Estimating the public preferences for solid waste management programmes using choice experiments in Macao.

This paper reports on the potential to apply the choice experiment method to understand the public's preferences for solid waste management programmes in Macao. A random sample survey of 260 respondents in Macao was conducted during the summer in 2004. The survey data was analysed using conditional multinomial logit models. The study results indicate that Macao residents prefer: (1) waste segregation and recycling at source; (2) noise reduction during waste collection and transportation and (3) lower garbage fees. The study concludes that choice experiment is a reliable tool in the analysis of respondents' preferences for developing a suitable solid waste management programme in Macao.

Solid waste management in Macao: practices and challenges.

The rapid economic development and population growth in Macao have resulted in a large increase in refuse generated over the past decade. In 2003, the quantity of solid waste generated reached 249,255 tons, corresponding to 1.52 kg/day per capita. This figure has been gradually increasing. Domestic solid waste is the primary source of solid waste generation. The data showed that a considerable amount of the solid waste generated can be recycled and reutilized. Due to Macao's small geographic area and high cost of land, landfilling has the lowest priority for waste disposal. Solid waste incineration has been given a top priority over other waste disposal methods although it is much more expensive. In the last decade, more than 80% of the total waste in Macao was incinerated. However, the incineration capacity of the Macao Incineration Plant is going to reach its saturation earlier than expected. Waste minimization, the establishment of an effective waste collection and disposal fee system, and alternate ways dealing with the limited capacity of waste treatment facilities are regarded to be major challenges in the future.
