Our study compares the impact of two different natural dyes on cellulosic fabrics i.e., banana cotton 50:50 (Musa acuminata x Gossypium) and bamboo cotton 50:50 (Bambusa vulgaris x Gossypium). As these fabrics are natural fibres, they have a number of favourable properties when compared to artificial fibres, particularly that they are biodegradable. Selected fabrics were dyed using natural dyes derived from Rubia tinctorum L. (madder), and Punica granatum L. (pomegranate). The roots of madder and the peel of pomegranate were selected for the dyeing process. Madder was used separately for dyeing the fabrics and it was also then combined with pomegranate to compare its impact on the fabrics. The impact of the natural dye on the cellulosic fabrics was analysed by evaluating their physical strength, chemical composition, fabric surface morphology and anti-microbial activity.
我们的研究比较了两种不同的天然染料对纤维素织物的影响，即香蕉棉50:50 （Musa acuminata x Gossypium）和竹棉50:50 （Bambusa vulgaris x Gossypium）。由于这些织物是天然纤维，与人造纤维相比，它们具有许多有利的特性，特别是它们是可生物降解的。选用从茜草和石榴中提取的天然染料对织物进行染色。选用茜草根和石榴皮进行染色。将茜草单独用于织物染色，然后将其与石榴混合，比较其对织物的影响。通过对天然染料的物理强度、化学成分、织物表面形态和抗菌活性的评价，分析了天然染料对纤维素织物的影响。

Bamboo has emerged as a significant resource across various industries due to its rapid growth rate, strength and sustainability. Despite the many challenges for bamboo and its products, innovative technologies are trying to find a solution and to prepare a greener future. This paper provides a comprehensive patent-based review in four major sectors. A patent landscape analysis on bamboo was conducted using Patentscope (World Intellectual Property Organization database), Scopus Patents, Google Patents, and Lens (a public patent knowledge database). 818 patent records were retrieved from 1898 to 2024 and are discussed sector-wise. Notable patents that exemplify the latest technological strides are highlighted in each area. In the food sector, innovations such as vacuum packaging, natural preservatives and advanced processing methods have improved the shelf life and nutritional integrity of bamboo shoots. In the commercial sector, advances in bamboo fibre extraction and processing have led to higher quality and more sustainable textile products, while innovations in pulping and bleaching processes have reduced the environmental impact of bamboo paper production. In the construction sector, technologies such as laminated bamboo and bamboo composite materials have significantly improved the structural integrity of bamboo, allowing it to be used in load-bearing applications. In the environmental sector, large-scale planting techniques and optimized bamboo plantations have enhanced bamboo’s role in erosion control, land rehabilitation and carbon sequestration. Finally, we demonstrate how bamboo is aligned in achieving Sustainable Development Goals 1–17.

This study presents a comparative analysis of the physical and mechanical properties of Guadua angustifolia Kunth, a bamboo species with significant potential as a sustainable construction material. The research focuses on specimens harvested from Villavicencio in Colombia, a region characterized by high rainfall and low altitude and compares the results with data from five other geographical locations in Colombia. Eight mature culms were subjected to 193 mechanical tests, including parallel and perpendicular compression, shear, tension and bending, following the NTC 5525 standard. The study examined the lower, middle and upper sections of the culms to provide a nuanced understanding of the material's properties. Significant variations occurred in mechanical properties across different culm sections and geographical locations. Notably, the shear strength of Guadua from Villavicencio showed superior performance in the upper section, while the lower and middle sections exhibited moderate behaviour. The study also found correlations between geographical factors (altitude, temperature and precipitation) and mechanical properties, although these relationships require further investigation. This research contributes valuable data to the growing body of knowledge on G. angustifolia, highlighting its potential as a sustainable construction material. The findings underscore the importance of considering culm section and geographical origin when selecting Guadua for structural applications. Furthermore, this study lays the groundwork for future research into standardization of testing methodologies, long-term performance studies and optimization of cultivation practices.

Bamboo forests present a novel nature-based strategy to remove atmospheric carbon dioxide thanks to their extraordinary carbon sequestration capacity. In particular, Moso bamboo (Phyllostachys edulis) sequesters more than 40 tonnes of carbon dioxide per hectare annually. However, these forests have encountered challenges in some areas due to decentralized management and industry downturns. An innovative green financing model incorporating village cooperatives could address the critical problems facing the management of bamboo forests while contributing to the mitigation of the climate crisis. Meanwhile, the model will significantly benefit the less-developed communities in many parts of the world by increasing farmers’ incomes, enhancing livelihood, and boosting local economies.

