“…Among the various substances and their mixtures that have been suggested, investigated, and commercialized, the use of low-cost soluble salts, such as boronbased salts specifically disodium octaborate tetrahydrate (DOT), boric acid, and borax, is interesting alternatives for the treatment of bamboo and wood [24,28,38,39]. Boron compounds are some of the most effective and versatile preservatives solutions used nowadays since they combine the broad-spectrum efficacy, low mammalian toxicity, odorless, colorless, and fire-retardant properties [40][41][42][43]. The preservation method with boron compounds can be even a way to improve the quality of bamboo, increasing the tensile strength in comparison with bamboo without preservatives [44,45].…”

The chemical treatments applied to some lignocellulosic resources commonly used as building materials can influence their mechanical performance during service, and hence, this effect should be studied for structural safety reasons. In this piece of work, prismatic samples of Dendrocalamus asper bamboo were treated in a vacuum/pressure process with disodium octaborate tetrahydrate (DOT) solutions and the corresponding mechanical performance was compared with non-treated and water-treated samples. Full penetration of boron was achieved, with DOT retentions of 14.79 kg m −3 and 21.79 kg m −3 for 5% and 8% (wt/wt%) solutions, respectively. Dynamic modulus of elasticity (MOE), static MOE, and compressive modulus of elasticity of the material, with values between 23.3-24.0, 15.9-16.2, and 26.2-27.2 GPa, respectively, were statistically equivalent for all the analyzed treatment conditions. However, a significant influence of the treatment could be observed on the specific compressive strength of bamboo, showing an increase of 35.3% for the 5% solution and 30.6% for the 8% solution. Although without statistical difference among the treatments, similar behavior was observed on the specific modulus of rupture (MOR) under flexural loading, with an increase of up to 10.1% in relation to the reference for the treated samples. The results achieved in the present study from nondestructive excitation pulse, three-point bending, and axial compression tests demonstrated that mechanical behavior of bamboo was preserved or even enhanced by the proposed treatments based on disodium octaborate tetrahydrate.

“…Bamboo is a grass growing in most regions of the world, including tropical and subtropical regions as well as temperate climates 36 , and used for a large variety of applications including food, construction, textiles, paper, charcoal, etc 37 . What makes bamboo particularly interesting is its fast-growing rate and high mechanical properties for a low weight.…”

Mycelium-bound composites (MBCs) are materials obtained by growing fungi on a ligno-cellulosic substrate which have various applications in packaging, furniture, and construction industries. MBCs are particularly interesting as they are sustainable materials that can integrate into a circular economy model. Indeed, they can be subsequently grown, used, degraded, and re-grown. Integrating in a meaningful biocycle for our society therefore demands that MBCs fulfil antagonistic qualities which are to be at the same time durable and biodegradable. In this study, we conduct experiments using MBCs made from the fungus species Pleurotus ostreatus grown on bamboo microfibers substrate. By measuring the variations of the mechanical properties with time, we provide an experimental demonstration of a biocycle for such composites for in-door applications. We found that the biocycle can be as short as 5 months and that the use of sustainable coatings is critical to increase the durability of the composites while maintaining biodegradability. Although there are many scenarios of biocycles possible, this study shows a tangible proof-of-concept example and paves the way for optimization of the duration of each phase in the biocycle depending on the intended application and resource availability.

“…Using their skills and capabilities, artisans can prepare various simple items using bamboos, which can attract high value in rural and urban markets. 10 In addition to building material, it can be used by the local community for making fences, ladders, handicraft items, utensils, etc. When planted around ponds as watershed, bamboo can help to decrease the evaporation of water from ponds, thus help in water conservation.…”

Bamboo is a grass found easily on almost all continents with special ability to grow on wasteland as well. The resources of bamboo are wide and available globally with China and India contributing to the maximum world bamboo forest. Due to its special unique features, there is a great demand for bamboo and its product in the market. The tensile strength of bamboo (28,000 pounds per square inch), is much higher than steel (23,000 pounds per square inch). The utilization potential of bamboo is enormous. The present paper discusses an overview of special properties of bamboo and its utilization potential. Opportunities and threats to the market of bamboo are also discussed.
