Anaerobic Digestion (AD) has been recognized as a viable solution to produce renewable energy and to reduce global warming especially when secondary feedstock and/or wastes are used. Several LCA studies analysed the environmental performances of biogas production systems. The results of this review highlight that the goal, scope, life cycle impact assessment (LCIA) methodology, feedstocks and geographical regions covered by the studies vary widely. Most studies are based in Europe, several in China and few in South and North America and in Africa. To better highlight how the choices on the feeding mix, the digestate storage, the surplus heat valorisation as well as the plant size can affect the environmental performances of agricultural AD plants four plants have been analyzed in this study. The results suggest that the energy crops production and the operation of anaerobic digesters, including digestate emission from open tanks, are the main contributors to the impacts from biogas electricity. This entails that it is environmentally better to have smaller plants using slurry and waste rather than bigger plants fed with energy crops. Recovering heat waste as well as covering of digestate tank would improve significantly the environmental sustainability of biogas electricity, and particularly the global warming category. We are pleased to enclose the revised version of our original manuscript of our paper entitled "Agricultural anaerobic digestion plants: What LCA studies pointed out and what can be done to make them more environmentally sustainable" which can hopefully be published in Applied Energy.Many thanks to the reviewers for their comments; they helped us to improve the manuscript.We hope that the manuscript in the revised form is appropriate for publication in Applied Energy.On behalf of all the Authors, as corresponding Author, yours sincerely, Cover Letter Title: Agricultural anaerobic digestion plants: What LCA studies pointed out and what can be done to make them more sustainable Dear Editor, we would like to thank you for the reviewers' comments. We are grateful to all the reviewers for devoting their time to review our manuscript. As you can see, we have taken most of them into consideration to modify the paper. We hope that the paper in this current revised version can be accepted for publication. Below, we enclose an explanation of how we have addressed the questions raised. Reviewer #1The manuscript is working on the review of the environmental impacts of biogas production. It includes good results, an interesting methodology, and related to the scope of this Journal. I suggest to accept it after some minor revisions. Thank you for your positive comments and for useful suggestions.The authors should write about the difference between their study and the following research: * Hijazi, O., Munro, S., Zerhusen, B. and Effenberger, M., 2016.

The study aims to explore the dynamic relationships between Water‐Energy‐Food (WEF) resources, carbon‐fossil‐GHG emissions, and growth specific factors in the context of Pakistan by using an annual time series data from 1970 to 2016. The results of simultaneous Generalized Method of Moments (GMM) estimator show that industry value added largely influenced water's share in carbon emissions and fossil fuel combustion, while chemicals that used in manufacturing value added largely increases water's GHG footprints in a country. The inverted U‐shaped Environmental Kuznets Curve (EKC) relationship confirmed for water's carbon footprint and food's carbon‐fossil‐GHG footprint with a turning point of EKC per capita income at US$1120, US$1170, US$1250, and US$1140, respectively. The U‐shaped EKC is substantiated by water's share in fossil fuel and energy's carbon‐fossil‐GHG footprints, while monotonic increasing functions is established with per capita income and water's share in GHG emissions. The Pollution Haven Hypothesis (PHH) is verified in case of water's share in carbon emissions, while IPAT hypothesis is substantiate in water's carbon footprint, food's carbon‐fossil‐GHG footprints, and energy's carbon‐fossil footprint. © 2018 American Institute of Chemical Engineers Environ Prog, 38:e13132, 2019

Abstract:The vast and ever-growing amount of agricultural and food wastes has become a major concern throughout the whole world. Therefore, strategies for their processing and value-added reuse are needed to enable a sustainable utilization of feedstocks and reduce the environmental burden. By-products of potato, tomato, cereals and olive arise in significant amounts in European countries and are consequently of high relevance. Due to their composition with various beneficial ingredients, the waste products can be valorized by different techniques leading to economic and environmental advantages. This paper focuses on the waste generation during industrial processing of potato, tomato, cereals and olives within the European Union and reviews state-of-the-art technologies for their valorization. Furthermore, current applications, future perspectives and challenges are discussed.
