Fast microwave-assisted co-pyrolysis of pretreated bamboo sawdust and soapstock was conducted. The pretreatment process was carried out under microwave irradiation. The effects of microwave irradiation temperature, irradiation time, and concentration of hydrochloric acid on product distribution from co-pyrolysis and the relative contents of the major components in bio-oil were investigated. A maximum bio-oil yield of 40.00 wt.% was obtained at 200 °C for 60 min with 0.5 M hydrochloric acid. As pretreatment temperature, reaction time and acid concentration increased, respectively, the relative contents of phenols, diesel fraction (C12 + aliphatics), and other oxygenates decreased. The gasoline fraction (including C5-C12 aliphatics and aromatics) ranged from 55.77% to 73.30% under various pretreatment conditions. Therefore, excessive reaction time and concentration of acid are not beneficial to upgrading bio-oil.

Bamboo powder, a novel ingredient, is gaining recognition for its potential as a dietary supplement in poultry feed. This study aimed to investigate the effects of fermented bamboo powder (FBP) on antioxidant status, gut hormone activities, intestinal digestive enzyme activities, gut morphological structure, gastrointestinal development, and the expression of nutritional transporter genes in dwarf yellow-feather broiler chickens. A total of 600 healthy 1-day-old chicks were allocated randomly into two groups, with 10 replicates per group and 30 chicks in each replicate.

In the previous study, discarded oyster farming bamboo scaffolding (BS) demonstrated the potential for application in pulping and papermaking through the soda pulping process. However, soda pulping involves high temperatures and chemical dosages. Therefore, this study develops an alternative pulping process to lower temperature and chemical demands by utilizing a high-consistency kneader (HCK), simultaneously promoting the utilization of BS in pulping and papermaking.

Lead (Pb) is a hazardous element that affects the growth and development of plants, while silicon (Si) is a beneficial element for alleviating the stress caused by heavy metals, including Pb. However, the mechanisms of Si reduce Pb accumulation in Moso bamboo remain unclear. In this study, physiological assessments and transcriptome analyses were conducted to investigate the interaction between Si and Pb.

Bamboo is widely distributed around the world as an excellent renewable resource. However, the structural and morphological changes in the bamboo samples in extracting bamboo cellulose fiber using alkaline-acidic sodium chlorite are unclear, and the potential for preparation of cellulose packaging films is yet to be explored. In this paper, the changes in micro-morphology, chemical structure, and pyrolytic behavior of moso bamboo powder during alkaline and acidic sodium chlorite pretreatment were intensively investigated.

Composites derived from plant fibers are promising reinforcing materials for engineering because of their renewable and easily available characteristics. In this study, a simple pretreatment method was developed to fabricate structurally intact bamboo cellulose scaffolds. Water-stable, flexible, impact-resistant, and high damping ratio bamboo-based rubber composites were synthesized using carboxylated styrene-butadiene latex-impregnated 3D bamboo scaffolds.
