1.Self-employed 'scrappers' collect waste from the streets and sell it to him. (自營商)

2. Scrappers with lorries earn £800 a day. (有加s)

3. The yard turns over 200 tonnes of scrap metal each week and pays out £60,000 a week to an army of self-employed scrappers, who scour London's streets for rubbish they can turn into cash. (如果這世界上有1人army，那成員大概就是藍波，可以一個人扛200噸的廢棄物)
