Introduction: Nowadays, organic waste utilization and replacement of fossil energy sources with their renewable alternatives pose a challenging problem both for industrially developed and developing countries. Anaerobic digestion of organic biomass into biogas is considered an efficient technology for bioenergy production. Over the period from 2009 to 2018, the global biogas production capacities have more than doubled and are continuing to grow. The composition and the amount of biogas depend strongly on the type of the substrate. Various types of feedstock can be used for the production of biogas such as animal wastes, agricultural residues, and dedicated energy crops. Objective: To review biogas production potentials of energy crops and plant processing raw materials. Results: In the background of historical development and present state, the paper reviews the potential of different plant raw materials to be utilized for biogas production purposes. The potential of energy crops, agricultural residues, and wastes for biogas production is analyzed. International projects concerning energy crops grown on marginal lands are presented and commented on in the article. The approach of implementing crop rotation systems for industrial energy crop cultivation is described and recommended as beneficial for various purposes. The anaerobic degradability of biomass constituents, optimal process parameters, and biomass treatment for biogas production are discussed. C/N ration and lignocelluloses content in the substrate are considered among the most decisive parameters for AD and methane production. Various concepts of biogas bioreactor technologies have been studied depending on the substrate type. Conclusion: Plant feedstock may play a decisive role in biogas production as a renewable energy source. To avoid GHG release into the atmosphere, biogas facilities should be built within the closest vicinities to the places of existing garbage dumps, and waste management practice involving organic fraction separation in households and in the industry should be applied. Construction of biogas facilities is beneficial for environmental, economic, and social reasons.

“…This is particularly true for food chains and local and organic products (Caputo et al, 2017) in sustainable rural areas (Grippo et al, 2019). Proximity is also useful for fuel, energy and heat recovery from plants (Cucchiella et al, 2019), contributing to symbiotic systems (Renzulli et al, 2016), even if larger decentralised plants are sometimes advantageous (Lombardi et al, 2015).…”

Life cycle assessment applied to waste management in Italy: A mini-review of characteristics and methodological perspectives for local assessment

Life cycle assessment (LCA) and related tools are commonly used to evaluate the potential environmental impacts of waste treatment scenarios. This manuscript presents a mini-review of studies published over the last 10 years in Italy and aims to investigate how life cycle thinking tools are applied to assess the environmental sustainability of local-level waste policies. Results reveal that different waste flows, technologies and policies have been investigated independently and in varying detail. Review suggests that boundary selection significantly affects LCA results; integration of different waste systems is therefore crucial to avoid spatial or temporal shifts of environmental impacts. Moreover, the description of methodological characteristics, limitations and transversal aspects of Italian waste management studies allows various stakeholders to assess the reliability of past and future research for waste policy planning and rebound effects prevention. This review also highlights the need to define minimum requirements of transparency and ease of reporting of the studies to private and public stakeholders. Finally, the paper investigates whether using both the organisational LCA and the life cycle sustainability approach for the overall waste management process may be useful to develop a standard method to address multi-functionalities and multiple sites.

“…Non-state actors such as social groups, civil bodies, and intermediary organizations collaborate and exchange knowledge to narrow the gaps in the UK government's top-down policy approach (Markantoni, 2016). In contrast to the UK, local municipalities in Italy use the decentralized BfW scheme structure, thereby improving the recycling rate at the city level and supporting the local low-carbon economy (Cucchiella et al, 2019).…”

“…In contrast to the UK, other European countries like Italy and Sweden plan decentralized and localized BfW scheme. In Italy, local municipalities at the city level recycle their own waste material to generate biogas, thereby, support a local CE model by closing the loop to improve resource efficiency and utilize produced biogas for energy and digestate as fertilizer (Cucchiella et al, 2019). As per the Swedish national biogas strategy, the Energigas Sweden (2018) reported 1) biogas plants should be located close to waste collection points to increase commercialization of the BfW scheme, 2) local municipalities should take overall responsibility for the BfW scheme.…”

The biogas from waste has emerged as a realistic and reliable renewable energy proposition and can deliver social-economic benefits when integrated with local communities. In the last decade, the biogas sector in European countries has seen unprecedented growth due to favorable policy supports and perceived social-economic benefits. Among different biogas producing schemes, waste to biogas using anaerobic digestion is considered most environment friendly due to minimum carbon leakage and positive waste resource recycling impact. Many countries, including the UK, envision creating a circular economy utilizing Biogas from Waste (BfW) recycling potential. This paper aims to analyze the state of the UK’s BfW scheme through the lens of circular economy and discern areas that need attention to usher BfW potential in supporting a circular economy. The paper also discussed key challenges and barriers to create a local circular economy using the BfW scheme. Based on the analysis, it is observed that the BfW scheme in the UK is currently impeded due to lack cross-sectoral policy coherence, and far from contributing to a circular economy. Additionally, the UK's waste to energy concept is concentrated around incinerator-based systems without much attention on improving resource efficiency and waste recycling. This paper makes three recommendations to improve prospects of the BfW scheme in the UK (1) decentralized approach in the BfW scheme development, (2) considering bio-waste and digestate as value streams, and (3) creating a policy cohesiveness across multiple departments.
