IVC 2024 Parametric Bamboo for Post Disaster Reconstruction3 Introduction to Bamboo Dr.-Ing. Andry Widyowijatnoko, S.T., M.T., IAI School of Architecture, Planning and Policy Development Institut Teknologi Bandung Indonesia Introduction to Bamboo - Andry Widyowijatnoko contents: background why bamboo definition characteristics of bamboo Introduction to Bamboo - Andry Widyowijatnoko background Buildings and construction together account for 36% of global final energy use and 39% of energy-related carbon dioxide (CO2) emissions when upstream power generation is included. This data covers buildings and construction, including the manufacturing of materials and products for building construction. (Global Status Report 2017, United Nations Environment Programme) Introduction to Bamboo - Andry Widyowijatnoko Architect and Ecology Which one do you want to use steel as your building material? bamboo timber concrete Introduction to Bamboo - Andry Widyowijatnoko Sustainability: STEEL TIMBER vs & CONCRETE renewable resource + + lifetime, durable carbon sink + O2 producer + - non-renewable resource low energy consumption + - CO2 emission - O2 consumer deforestation - - high energy consumption Introduction to Bamboo - Andry Widyowijatnoko Sustainability: STEEL BAMBOO vs & CONCRETE renewable resource + + lifetime, durable carbon sink + O2 producer + - non-renewable resource low energy consumption + - CO2 emission - O2 consumer deforestation - - high energy consumption Introduction to Bamboo - Andry Widyowijatnoko what is bamboo? Bamboo is not a tree but a giant grass, family: Poaceae subfamily: Bambusoideae 1,439 species in the world 161 species in Indonesia (126 native species) 62 species in the Philippines (21 native species)* *https://www.bioversityinternational.org/fileadmin/bioversity/publications/Web_v ersion/572/ch30.htm Introduction to Bamboo - Andry Widyowijatnoko what is bamboo? 2 general types: Sympodial (clumpers) Monopodial (runners) Introduction to Bamboo - Andry Widyowijatnoko sympodial (clumpers) in tropical climates cannot withstand freezing temperature, except Fargesia spp. (-25oF) reproduction with pachymorph rhizome system non-invasive Fargesia robusta Wolong Introduction to Bamboo - Andry Widyowijatnoko runners (monopodial) in temperate climates o o temperatures between -10 and +15 F reproduction with leptomorph rhizome system potentially invasive Moso bamboo (Phyllostachys edulis) most genera Phyllostachys and Pleioblastus Introduction to Bamboo - Andry Widyowijatnoko why bamboo renewable resource bamboo grows in a variety of conditions no fertilizer, pesticides, or herbicides needed very little waste versatility economic development Introduction to Bamboo - Andry Widyowijatnoko bamboo for land conservation research in China: the foliage keep the humidity and have lowest erosion index compare with 14 other monoculture forest research in Kyoto University: the root system of monopodial bamboo is very effective to prevent landslide Introduction to Bamboo - Andry Widyowijatnoko The presence of bamboo, with its extensive rhizome and root network and dense canopy, helps to reduce soil erosion, which reduces run- off and hence improves retention of nutrients and regulation of water flow in rivers and lakes (Li and Kobayashi, 2004; Song et al., 2011; Lobovikov et al., 2012). Yuen, J. Q., Fung, T., & Ziegler, A. D. (2017). Carbon stocks in bamboo ecosystems worldwide: Estimates and uncertainties. Forest Ecology and Management, 393, 113-138. Dendrocalamus (c) Google Images asper, Brazil Introduction to Bamboo - Andry Widyowijatnoko bamboo for watershed research in China: water absorption bamboo forest to the soil up to 240% higher than Pinus massoniana bamboo has a high WUE (water use efficiency) but grows fast (Gielis, 2000) the greening project with bamboo in ex- brick mining in India can raise ground water level 6,3 meter in 4 years Introduction to Bamboo - Andry Widyowijatnoko bamboo as CO2 sequester bamboo: 62 tons/Ha/year other forest: 15 tons/Ha/year bamboo generates up to 35% more oxygen then equivalent stand of trees Introduction to Bamboo - Andry Widyowijatnoko plants absorb CO2 from air to grow and decompose to release CO2 (Illustration by Jack Cook © Woods Hole Oceanographic Institution) https://www.whoi.edu/know-your- ocean/ocean-topics/how-the-ocean- works/cycles/carbon-cycle/ Introduction to Bamboo - Andry Widyowijatnoko plants absorb CO2 avoid decay, from air to grow store as building material or and decompose to use as charcoal for planting release CO2 media (carbon sink) The conversion factor is 44/12, which means that for every 12 grams of carbon, 44 grams of CO2 are sequestered Introduction to Bamboo - Andry Widyowijatnoko carbon footprint This study compares the carbon footprint of products from bamboo materials such as strand woven bamboo, plybamboo, flattened bamboo, with non-bamboo products. Products made from bamboo produce a very low carbon footprint than non- bamboo products. If calculated by carbon sequestration, the carbon footprint of its production does not exceed that of carbon production. Van der Lugt, P., J.G. Vogtländer, J.H. van der Vegte, J.C. Brezet, 2012. Life Cycle Assessment and Carbon Sequestration; the Environmental Impact of Industrial Bamboo Products. Proceedings 9th World Bamboo Congress, Antwerp, Belgium. Introduction to Bamboo - Andry Widyowijatnoko carbon sequestration Compared to Chinese fir, in 60 years bamboo still absorbs more carbon along with production. if the Moso bamboo forest is unmanaged and not harvested for the production of durable products, the forest quickly comes to an equilibrium as the mature stems become old and decay, blocking space for new young culms.

Proceedings 9th World Bamboo Congress, Antwerp, Belgium. Introduction to Bamboo - Andry Widyowijatnoko In the environment, bamboo development reduces the pollutions. It reduces up to 35% carbon dioxide and delivers more oxygen than other hardwood trees to the environment and it reduces the use of timber consumption. Syeda, A., Shrujal, B., & Kumar, J. (2014). A case study on bamboo as green building material. International Journal of Engineering and Advanced Technology, 4, 78-82. Introduction to Bamboo - Andry Widyowijatnoko bamboo as biomass producer bamboo produce a very high biomass 7 times higher than other tree 5th of the world’s fastest biomass producing genus grows 10-30% per year, compare with 2-5% per year for other tree produce 50-100 tons biomass per Ha.; divided in 60-70% poles, 10-15% branches, 15-20% leaves Introduction to Bamboo - Andry Widyowijatnoko growing anatomy Fibers of 1 & 12 year old culm of P. viridi-glaucescens Introduction to Bamboo - Andry Widyowijatnoko In fact, the Guinness Book of World Records states that there are “certain” species of bamboo that can grow up to a rate of 35 inches (1 m) per day. Though it does not state the exact species that grows the quickest, it is more than likely a member of the Bambusa and Phyllostachys genera. Introduction to Bamboo - Andry Widyowijatnoko bamboo as fastest growing plant The world record for the fastest growing plant belongs to certain species of the 45 genera of bamboo, which have been found to grow at up to 91 cm (35 in) per day or at a rate of 0.00003 km/h (0.00002 mph).
