- Description
The following thesis intends to analyze the re-use of the residual waste as a resource to generate energy. The thesis explains how to characterize and assess the output of the low calorific fraction from a mechanical treatment plant focus on the organic matter. Thereafter, different co-substrates from the low calorific fraction were analyzed to find their biogas potential. This thesis project took place in the city of Innsbruck in Austria in 2014, and it was a joint work between University of Oldenburg and University of Innsbruck. The thesis was part of the project E02EneRAlp II (Energy in the Alps) Project F (Small organic fraction from residual waste as possible sustainable energy resource and raw material resource) which is founded by CoMET (Competence Centers for Excellent Technologies) K1-Center. The waste samples analyzed were taken from the mechanical treatment plant of Ahrental and the sludge samples from the wastewater treatment plant of Zirl both in Austria. The experiments were carried out in the laboratory of the Department of Environmental Engineering at Innsbruck University during four months. In the thesis was analyzed the biogas potential of co-substrates from the output of the low calorific fraction with the sludge from the wastewater treatment plant. The results have shown that the fraction of less than 10 mm of the low calorific fraction has the highest biogas production per mass of volatile solids with 309 Nl BG/kg VS, and the co-substrate with highest annual biogas potential is the negative sorting co-substrate, which takes 20% of the plastic and high-density material, with 2.65 x 10 6 Nm?. The results have shown that low calorific fraction can be used as co-substrate to enhance the biogas production after it is undergone to a treatment process which takes out all contraries that cause a problem in the digestion process.
