The role of biomass and biorefineries in a sustainable future

Abstract

Some o f the biggest issues facing humanity in the 21st century include energy security, global warming and resource scarcity. These issues will affect every nation and Ireland is no exception. There is much research underway to uncover technologies that will allow the world to overcome such problems, but none offer the flexibility o f biomass. Unlike other sustainable technologies, which offer a solution to one or at most two o f the above problems, biomass as demonstrated by the author, can play a part in mitigating all o f the above problems. It has been known for some time that biomass can be used in various ways as a form o f renewable energy, but with the development o f biorefineries biomass can be used to produce material as well as fuel products. In this report the author has looked at the viability and benefits o f biomass, bioenergy and biorefining in Ireland. The author has demonstrated that such technologies when implemented correctly are sustainable from an economic, environmental and societal point o f view. The author has shown in this thesis that abundant supplies o f biomass make bio re fineries a viable business opportunity in Ireland and has shown how a number o f biorefinery scenarios have the potential to be extremely profitable. The author has evaluated the profitability o f material product-based bio re fineries as well as fuel productbased configurations. The author demonstrated that value-added co-products help to make bio refineries profitable even when excise-relief is not granted on bio fuels. In this thesis the author has revealed some o f the problems that bioenergy and biorefineries have had to overcome to date and examines challenges that remain for bioenergy and biorefining, and looks at the future opportunities for bio fuels. This report concludes that biomass and biorefining has exciting business potential while offering unique opportunities to mitigate the problems o f the future.
