Shows why plastics, in aggregate, have become a toxin to humans, wildlife, and the planet, and proposes novel solutions that involve neither traditional recycling nor giving up plastic. "Plastics!" In the 50 years since Dustin Hoffman's character in The Graduate was instructed that this was the career field of the future, we have not been able to escape this ubiquitous but poorly understood material. Author Jack Buffington argues that the plastics crisis is careening toward a tipping point from which there will be no return. There is still time, however, to do something about this crisis if we have the imagination and the will to move away from the failed policies of the past. This book is the first to propose a new model for linking our synthetic world to the natural one, rather than seeking to treat them as separate entities. The key is supply chain innovation. Buffington presents five market-based solutions based on this principle that will allow consumers to continue to use plastic, which has in many ways enabled our way of life. Alongside these proposed solutions, he also addresses the proliferation of plastic as we know it—growth that, if left unchecked, will lead to a "planetary crisis," according to the United Nations—and considers how the material itself might be adapted for a sustainable future.

These proceedings, arising from an international workshop, present research results and ideas on issues of importance to seismic risk reduction and the development of future seismic codes.

This book focuses on the mechanical properties and permeability of coal, and the gas flow in coal seams. Based on coal permeability models, it establishes different models for coal seam gas, from the linear flow model to the gas–solid coupling flow model. It also provides the theoretical basis for the exploitation and safe production of coal as well as coal seam gas resources. As such, it is a valuable reference for researchers, advanced students and practitioners working in mining engineering and coalbed methane engineering.

This work comprises papers based on some of the talks presented at the IUTAM Symposium of the same name, held in Cape Town, January 14-18, 2008. This volume treats cutting-edge issues in modelling, the behaviour of various classes of inelastic media, and associated algorithms for carrying out computational simulations. A key feature of the contributions are works directed at modelling behaviour at the meso and micro-scales, and at bridging the micro-macro scales.
