Bamboo for Carbon Neutral Development
Published in Yan Xiao, Engineered Bamboo Structures, 2022
Bamboo buildings and bridges constructed directly from bamboo components are the most traditional forms of bamboo construction. In the 1950s, there was some research activity in China on round bamboo structures for the purpose of saving steel and timber.[17,18] However, systematic development and industrialized applications in construction do not seem to have followed. Most practices in construction using round bamboo in China are traditional in manner, represented by the so-called “Ganlan-style” bamboo buildings in the Southwest region of China. In recent years, buildings made of round bamboo are gradually returning to China, led primarily by architects, with some interesting buildings being constructed.[19,20]
Innovations in round bamboo construction
Published in Y. Xiao, Z. Li, K.W. Liu, Modern Engineered Bamboo Structures, 2019
Round bamboo construction has a long history in countries with abundant bamboo resources, such as China, India, and South America. Bamboo, as an environmentally friendly construction material, has advantages such as fast-growing, high strength, low density, low production cost, ease of manufacturing etc., The round bamboo building is graceful, flexible and diverse, which is not only a place for people to rest, but also a unique landscape line of the cultural tourism scenic spot, with beautiful appreciation value and the value of garden culture and art. However, the development of round bamboo construction is yet to be well developed to meet modern construction requirements, due to (1) mildew and insects, (2) difficulty in connection and support, (3) insufficient design innovations. Therefore, this paper discusses the methods of trying to solve the above problems in the round bamboo construction industry and some projects are introduced.

It is clear that there is scope for the application of engineered bamboo in the construction industry, and the carbon reduction potential of bamboo buildings throughout their life cycle has become the focus of much attention. Yu, Tan, and Ruan (2011) investigated and analysed the energy consumption and carbon emissions of bamboo-structure residential buildings in China. Zhang et al. (2021) analysed the carbon emissions of a new steel – bamboo composite frame structure for a residential house. Xu, Xu, et al. (2022) quantified carbon storage and emissions in six phases of the life cycle of bamboo construction materials and analysed the potential for carbon reduction. The findings of these studies point to the fact that the environmental impact of bamboo construction materials over their life cycle is easier to control than that of other construction materials (Xu, Zhu, et al., 2022). Since data on the carbon content of bamboo materials is still limited, the most relevant research is based on the available literature and published information from manufacturers. In addition, the production and construction technologies of bamboo buildings are still evolving and there are presently very few systematic life-cycle studies.

The economic benefits of bamboo housing arises, not only from the low cost of bamboo as a material but also from the fact that it is a means of income for people who work in the bamboo industry, be it construction of houses or making engineered bamboo construction materials. These jobs include conventional agricultural jobs common in developing regions as well as higher-skilled jobs required to process the bamboo raw material into value-added products, such as furniture, housing, composites, etc. (Dagilis 1999). However, the benefits have not always reached the very poor; many researchers did not take into account that the users in their studies were poor people living in rural areas of tropical countries where bamboo grows, where steel bars for concrete are scarce or unavailable (Hidalgo-López 2003). In many places, like in Philippines where demand exceeds the supply, over-harvesting and premature harvesting are major problems (Ramirez 1995), and this will lead to degeneration of the bamboo forest.
