By treating organic wastes as a resource, and applying a different method of waste management, organic wastes could contribute
significantly to global energy needs.
The ethanol distillation process waste product, stillage, is a soup-like waste stream that
contains substantial organic content. By digesting this material
three resources are recovered – biogas (80 per cent methane),
biosolids (high in nutrients equivalent to high grade fertiliser) and recyclable water.
Current waste treatment in ethanol
production focuses on drying the stillage waste and using the resultant material as mulch to be spread over crops. This is an
energy intensive, low-benefit, process that increases production cost. If a waste treatment process could convert the waste...

The objective of this study is to develop spatially-explicit choice model and investigate its validity and applicability in CA studies.
This objective is achieved by applying locally-regressed geographically weighted regression (GWR) and GIS to survey data on
hypothetical dogrun facilities (off-leash dog area) in urban recreational parks in Tokyo, Japan. Our results show that
spatially-explicit conditional logit model developed in this study outperforms traditional model in terms of data fit and prediction
accuracy. Our results also show that marginal willingness-to-pay for various attributes of dogrun facilities has significant spatial
variation. Analytical procedure developed in this study can reveal spatially-varying individual preferences on attributes...

Nationwide mail surveys implemented in November 2004 report New Zealand residents‟ willingness to pay for improvement in
ecosystem services and support for organic farming on arable land. The surveys were split into two subsets: Canterbury, which is
the region with most arable farming in the nation, and the other New Zealand regions. Analysis of the data reveals that Canterbury