This study investigated the physicochemical properties and antioxidant activity of Bambusa tulda tea. The tea exhibited low moisture and ash content, indicative of good drying quality. Its acidic pH was attributed to the presence of organic acids. Phytochemical analysis confirmed the presence of carbohydrates, reducing sugars, triterpenoids and cardiac glycosides. The dry extract contained higher levels of phenolics and flavonoids compared to the infusion, resulting in stronger antioxidant activity, as demonstrated by a lower IC50 value of 3.794 in the DPPH radical scavenging assay. Furthermore, silica (SiO₂) was extracted from the tea leaves and characterized using X-ray diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FTIR). These analyses revealed an amorphous structure and spherical morphology. Field Emission Scanning Electron Microscopy (FE-SEM) and Energy Dispersive Spectroscopy (EDS) analyses corroborated the spherical morphology and elemental composition of the SiO₂. The extracted SiO₂ effectively degraded methylene blue and Congo red dyes under sunlight, highlighting the potential of B. tulda tea as a sustainable source of SiO₂ for environmental remediation.

This paper examines the implications of fibre angle and its volume fraction (Vf) on the engineering constants of composite lamina reinforced with bamboo fibres (BFs). A polylactic acid (PLA) matrix reinforced with BFs was used to assess the engineering performance constants. The response of bamboo-PLA (BF-PLA) green composite lamina for different was also included in this study. Using the mechanics of composite lamina, the engineering constants of the lamina were varied for fibre orientation angles ranging from 0° to 90° and for ranging from 0.1 to 0.5 in increments of 0.1 (10 %). Additionally, for fibre orientation of 0° and between 0 % (full matrix) and 100 % (full fibres), the investigation provided a range in the lamina's longitudinal tensile strength in increments of 0.01 (1 %). To learn more about the BF-PLA lamina and whether it was feasible to proceed with an experimental investigation, the results were plotted for a comparative analysis. We demonstrated that the bamboo and orientation significantly affect the lamina's longitudinal tensile strength in addition to its engineering constants. We found that there was a critical fibre volume percentage of 8.2 % and a minimal fibre volume fraction of 7.3 %. We discuss the BF-PLA lamina and the applicability in designing facesheets for sandwich composite construction. Considering the outcomes of the macromechanical and micromechanical analysis of lamina, we conclude that the BF-PLA composite has the potential to act as biodegradable facesheets for environmentally friendly sandwich structures. This needs to be further explored by experimental and finite element studies.

Bamboo, a versatile and ecologically significant plant, has garnered substantial research attention in recent years. India is, home to 137 bamboo species across 31 genera that are widely distributed in natural forest and the country is a major contributor to global bamboo diversity. Bamboo rhizomes are classified into three types: sympodial, monopodial, and amphipodial, each with distinct growth patterns. The rhizosphere surrounding these rhizomes harbours a diverse community of fungi and bacteria that, play a vital role in nutrient uptake and plant health. Bamboo rhizomes also act as essential carbon sinks, contributing to climate change mitigation. Additionally, they possess phytoremediation potential, capable of absorbing heavy metals from contaminated soils. The economic importance of bamboo rhizomes extends to various applications, including construction materials, food, and medicinal uses. This review provides a comprehensive overview of the current understanding of bamboo rhizomes, highlighting their crucial roles in nutrient storage, water retention, and rapid growth. We emphasize the importance of further research into the conservation and sustainable use of bamboo rhizomes, as they hold a key role in unlocking the full potential of this remarkable plant. Additionally, the review lays a solid foundation for future studies and underscores the importance of recognizing and protecting the untapped potential of bamboo rhizomes.

