New jobs and dozens of apps have been created to help Shanghai residents find the right bin for their garbage disposal after the strictest waste-sorting rules in the city's history went into effect July 1. /VCG Photo

Residents can make appointments with nearby waste collectors with the 'click' of an app button and wait for their garbage pick-up service at home. It's like ordering express delivery. /VCG Photo

Some garbage collectors provide services for free, but only for recycling waste, such as newspaper, books, carton, plastic bottles, metals and clothing. /VCG Photo

For those who don't have time or don't know how to sort the waste into the four different categories mandated by the new ordinance, garbage collectors can charge two yuan for one collection, or about 500 yuan a month depending on the weight of the waste and the floor where the customer's home is located. /VCG Photo
