HP RAMP

HP RAMP is a mild biomass preconditioning process designed to enhance
the anaerobic digestion of lignocellulosic biomass. This results in a

significant reduction in the process time or hydraulic retention time (HRT)
from 38 to 28 days. HP-RAMP has undergone extensive testing at a 30 kg
capacity pilot plant in HPGRDC, Bangalore, using a diverse range of

feedstocks such as rice straw, bagasse, Napier grass, mixed biomass,
mustard, and pine needles. This innovative technology holds promise in

improving the efficiency of biomass preconditioning for anaerobic digestion
applications.

HP ASAP

HPGRDC has developed an in-house technology known as HP-ASAP,

representing a single-step pretreatment process for the fractionation of
lignocellulosic biomass. This technology achieves maximal recovery (over
85%) of cellulose and hemicellulose, coupled with approximately 40%

delignification. HP-ASAP has been extensively tested at a 1-ton capacity
pilot plant in HPGRDC, Bangalore, utilizing both rice straw and sugarcane

bagasse. Key highlights include adaptability to larger biomass, reduced
energy consumption during pre-processing, decreased capital and
operating expenditure, and an overall reduction in process time by

approximately 40% (from 120 hours to 72 hours).
