217 12. International <strong>best</strong> <strong>practices</strong> 12.1. The SUMTER plant in South Carolina, USA In the city of Sumter two are existent problems in waste management. These are sewage sludge <strong>and</strong> waste wood, mainly tree bark from industry operating in the region. Picture 71.: Sumpter drying plant The problem was solved by producing energy from the woodchips in order for the sewage sludge to be dried. The sludge is used in agriculture as a fertilizer. The plants specification are: storage area for wood <strong>and</strong> bark waste shredding equipment for waste wood front loader <strong>and</strong> weighing device buffer silo for wood/bark combined grate firing with lean gas combustion (1000°C hot gas) with automatic ash discharge directly fired st<strong>and</strong>ard drum drying plant for evaporation of 4 t liquid/hour, approx. 5,500 tones d.s. annually, with sewage sludge predewatered to 15% d.s. (digested). Alternatively, the drying plant can be operated partially or entirely with primary energy. At the following figure the process that takes place in the plant can be seen (Figure 57.):
218 Figure 56.: Process description 12.2.The ARTI Compact Biogas System used in Tanzania <strong>and</strong> Ug<strong>and</strong>a . The ARTI (Figure 58.) Compact biogas system (CBS) is made from two cutdown st<strong>and</strong>ard high density polyethylene (HDPE) water tanks <strong>and</strong> st<strong>and</strong>ard plumber piping. The larger tank acts as the digester while the smaller one is inverted <strong>and</strong> telescoped in to the digester <strong>and</strong> serves as a floating gas holder, which raises proportional to the produced gas <strong>and</strong> acts as a store room of the biogas. The CBS is designed for treating 1-2kg (dry weight) of kitchen waste per day. The gas can directly be used for cooking on an adjustable gas stove whereas the liquid effluent can be applied as nutrient fertilizer in the garden. Space of about 2 m 2 <strong>and</strong> 2.5 m height is needed for a CBS of 1000l.( Riuji., 2009)