<div><div>Soil phosphorus loss frequently occurs in subtropical regions, leading to extremely low phosphorus levels in forest soils. This deficiency adversely affects soil fertility and hampers normal plant growth. Nitrogen fertilization can enhance phosphorus uptake under certain conditions. However, further research is needed to determine whether N fertilization under low-phosphorus conditions can improve P use efficiency, and to identify the most effective N form to achieve this purpose. This study explored the relationship between soil nutrient dynamics and seedling physiology, evaluating the effects of various nitrogen fertilizers on the growth of <em>Phyllostachys edulis</em> seedlings under low phosphorus conditions. A two-year pot experiment was conducted using four different forms of nitrogen (NO<sub>3</sub><sup>-</sup>-N, NH<sub>4</sub><sup>+</sup>-N, NO<sub>3</sub><sup>-</sup>-N + NH<sub>4</sub><sup>+</sup>-N, and organic-N) under two phosphorus treatment levels (deficient: 5.0 mg kg⁻¹ and sufficient: 20.0 mg kg⁻¹). Low phosphorus levels altered the nutrient environment of substrates and inhibited bamboo seedling growth, while increasing phosphorus distribution in the plant. Low phosphorus stress inhibited growth and altered amino acid composition. However, seedlings adapted through adjustments to the root-to-shoot ratio, modifications to root morphology, and coordination of the transport and distribution of nitrogen and phosphorus among roots, stems and leaves. This enhanced leaf electron transfer efficiency and redistributed nutrient resources. Furthermore, NH<sub>4</sub><sup>+</sup>-N fertilizer under low phosphorus conditions increased the root-to-shoot ratio, enhanced phosphorus and metal ion uptake by roots, improved nitrogen distribution and alleviated the inhibitory effects of low phosphorus stress. Org-N fertilizer demonstrated a distinct effect under low phosphorus conditions, particularly in enhancing nitrogen retention and improving root development. The use of Org-N resulted in increased amino acid content in bamboo leaves, promoting better photosynthetic efficiency compared to inorganic nitrogen treatments. However, its effects on phosphorus use efficiency were less pronounced than those observed with NH<sub>4</sub>⁺-N. Conversely, a combined NO<sub>3</sub><sup>-</sup>-N and NH<sub>4</sub><sup>+</sup>-N fertilizer under sufficient phosphorus conditions improved photosynthetic capacity, nitrogen transport and metabolic efficiency, resulting in significantly higher total biomass. Therefore, nitrogen fertilizer forms should be carefully considered in bamboo seedling cultivation. A single ammonium nitrogen fertilizer is more suitable for bamboo seedlings in soils with severely low phosphorus, whereas a mixed inorganic nitrogen fertilizer is better for soils with adequate phosphorus. This study uniquely demonstrates how specific nitrogen forms can enhance phosphorus utilization efficiency in Moso bamboo seedlings under low pho

The boards were prepared at four different specific pressures, namely 21.0, 24.5, 28.0 and 31.5 kg/cm2 and hot pressed. The prepared boards were then tested for their physical and mechanical properties as per Indian standard 1708. Bamboo scrimbers were prepared and tested to evaluate their potential as a sustainable alternative to traditional wood for construction. The mechanical properties of the different bamboo scrimbers were compared with conventional wood species. The results showed that boards prepared at higher pressures (24.5, 28.0 and 31.5 kg/cm²) exhibited comparable or superior properties to commonly used woods such as teak (Tectona grandis L.f.), sal (Shorea robusta C.F.Gaertn.) and khair (Senegalia catechu (L.f.) P.J.H.Hurter & Mabb.), in terms of modulus of rupture, modulus of elasticity, compression strength, hardness and screw withdrawal capacity. Boards prepared at 31.5 kg/cm² were suitable for heavy structural applications, while boards prepared at 24.5 and 28.0 kg/cm² were suitable for moderate load-bearing applications. Boards prepared at 21.0 kg/cm² were ideal for non-load-bearing uses. The high density, strength, hardness and screw withdrawal capacity of bamboo scrimbers make them suitable for a wide range of construction applications, including flooring, furniture and cladding. These findings demonstrate that bamboo scrimbers are a viable sustainable alternative to traditional wood, potentially reducing the reliance on limited natural wood resources.

Browning is a limiting factor for the successful propagation of several, mainly woody, plant species through tissue culture. Bamboos are not exempt from this constraint, which has been described as particularly critical for the micropropagation of several Bambusa species, such as B. lako. To understand the browning process in this species, we investigated whether the browning of in vitro nodal explants was linked to the accumulation of phenolic compounds, polyphenol oxidase activity, and oxidative stress as indicated by the presence of malondialdehyde. A four-point Browning Gradient Index was developed to evaluate these biochemical parameters. We observed an increase in the concentration of total phenolics, polyphenol oxidase activity, and malondialdehyde levels between green and fully brown grades. Histological analysis revealed a greater accumulation of protein in the green shoots compared to brown tissues. Polyphenols and peroxidase were localized in the vascular bundles in all browning grades.
