Seminar Details
Energy efficient building has created increased prevalence of engineered timber systems use in modern domestic construction, yet basic principles of moisture transfer are being ignored reducing the life of these buildings and lessons of the built-in problems are being ignored ( Housing Defects Act 1984). How long would it be before these materials find their way into the waste disposal cycle and force additional rounds of expenditure? Considering the life of timber-frame building of being approximately 50 years, by the mid 21st century arrival of large quantities of timber waste is expected.
How the European Waste Directive are affecting waste processing, creating a future problem for processed/engineered timber components.
Fallacies of some of the Initiatives dealing with processed/engineered timber waste. Engineered timbers contain chemicals that when heated would generate toxic compounds, but it is not only the engineered timber.
We have used ?Treated timber? in construction for some considerable time, early preservatives like creosote and later chromated copper arsenate (Tanalith) as well as other such as ?alkali metal cyanides? contain not only cyanides but also some heavy metals. All of these can find their way into the environment not only through smoke but also through the ash disposal.
Problems with processing of these timbers into Biomass and potential ways of dealing with this problem.
Composting of these timbers and leaching of the chemicals into the environment.
The paper will address the issues and hopefully drive the efforts in the right direction.
