1. Stabilization of fine-grained soils in cold environment and exposed to seasonal frost : By-products as hydraulic binders
Sammanfattning : This doctoral thesis deals with the stabilization of fine-grained soils using by-product originated hydraulic binders. The use of fine-grained soils as subsoil for infrastructure projects is often limited because of the risk for instability. LÄS MER
2. Development of Methods for Analysis of Valuable Compounds in By-products from Agricultural and Forestry Industrial Sectors
Sammanfattning : A growing interest in sustainable development has made efficient utilisation of starting materials and, if they occur, by-products become increasingly important. Vast amounts of by-products are generated by the forestry and food industry. LÄS MER
3. Recycling of metallurgical by-products within integrated iron and steelmaking : experimental studies of cold bonded by-product pellets
Sammanfattning : In recent years as costs for depositing dust and sludge generated in the iron and steel making industry have increased, due to lack of space and increasing environmental restrictions, the need to recycle these solid by- products to avoid depositing costs and to recover valuable metal fractions, is soon becoming a necessary reality. Cold bonded agglomeration is considered to be a well-suited alternative for recycling of steel industry by-product dust and sludge. LÄS MER
4. Alkaline by-products as amendments for remediation of historic mine sites
Sammanfattning : Mining has been and still is an important industry in Sweden, it has strongly contributed to the standard of living we have today. Extraction of ore began in the 12th century, but did not come about frequently until the 16th century, which is often seen as the starting age for ore processing and metal extraction. LÄS MER
5. Studies in low temperature self-reduction of by-products from integrated iron and steelmaking
Sammanfattning : Within the last decade, the landfill tax in Sweden has increased over 70% with comparable rates in the UK and elsewhere in EU. This development, among others, highlights the incentive for increased recycling efforts of fine particulate solid by-products in the iron and steel making industry in order to avoid depositing costs and to recover valuable metal fractions.
