Sustainability Indicators Review of Hemp Shiv as Alternative Materials for the Construction Industry in Thailand
Keywords:
Sustainable Construction, Eco-materials, Upcycling, Green Economy, Land Use Change, CO2 OffsetAbstract
Currently hemp is promoted worldwide for its many uses, however, in Thailand it is still limited and in the trial period. All parts of hemp can be utilized; the flowers, leaves and roots are used for medicinal and treatment purposes, food supplement, vitamins, etc. The stalk fibers are used in the fabric industry and are being researched for applications in the energy and other high-tech industries. The leftover stalk or hemp shiv is used as wood replacement or applied in the construction industry in various forms in countries where hemp is grown and used in the industrial scale but in Thailand they are still left as unmanaged or invaluable waste. Hemp shiv possesses characteristics of desirable construction materials in hempcrete and hemp concrete blocks replacing coarse aggregates. There are many researches on its abilities as wall materials showing that they have the potential of being used as non-load baring walls. However, the amount of hemp shiv required to sustain production will require land use change from edible to non-edible economic crop. This is very risky and the result may increase the vulnerability to the effects of Climate Change. Thus, the objective of this study is to assess the sustainability of hemp shiv as alternative materials for the construction industry in Thailand based on sustainability indicators on environment, social and economic impacts of industrial hemp and CO2 offset for using hemp as coarse aggregates and also to explore the economic feasibility and increased potential for upcycling hemp waste as construction products.
