Introduction

Most biorefineries define “the purpose of pretreatment is to destroy the structure of cellulosic biomass plant cell walls and make cellulose more accessible to the subsequent process“[1]. A variety of schemes have been developed, but none of them specifically targets the recovery of the hemicellulose (and the lignins) at that stage. In contrast, DalinYebo’s sole interest is the conversion of the pentosans, i.e. the majority of the hemicelluloses, into value added chemicals, thus removing them from the biomass. The resulting residue is then available for downstream processing and can be conditioned for specific applications.

Turning (perceived) Costs into Revenue

The core of our pretreatment platforms is the production of furfural. Whilst we have a preference for certain biomass feedstock, our R&D and project experience has provide us with vast knowhow to determine The-Right-Balance™ for any biorefinery in terms of the mass and energy balance, which determines the economics of a biorefinery. By producing a saleable product – for which we have market access – we turn what currently is perceived to be a cost into revenue in support of the production of its principal product (e.g. bio-ethanol, cellulosic ethanol, bio-diesel, bio-gas, green electricity, dissolving pulp, etc.)

Our site has moved to a new platform. It is functional, but expect the odd 'hiccup' (e.g. there are over 300 links and references that we are busy editing). Please continue to use it and/or submit your details and we'll notify you once all is 100% up and running.
