Abstract: With the increasing of sludge emissions and people''s increasing demand for better dwelling environment, resource utilization of sludge receives much concern in recent years. Currently, the co-processing of sludge in cement kiln has been considered as a sustainable way to dispose sludge in Japan as well as Europe and the United States. Huaxin has begun the co-processing of sludge in cement kiln since 2008. So far, 65000 tons of sludge has been successfully disposed. This paper focus on 3 ways of co-processing sludge in cement kiln through certain project examples. [Copyright &y& Elsevier]

Background: The difference in epidemiological characteristics of breast cancer (BC) across countries is valuable for BC management and prevention. The study evaluated the up-to-date burden, trends, and risk factors of BC in China, Japan and South Korea during 1990-2019 and predicted the BC burden until 2034., Methods: Data on incident cases, deaths, disability-adjusted life-years (DALYs) and age-standardized rate (ASR) of BC were extracted from the Global Burden of Disease Study 2019. Trend analysis and prediction until 2034 were conducted by estimated annual percentage change and a Bayesian age-period-cohort model, respectively. Besides, the attributable burden to BC risk factors was also estimated., Results: In 2019, the number of BC incident cases, deaths and DALYs in China were 375,484, 96,306 and 2,957,453, respectively. The ASR of incidence increased, while that of death and DALYs decreased for Chinese females and Japanese and South Korean males during 1990-2019. High body-mass-index (BMI) was the largest contributor to Chinese female BC deaths and DALYs, while alcohol use was the greatest risk factor for Japanese and South Korean as well as Chinese males. The incident cases and deaths were expected to continue increase during 2020-2034 (except for Japanese female incident cases)., Conclusions: China had the greatest burden of BC among the three countries. Incident cases and deaths of BC were projected to increase over the next 15 years in China, particularly among Chinese males. Effective prevention and management strategies are urgently necessary for BC control in China., (© 2022. The Author(s).)
