1. 1. Exploring the sustainability potential of an algae-based wood adhesive : Comparative and explorative environmental life cycle assessment of algae- vs. formaldehyde- based adhesives for particleboard production

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Charlotte Rasche; [2020]
   Keywords : life cycle assessment; particleboard; bio-adhesive; wood-adhesive; bio-resin; algae; macroalgae; seaweed; kelp; formaldehyde; greener production; environmental impacts; biobased; design for the environment;

   Abstract : Adhesives used for wood composites such as particleboard are conventionally of petrochemical nature with formaldehyde as a base substance and represent a pain point in the industry due their toxic emissions. Consequently, adhesives are subject to an agenda to develop more benign, low-impact alternatives. READ MORE

3. 2. Comparison of in-situ bioremediation of soil contaminated with chlorinated hydrocarbons

   University essay from Högskolan i Halmstad

   Author : Tianyu Qin; [2020]
   Keywords : bioremediation; biostimulation; bioaugmentation; product; chlorinated hydrocarbon;

   Abstract : In recent years, due to the continuous development of machinery, electronics, leather, chemical companies and dry-cleaning industry, more and more chlorinated hydrocarbons accumulate in the soil, causing serious harm to the environment. The accumulation of chlorinated hydrocarbons and the teratogenic, carcinogenic, and mutagenic hazards seriously threaten human health. READ MORE

4. 3. Groundwater denitrification by fluidized bioelectrochemical systems

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Lena Bonin; [2020]
   Keywords : Bioelectrochemistry; fluidized bed reactor; bioremediation; denitrification; groundwater; reduced graphene oxide;

   Abstract : Groundwater (GW) accounting for most of the freshwater available around the World, finding sustainable techniques to depollute it is of crucial importance for safe drinking water supply. The extensive use of fertilizers in the agriculture, as well as other anthropogenic activities, are contributing to the excessive nitrate levels in some aquifers. READ MORE

5. 4. Analysis of metatranscriptomes from an acidophilic electricity generating community treating acidic mining wastewaters

   University essay from Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

   Author : Daniela Palma; [2018]
   Keywords : Acidophiles; extremophiles; MFC; metatranscriptomic; bioinformatics; electricity production; AMD.;

   Abstract : Human ́s constant need for metals requires unsustainable mining and refining of metalore. As a result, highly contaminated wastewaters are discharged in the environmentcompromising the nearby habitat together with all its life forms. READ MORE

6. 5. Evaluation of stimulated reductivedechlorination in situ of chlorinatedsolvents at a site in Huddinge : using principal component analysis, partialleast square regression and degradation

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Karin Ljungberg; [2018]
   Keywords : Reductive dechlorination; DNAPL; stimulated bioremediation; chlorinated solvents; Reduktiv deklorering; DNAPLS; stimulerad biologisk behandling; klorerade lösningsmedel;

   Abstract : The method of using stimulated reductive dechlorination when remediating sites contaminated with chlorinated solvents is not unusual, but not many studies have been done on the overall process outside of a controlled environment. In order to investigate the process, principal component analysis (PCA) and partial least square (PLS) regression was used to identify the most important parameters for the degradation of the chlorinated solvents.
