1. 1. Interest in Material Cycle Closure? Exploring Evolution of Industry's Responses to High-grade Recycling from an Industrial Ecology Perspective

   Författare :Philip Peck; Internationella miljöinstitutet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; polymers; vehicles; ELV; extended producer responsibility; chemical recycling; material cycling; material flows; closed-loop recycling; Industrial Ecology; recycling; aluminium.; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

   Sammanfattning : Many anthropogenically-produced or beneficiated materials contained in “end-of-life” products retain a great proportion of the invested manufacturing work when discarded. Very few such materials are reconstituted and applied in new products at the same material inherent quality level as in their first lifetime – a process known as “closed-loop recycling”. LÄS MER

3. 2. Recycling of concrete in new structural concrete

   Författare :Madumita Sadagopan; Andrzej Cwirzen; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete recycling; sustainability; closed-loop recycling; recycled aggregates; compressive strength; workability mechanical pre-processing; secondary cementitious materials; green concrete; climate-optimized concrete; Resource Recovery; Resursåtervinning;

   Sammanfattning : Concrete waste as crushed concrete aggregates (CCA) in structural concrete gives a new purpose and prolongs the technical life of the reference concrete accomplishing closed loop recycling. This research investigates CCA as aggregate replacement in an industrial reference concrete recipe as fine aggregate fractions and overall aggregate replacement. LÄS MER

4. 3. Closed-loop strategy for recycling of starch and poly (lactic acid) into new materials

   Författare :Duo Wu; Minna Hakkarainen; Monica Ek; Martin Lawoko; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Biopolymers such as starch and poly lactic acid (PLA) can be derived from agriculture and are among the most promising biobased plastics for packaging and other short term application. Considering the growing pressure of environmental safety and limited resources on our planet, it would be beneficial to retain the value of waste products by material recycling. LÄS MER

5. 4. Organising Product Recovery in Business Networks

   Författare :Igor Insanic; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; product recovery; industrial networks; remanufacturing; refurbishing; organising; closed loop supply chain management; waste management; activity coordination; transvection; resource combining; recycling; reverse logistics; reverse supply chain; recycling; sorting;

   Sammanfattning : The licentiate thesis includes an analysis of different ways of organising product recovery. The aim of product recovery is raw materials conservation, which is strongly related to sustainable development. LÄS MER

7. 5. Reuse and Recycling of Food Packaging - Odour Related Aspects of the Use and Misuse of PET Beverage Bottles

   Författare :Heléne Widén; Avdelningen för livsmedel och läkemedel; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Livsmedelsteknik; Food and drink technology; aroma transfer; reuse; recycling; migration; contaminants; post consumer material; food packaging; polyethylene terephthalate PET ;

   Sammanfattning : The reuse and closed-loop recycling of food packaging was studied in order to assess consumer safety and the sensory quality (e.g. taste and smell) of packaged food. LÄS MER
