Filling in the gaps

Filling in the gaps THE team analysing the disposal of wastes in landfills is doing pioneering work in that it has not just identified the types of waste being dumped but even segregated the waste, allocating them it) sparate landfills. The waste in these landfills undergoes decomposition by fermentation. The process of decomposition varies in different landfills because bacterial activity may require the fermentation process to be either aerobic or anaerobic in nature.

In an aerobic landfill, a first layer of waste is spread on the ground and oxidied by micro-organistins before decomposition takes place. The fermentation process in the culture medium raises the temperature to roughly 65- 85
