The objectives of this research are to develop a novel assessment methodology for evaluation of the risks and potential pay-offs of new technologies that avoid pollutant production; and demonstrate the methodology via case study of solid waste gasification technology. A methodology for simultaneous characterization of both variability and uncertainty based upon previous work in emissions estimation, exposure assessment, and risk assessment is developed. To represent uncertainties in any process technology, a probabilistic modeling is applied to the case of solid waste gasification.

This can be enabled through advances in economic geography explaining the role of ongoing changes in the Information, Communication and Technology (ICT) sector on the way the work is organised and carried out. Although in this research field ICT is commonly regarded as facilitator of work from anywhere, attention of researchers is predominantly focused on implementation and analysis of telework strategies. Our paper is an attempt to provide a better understanding of the impacts of work from anywhere on cities, through analysis of a spatial distribution of home based workers in Sydney and Melbourne metropolitan areas. The research explores the correlation between home based workforce and socio-economic status of local government areas using 2011 Australian Bureau of Statistics (ABS) census data. It also considers the role of distance from major cities as factor influencing home based work in regional areas. Results highlight a significant positive correlation between socio-economic qualities and the homebased workforce within the two major cities and their urban-rural fringes. In regional parts of New South Wales and Victoria the distribution of home-based workers is not related to the socio-economic qualities of areas but is strongly correlated with distance from major cities. This spatial arrangement provides an opportunity to delineate and map the distribution of lifestyle home based workers. These findings contribute to a better understanding of locational preferences of home based workforce and implication of these on city and regional planning and development.

Key concepts from industrial ecology have been adopted as basis for the approaches in configuring the waste management framework for gold mining. The relevance of industrial symbiosis and systems thinking in the framework for gold mining are emphasized, specifically on the objective of addressing the three pillars of sustainable development – people, planet and prosperity. The application of the key concepts of industrial symbiosis and systems thinking in forming the science for SWM in gold mining and developing the SWM framework are envisioned to provide sustainability in reducing wastes and mitigating environmental impacts.

Japan and China lead in these initiatives, having pursued extensively circular economy in the manufacturing, energy, and agriculture sectors. The CE in the forestry sector has just been initiated in China. Germany and Finland demonstrate circular economy insights for forestry that are highly relevant to the forestry sector of the Philippines’ Timber Corridor, while the Philippines is transitioning toward circular economy. The Caraga Region is currently crafting a roadmap where research is at the core to develop a database for the science-based information necessary to advancing circular economy for a sustainable forestry sector. Integration of circular practices into the forestry sector and the innovative reuse of wood waste are the key actions for transitioning toward a forestry-based circular economy in Caraga Region, Philippines.
