Though the Suzhou government has provided household solid waste (HSW) source separation since 2000, the program remains largely ineffective. Between January and March 2014, the authors conducted an intercept survey in five different community groups in Suzhou, and 505 valid surveys were completed. Based on the survey, the authors used an ordered probit regression to study residents’ HSW source separation activities for both Suzhou and for the five community groups. Results showed that 43% of the respondents in Suzhou thought they knew how to source separate HSW, and 29% of them have source separated HSW accurately. The results also found that the current HSW source separation pilot program in Suzhou is valid, as HSW source separation facilities and residents’ separation behavior both became better and better along with the program implementation. The main determinants of residents’ HSW source separation behavior are residents’ age, HSW source separation facilities and government preferential policies. The accessibility to waste management service is particularly important. Attitudes and willingness do not have significant impacts on residents’ HSW source separation behavior.

Based on the flexural-shear and press-flexural-shear test of four scale HSW model building with High Shear-Span Ratio, The seismic behavior of the slit and integral HSW are discussed, then the failure characteristics and capacity of HSW under Vertical load and seams are analyzed. The result of experimental study proves that the ductility and the property of energy dissipation of HSW are well; Vertical load could increase the capacity and deformation, decrease the energy dissipation of HSW. And the seams of wall could improve the ductility and the property of energy dissipation of HSW , lower the capacity.

In its operations, the Universitas Andalas Limau Manis Campus generates hazardous solid waste (HSW); however, no specific management is in place. This study aims to identify the HSW generated at Universitas Andalas Limau Manis Campus, including analyzing the waste generation rate, composition, and characteristics. Measurements were conducted at 36 sampling points representing office, academic, student, and other campus activities, with a confidence level of 99.92%. The analysis revealed that the specific HSW waste generation rate was 0.56 ± 0.28 g/person/day (0.10 ± 0.03 g/m²/day) by weight or 2.89 ± 1.19 mL/person/day (0.56 ± 0.16 mL/m²/day) by volume. The total HSW generation was 37.59 kg/day (169.68 L/day), accounting for 1.6% of the campus’s total waste. The composition of HSW includes HSW products 0.58%, HSW packaging 23.43%, electronic waste 46.35%, and expired or off-specification HSW products 29.65%. The HSW characteristics identified were toxic 76.70%, corrosive 13.19% and flammable 10.11%. Currently, HSW is mixed with non-HSW and ends up in landfills, except for electronic waste, which is stored in warehouses. This situation poses risks to health and the environment, thus highlighting the need for a specific HSW management plan.
