Abstract

EU’s bioethanol potential from wheat straw and maize stover and the environmental footprint of residue-based bioethanol

Highlights

The climate of our planet is changing as a result of emissions of greenhouse gases (GHGs) from the consumption of fossil fuels (Edenhofer et al 2011)
The total amount of residue from wheat and maize available for biorefineries is estimated at 81.9 Megatonnes (Mt) at field moisture weight, which is equivalent to 65.3 Mt as dry weight. The latter figure is very similar to the amount reported by Scarlat et al (2010), who estimated that maize and wheat together contribute 60% (i.e., 66.6 Mt) to the total of 111 Mt dry residue weight that can be sustainably collected in the European Union (EU)
The advanced bioethanol production potential in the EU was assessed per member state using country-specific wheat straw and maize stover production data

Summary

Introduction

The climate of our planet is changing as a result of emissions of greenhouse gases (GHGs) from the consumption of fossil fuels (Edenhofer et al 2011). The energy policy of the European Union (EU) requires a minimum of 14% of the final consumption in the transport sector to come from renewable sources by 2030 (European Commission 2018), contributing to the EU’s aim to be climate-neutral by 2050 (Council of the European Union 2020). To achieve these goals, the energy policy specifies a minimum target of 3.5% of the final transport sector’s energy consumption that shall originate from advanced biogas or biofuels (European Commission 2018).
