The shredding room was a room full of noise and with a chemical smell. The ground was full of plastic bottles and parts of jerrycans. One of the operators of the machine gathered all the waste in a big bucket, while the other pushed all the waste through the machine. He used a bottle instead of his hand for the pushing. When seeing the bottom of the bottle shattered, I understood why.
No words were needed in the room. Both of the operators worked in complete silence, knowing that this was their job and more was not asked for. It looked like an industrial machine, disassembled and divided over several buildings, with people manually operating the parts.
