Development of Biomass Materials of the Byproducts of Sponge City Construction in Changde

Abstract

In order to drive the development strategy in response to innovate and promote the construction of sponge city in Changde, the green industrial chain model of new biomass material was constructed based on the byproducts of spongy city construction, such as reed and pennisetum were used as substrates. 18 invention patents were created, such as "A herbaceous plant based weatherproof stealth plate and its preparation method". The technical principles based on the series of invention patents were expounded, the innovation of core patent technology was analyzed, some works of patent technology transformation and application were presented, and the technical economic value and application prospect of core patents were discussed. The results show that the new biomass materials, such as 3D printing consumables, outdoor weatherproof materials, absorbing stealth plates and mechanical engineering materials, which are the base material for the construction of the spongy city, have a broad application prospect and great technical and economic value
