Over the past few years, waste management regulations in China have seen immense tightening. The big cities have been subjected to particularly severe restrictions in terms of the sorting and processing of various fractions. For the first time ever, a Chinese customer, Shanghai Old Port Solid Waste, has chosen to shred household waste with the help of a foreign supplier – and two powerful machines from M&J will be doing the job. Shanghai is the largest and most densely populated city in the world (three times bigger than New York), which makes it crucial to have an effective strategy for ensuring that most of the approximately 21,000 tonnes of waste created every day is recycled.

As the largest waste treatment factory in China, Shanghai Old Port Solid Waste is at the forefront of the battle against the ever-growing piles of waste, which are typically delivered in large plastic bags. The two M&J PreShred 4000S-10 machines will be part of an advanced process that involves screening, shredding, wind shifting and optical sorting.

Challenging fractions require the best

The project to shred household waste in Shanghai will pave the way for similar projects in other Chinese cities. Beijing and Shenzhen are on course with similar solutions, and Shanghai Old Port Solid Waste also expects to upgrade with more pre-shredders for other fractions next year. The fact that M&J was chosen as a supplier demonstrates that Shanghai Old Port Solid Waste will not compromise on quality and reliability. The mobile M&J PreShred 4000 is extremely robust and offers impressive performance, a combination that secures its position at the forefront of shredders, with the absolute lowest operating cost on the market. Another benefit that helped in the decision was the homogeneous output size, regardless of the fraction. Shanghai Old Port Solid Waste receives mixed fractions consisting of concrete, brick, glass, metal, bamboo, wood, paper, plastic and textiles, among other things.

The company

Shanghai Old Port Solid Waste Co., Ltd is a joint venture between the French company Veolia, which owns a 60% stake, and the investment branch of the municipal government. The plant began operating in 1989. Since then, it has processed 77 million tonnes of waste, and it processes 14,000 tonnes every day.
