A great abundance of lignocellulosic, non-edible biomass ranging from biomass waste in the agricultural as well as forestry sector exists worldwide, especially in the tropical belt but also in high intensity agricultural zones in the Northern and Southern hemisphere. Usually those residual biomass feedstocks are used for incineration (energy production) or processed to animal feed. Yet, several types of lignocellulosic biomass are not digestible and thus left unused. The focus of Green Sugar is on lignocellulosic biomass since its use in the chemical industry avoids a conflict with the food sector and promotes food security.
Those parts of the plant which are not edible, especially wheat / rice straw, husks, bagasse but also grass, which contain a high concentration of polysaccharides, can be utilized by Green Sugar. Beyond that, forestry waste from the oil palm sector like empty fruit bunches and leafs, tree-tops and trunk waste from the bioenergy sector, as well as timber and residues from the pulp and paper industry are suitable for the Green Sugar saccharification process. There is no limitation for the Green Sugar process in terms of feedstock type.
Since all types of lignocellulosic biomass generally consist of the polysacharides cellulose, xylans and galactoglucomannans, they are a great source for polysaccharides. As soon as the carbohydrates can be accessed and transformed into monosaccharides, they serve as carbon source towards down-stream biotechnological processes leading to bio-based chemical products.
Renewable biomass can substitute fossil resources as the key source for many chemicals. One way of producing a wide range of chemicals starts with sugar. It can be processed in various fermentation routes towards amino acids, organic acids, polymers, alcohols, vitamins, or antibiotics.
Given the rapid technological development and proven biochemical processes, lignocellulosic biomass feedstock is a vital source for bio-based chemicals.
A great opportunity exists in the creation of new value chains with the help of bio-based feedstock as the starting point and biorefinery systems at the core of innovative ways of creating value. Green Sugar has developed a technology, which valorises residual biomass that is often left unused and usually treated like waste. Especially rural societies in regions with abundantly available residual biomass can benefit from the integrated value chain approach, reaching from the lignocellulosic biomass to high quality bio-based chemicals. This approach stimulates economic activity in rural areas and facilitates technology transfer in the chemical, biomass handling as well as other down-stream processing industries.
In an effort to decarbonise the world economy, at Green Sugar we strive for the substitution of petroleum-sourced products. We apply inspired science and test innovative chemical routes to deliver holistic, sustainable solutions for a low-carbon world.
Core sustainability principles of Green Sugar are the regeneration of the biosphere, efficiency of natural and chemical processes and the protection of the natural environment.
Rural economic development is not a given, but we explicitly seek the empowering of societies in each part of an integrated value chain, from the feedstock supply to the chemicals production. We seek to improve the lives of the communities where we operate by fostering social and community involvement.
Towards building a bioeconomy based on lignocellulosic biomass biorefineries, it is necessary to investigate various types of biomass feedstock and to test and advance down-stream biochemical fermentation routes.
Green Sugar investigates the suitability of biomass feedstock sources by applying chemical analyses. Further, we conceptualise and verify different down-stream fermentation pathways towards the production of bio-based chemicals.
