  1. 1. Changes in lake-water organic carbon over recent centuries in northern Sweden, Västerbotten : Past and present mechanisms, and the potential implications on mercury

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Magnusson Petter; [2023]
    Keywords : Lake-water TOC; Summer forest farming; traditional agriculture; land-use; geochemistry; mercury;

    Abstract : Due to the current increase in lake water total organic carbon (LW-TOC), many studies have investigated the long-term dynamics using lake sediments. However, these have mainly been focused on Sweden’s south and south-central parts. READ MORE

  4. 3. Production of polymers from a papermills wastewater using HTC substrate. : Investigating the viability of using wastewater sludge from Skoghalls’ papermill in combination with filtrate from HTC of sewage sludge to produce biological plastic producing polymers.

    University essay from Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

    Author : Regan George; [2023]
    Keywords : PHA; HTC-substrate; Polymer;

    Abstract : Since their conception, plastics have been a dominant product due to the versatility of use, and readily available raw materials. However, the production and consumption of synthetic plastics have continued to increase over the years, leading to a significant rise in plastic waste and its associated environmental impacts, such as the detrimental effects plastic waste has on ecosystems, including the presence of toxic microplastics and risks to marine life, are becoming the focus of criticism.

  6. 5. Total Organic Carbon Reduction of Sorting by-Product Fractions

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Ahmad Abdul Rahman Al Saheb; [2020]
    Keywords : Total organic carbon; Loss on ignition; construction and demolition waste; TOC reduction; recycling; sequential separation treatment; converting waste to product;

    Abstract : The drive of the EU countries and most of the world towards a circular economy and togenerate zero waste raised a need to study more efficient and less costly treatment processes. The treatment of secondary and by-product fractions to convert them from what is considered waste to a resource will contribute to the movement towards zero waste and circular economy. READ MORE
