludge management; techno-economic analysis; phosphorus recovery; thermochemical treatment; Energy Engineering; Energiteknik;

   Sammanfattning : Sewage sludge is a by-product of wastewater treatment that simultaneously gathers contaminants, valuable organic matter, and nutrients. The treatment of the increasing amount of sewage sludge is important from both pollution prevention and resource recovery perspectives as i) large shares of mineral phosphorus, listed as a critical raw material, terminate in the sewage sludge, and ii) energy recovery from sewage sludge can cover the energy-intensive demand of the treatment process.

7. 5. Process Utility Performance Evaluation and Enhancements in the Traditional Sugar Cane Industry

   Författare :Eyerusalem Deresse Birru; Andrew Martin; Catharina Erlich; Hailong Li; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sugar cane; energy saving; heat loss; steady state; transient state; CO2 emission; absorption chiller; pellet; bagasse drying; energy perfor-mance; traditional mills; modern mills; waste water; surplus power; Energy Technology; Energiteknik;

   Sammanfattning : The need to achieve sustainable development has led to devising various approaches for the efficient utilization of natural resources. Renewable energy technology and energy efficiency measures feature prominently in this regard, and in particular for industries such as sugar production:  the sugar cane industry’s eponymous feedstock is a renewable resource, and mills have potential for increased energy savings via improvements to cogeneration units, electric drive retrofitting, and other measures.
