“…In comparison to the conventional ''dry- 52 tomb" landfills, the bioreactor landfills have proven to have many 53 advantages and benefits, which include rapid stabilization of waste, 54 improvement of landfill gas production rate and total yield, signif- 55 icant gain in landfill space and considerable reduction in time and 56 cost of post-closure monitoring and maintenance e.g. [53,6,71]. To 57 optimize the design and operation of the bioreactor landfill, it is 58 essential to be able to accurately assess and predict the landfill 59 gas generation and settlements in both short and long-terms [20].…”

“…Therefore, the key step to develop any 67 predictive tool for estimating the landfill settlement is to under- 68 stand the dominant biochemical reactions occurring during the 69 waste decomposition process and thereby create mathematical 70 models to describe those reactions. So far, the former aspect has 71 been widely investigated through both laboratory and field exper- 72 iments (e.g. [52,1,57,30,21,4,2,37]).…”

“…and in summer, respectively. The higher EC value could be explained by biodegradation of macromolecular organics in the leachate to produce organic acids which increased conductivity (Sivula et al, 2012), while the lower one might be attributed to the rainy day when leachate was diluted (Yuen et al, 2001). However, the EC values in summer, was 83.3% lower than that in winter on average, possibly due to the fact that the proportion of kitchen garbage in winter was relatively higher, introducing more salinity into the leachate.…”

“…However, given the extremely dry climate, the very low moisture of domestic waste, and the low content of kitchen waste, it is possible to build a relatively simplified landfill with a liner system, landfill gas venting system, and capping system among some neighboring villages or towns. Notably, leachate recirculation can maintain an optimum moisture condition of at least 31% volumetric moisture content (Yuen et al, 2001). Transfer stations in which waste can be sorted and be transferred to neighboring landfills need to be established in every village.…”

In the rural area of the Tibetan Plateau (RATP), the characteristics of domestic waste, people's environmental awareness, people's willingness to pay and their influence factors were firstly studied by questionnaires, field samplings and laboratory tests. The results showed that, in the RATP, the generation of domestic waste was 85 g•d-1 per capita and it was mainly composed of plastics, inert waste, kitchen waste, glass and paper. The waste bulk density, moisture content, ash, combustible and low calorific value were 65 kg•m-3, 19.25%, 44.90%, 35.85% and 10,520 kJ•kg-1 respectively. These characteristics are influenced by income sources and geographical position to some extent. Classified collection should be promoted widely on the household and the village basis. Compost, fermentation, landfill, bioreactor landfill and semi-aerobic landfill have been approved as effective techniques to treat domestic waste, except incineration. The distance of 50-800 m between each collection facility and the disposal fee of around $0.8 per month per household are suggested. For suburbs or large population villages, it's better to treat domestic waste by the centralized way. But for the remote rural areas, a decentralized way is proposed. Significantly, the educational and economic influence should be considered into an effective domestic waste management program. Implications:The current situatio n of the environment in the rural areas of the Tibetan Plateau (RATP) was surveyed. There, the generation of organics and moisture of domestic waste were low but ash, recyclables, and combustibles were high. People's knowledge of domestic waste was absent but their participation in management was strong. Based on the current situation, compost, fermentation, and landfill were effective but incineration was inappropriate. Also, a localized mini landfill for a cluster of villages and or settlements was the best method there. IntroductionThe Tibetan Plateau is a large tectonic geomorphological region in central Asia with an average altitude of 4,000 m and a total area of 2,250,000 km 2 that contains a population of 10, 214,200 (Chen and Shen, 2000). Due to its high altitude, low atmospheric pressure, low oxygen content, and low temperature, the environment is very sensitive and fragile. Moreover, it is lacking in preventative and self-renewal capability (Jiang et al., 2009). The Tibetan Plateau is also the source of the Yellow, Yangtze, and Lantsang rivers, and its water reserves comprise one-third of the total reserves of China. Therefore, the environmental health of the Tibetan Plateau is of significant concern to China and other Southeast Asian nations.Economic development and changes in lifestyles in the Tibetan Plateau have resulted in increasing consumption of packaged and processed goods, including food and other items, in recent decades, especially since opening of the Qinghai-Tibet railway. Dan and Han (2012) reported that the amount of municipal solid waste (MSW) in Lhasa increased rapidly to 600 t d −1 in 2010. The MSW in thi...
