Extraction of Bamboo Sap by High-Efficiency Hot Pressing: A Method for High Value and Sustainable Use of the Bamboo Material.

To develop an effective and eco-friendly method for extracting bamboo sap can effectively improve the utilization of bamboo resources and promote the sustainable development of the bamboo industry. In this work, fresh bamboo strips were directly placed into a hot press for hot pressing (HP), yielding both pure bamboo sap and flattened, dense bamboo strips. The physicochemical properties of bamboo sap and bamboo strips were systematically investigated.
