Mobility - the movements of people, things, and ideas, as well as their associated cultural meanings - has been a key factor in shaping Canadians' perceptions of and interactions with their country. Approaching the burgeoning field of environmental history in Canada through the lens of mobility reveals some of the distinctive ways in which Canadians have come to terms with the country's climate and landscape. Spanning Canada's diverse regions, throughout its history, from the closing of the age of sail to the contemporary era of just-on-time delivery, Moving Natures: Mobility and the Environment in Canadian History examines a wide range of topics, from the impact of seasonal climactic conditions on different transportation modes, to the environmental consequences of building mobility corridors and pathways, to the relationship between changing forms of mobility with tourism and other recreational activities. Contributors make use of traditional archival sources, as well as historical geographic information systems (HGIS), qualitative and quantitative analysis, and critical theory. This thought-provoking collection divides the intersection of environmental and mobility history into two approaches. The chapters in the first section deal primarily with the construction and productive use of mobility technologies and infrastructure, as well as their environmental constraints and consequences. The chapters in the second section focus on consumers' uses of those vehicles and pathways: on pleasure travel, tourism, and recreational mobility. Together, they highlight three quintessentially Canadian themes: seasonality, links between mobility and natural resource development, and urbanites' experiences of the environment through mobility.

The notion of a lifestyle system leading to zero waste is obviously appealing, and a strategy of total reuse and recycling of: waste material is often advocated. However, there is a growing realization that the recycling process itself produces waste, and the environmental and economic cost of recycling and reusing certain materials invalidates the zero waste approach as a universally viable solution. Thus, solutions must be found to deal with the part of waste that it is not practicable to recycle or reuse. The energy content of municipal waste (whether raw or classified) is about 10MJ kg-1. If the total amount of waste material in any region is around 30 million tons per year or about 1000 kg/ s, the total energy is thus 10,000MJ /s = 10,000 MW. At an electricity generation efficiency of 20%, this could provide 2000 MW plus about 6000MWof district heating. This energy source is largely biomass, which is carbon dioxide neutral, and thus does not contribute to the total atmospheric greenhouse gases. The present work includes many aspects of municipal solid waste combustion, such as the effects of moisture, particle size and ash content effects on solid particle during process rates (moisture evaporation, volatile release, and char burning rate). The COMMENT code has developed to reveal much detailed information on the combustion processes. Through experimental and numerical investigations, the combustion process of simulated MSW in bed can be better understood and the experiment results can be used to amend the mathematics model and be consulted by the application in the project. The results from modeling can show the combustion process, and make us deeply know how the heat transfers in the fuel and gas yields from fuel. At the same time, the simulation can predict the maximum temperature of waste incineration and the trend concerning combustion.
