   Abstract : Out of the 17 Sustainable Development Goals (SDGs) adopted by the United Nations in 2015, chemicals and waste management are obtainable under six. Improper and unsafe disposal of toxic chemicals into the environment affects life below water (SDG 14), human health and well-being (SDG 7), and clean water and sanitation (SDG 6). READ MORE

3. 2. Anaerobic Co-digestion of steam pretreated wheat straw and sewage sludge

   University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

   Author : Virginia Tosi; [2021]
   Keywords : Anaerobic co-digestion; wheat straw pretreatment; nutrients availability; OLR; VFA acumulation; Biotechnology; Technology and Engineering;

   Abstract : Anaerobic digestion (AD) of wastes and residues is a widely applied and explored process. However, when the process is not optimized, inadequate concentrations of nutrients and inhibitory compounds are common and can lead to low maximum organic loading rates and increased risk of process problems, low organic dry solids degradation rate and reduced methane yields.

6. 5. A case study in consolidating the loss structure of different manufacturing sectors under lean context

   University essay from Lunds universitet/Produktionsekonomi

   Author : Hua Tong; Thi Minh Trang Dao; [2020]
   Keywords : Lean Manufacturing; Loss Deployment; Loss Structure; World Class Manufacturing WCM ; Technology and Engineering;

   Abstract : In the light of lean methodology, World Class Manufacturing requires continuous improvement in analyzing the losses to eliminate the wasteful resources and to boost the overall productivity. However, the standardized loss structure should be well-balanced to be general enough to cover the whole manufacturing procedure while being specific enough to point out the real issues happening for further improvement.
