2. 1. Constructing communities : The establishment and demographic development of sawmill communities in the Sundsvall district, 1850-1890

   Author : Maria Bergman; Sören Edvinsson; Anna Lundberg; Ann-Sofie Högman; Umeå universitet; []
   Keywords : HUMANIORA; HUMANITIES; Sawmill; sawmill worker; Sundsvall; 19th century; community; population development; migration; internal parish migration; barriers; residency; demographic structure; fammily; kinship networks; History; Historia; historia; History;

   Abstract : This dissertation studies the establishment and demographic development of the sawmill communities that emerged in the Sundsvall district during the latter half of the 19th century.  The intention is to highlight the importance of the sawmill communities and their resident populations by discussing community construction from a demographic perspective as well as socially and symbolically.

4. 2. Cost-Effective Pathways for Gasification-Based Production of Biofuels

   Author : Johan Ahlström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomethane; power-to-gas; Biorefinery; SNG; heat integration; bark; Gasification; sawmill; hydrogen;

   Abstract : A considerable number of studies indicate that biomethane produced through gasification of lignocellulosic biomass could contribute significantly to greenhouse gas emissions reduction in the transport sector. However, the production costs are high compared to fossil-based alternatives, which has limited deployment of the technology. READ MORE

5. 3. Sustainable production of bio-energy products in the sawmill industry

   Author : Anna Vidlund; KTH; []
   Keywords : sawmill industry; energy efficiency; heat recovery; integration; biofuel; upgrading; district heating; fuel pellets; CHP; VOC; CO2;

   Abstract : One of the great challenges facing society is to convert theglobal energy system to a sustainable process. Currently, 80%of the world´s energy is supplied through the combustionof fossil fuels. Not only are the fossil resources limited, theutilisation also increases the level of greenhouse gases in theatmosphere. READ MORE

6. 4. Shaping Future Opportunities for Biomass Gasification - The Role of Integration

   Author : Johan Ahlström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen; heat integration; Gasification; sawmill; SNG; power-to-gas; Biomethane; Biorefinery; process integration;

   Abstract : A considerable number of studies indicate that biofuels produced from lignocellulosic biomass will most probably play a significant role in achieving the climate goals stated in the Paris agreement. Several candidate technologies could be implemented to produce these fuels, and one of the most promising is thermal gasification. READ MORE

7. 5. Customers' logistics service requirements and logistics strategies in the Swedish sawmill industry

   Author : Åsa Gustafsson; Anne Toppinen; Växjö universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Logistics strategy; House-building industry; Retail industry; Sawmill industry; and Service requirements; Forest economics; Skogsekonomi;

   Abstract : The future of the sawmill industry is uncertain; this is partly due to its internal structural changes, but also due to structural changes amongst their customers. Concurrently, competition within the industry is increasing, and therefore focus is constantly being placed on reducing costs and leveraging economies of scale. READ MORE
