It was learned from Weichai Remanufacturing Company that in 2013 the company's output reached an annual growth of 45%, which led remanufacturing to a new level. Remanufacture is the use of new technologies to repair and remanufacture old and used engines. As old as new, its power, economy and warranty period are exactly the same as those of new machines. This is a low-cost, recyclable manufacturing mode. In 2008, Weichai Power (Weifang) Remanufacturing Co., Ltd. was established and is one of the 14 pilot companies for the remanufacturing of auto parts in China. As a wholly-owned subsidiary of Weichai Power, remanufacturing companies specialize in the remanufacturing of engines and their parts and components. The total investment of the project is close to 300 million yuan. In March 2009, the first phase of the Weichai remanufacturing technical transformation project was completed, the new plant was put into use, and the remanufactured engines were mass-produced and mechanized. In March 2010, the second phase of the Weichai remanufacturing technical transformation project was completed, and the processing line and assembly line were put into use. At present, Weichai Remanufacturing Company has already included 19 types of models in the pilot product catalog for remanufacturing auto parts. BPS and BPF have been detected in many everyday products, such as personal care products (e.g., body wash, hair care products, makeup, lotions, toothpaste), paper products (e.g., currency, flyers, tickets, mailing envelopes, airplane boarding passes), and food (e.g., dairy products, meat and meat products, vegetables, canned foods, cereals). BPS, BPF, and BPA have been detected in indoor dust at the following concentrations: BPS, 0.34 μg/g; BPF, 0.054 μg/g; BPA, 1.33 μg/g . BPS and BPF have also been detected in surface water, sediment, and sewage effluent, generally at lower concentrations than BPA, but in the same order of magnitude . In humans, BPS and BPF have been detected in urine at concentrations and frequencies comparable to BPA. In urine samples from 100 American, nonoccupationally exposed adults, found BPF in 55% of samples at concentrations up to 212 ng/mL, and BPS in 78% of samples at concentrations up to 12.3 ng/mL. BPA was found in 95% of the samples, with concentrations up to 37.7 ng/mL.
