In situ Autohydrolysis for the Glucose Production from Sago Pith Waste with DIC Technology

Abstract

Instant controlled pressure drop (DIC) technology was utilized in the production of glucose from sago pith waste (SPW). In situ autohydrolysis was conducted in a DIC reactor to obtain the maximum glucose production. The influence of pressure, acid concentration, and treatment time on the glucose yield from SPW subjected to DIC-assisted in situ autohydrolysis was determined, and the experimental conditions were optimized using the response surface method. The results showed that the linear term of acid concentration and the quadratic terms of pressure and time had a significant effect on the glucose yield. The optimized experimental conditions for maximum glucose production (48.21%) from SPW subjected to DIC-assisted autohydrolysis were a pressure of 0.1 MPa, acid concentration of 0.1 M, and time of 4 min. The findings demonstrated that DIC technology has the potential to be utilized for the commercial production of glucose from SPW.

Recyclable, sustainable, and stronger than portland cement: a composite from unseparated biomass and fossil fuel waste

“…1 Current leading technologies for valorising biomass are energy or solvent intensive -pyrolysis, steam explosion, extraction and filtration or pressing, etc. [2][3][4][5][6][7][8][9][10] Herein is reported a method to prepare a composite using unseparated biomass as a starting material. The other comonomer is sulfur, a waste product of fossil fuel refining.…”
