Abstract

This article aims towards the development of a technology roadmap related to anaerobic digestion and biogas production from straw. A technology roadmap is a strategic tool that describes clearly links between tasks and priorities for action in the short, medium and long-term. It also offers an effective script that connects technology, products, and markets at high levels of abstraction. As a result, the technological state of the company can be maintained or improved. The process to obtain biogas is mainly used for the disposal of organic waste such as lignocellulosic residues. Thus, it is being promoted as an interesting low-carbon energy source to reduce the dependence on fossil fuels. Our findings highlight the prevalence of Chinese actors and suggest that multinational players, which are not known for biogas production, demonstrate the interest in biogas production from straw, elucidating possible long-term strategies.

INTRODUCTION

This research prioritizes the elaboration of a Technology Roadmap for the anaerobic digestion of straw and subsequent biogas production. A prospective technology study such as this is required for the acquisition of information concerning the state of the art of the technologies related to this sector, the areas that lack research and which ones are most exploited. Therefore, the roadmap obtained through this study makes it possible to identify windows of opportunity and to study the best focus for investment allocation.

Straw and Biogas Production

In recent decades, changes in oil prices and increasing global energy demand have intensified the search for alternative energy sources (1). Climate change, caused mainly by increased emissions of greenhouse gases (GHG) and the use of fossil fuels, has led to a significant interest in fuels and chemicals produced from renewable raw materials. There is a promotion of biomass-derived fuels as being low-carbon energy sources with the potential to reduce dependence on fossil fuels (2).

Straw is an agro-industrial residue that lacks appropriate dispo ...
