“…All the studies we explored, which were published in 2018, presented some elements of wide analysis in terms of the typology of materials or environmental impact; however, they provided a rather limited overview of sustainable practices adopted by firms. Joshi et al (2021) conducted an LCA of a co-combustion system of single-use plastic waste and lignite coal to promote the CE. The sustainability and permeability of the novel cocombustion technique via co-processing were confirmed using the LCA results.…”

PurposeThis study analyzes sustainable practices adopted by Italian firms to enhance the circularity of packaging and related results in terms of environmental improvements.Design/methodology/approachThe authors developed an empirical analysis using publicly available data from the National Consortium of Packaging (CONAI) in Italy, which consists of 603 circular packaging projects. The authors ran both descriptive and prescriptive analyses to determine individual sustainable practices and portfolios adopted to enhance packaging circularity and to verify related reductions in terms of CO2 emissions as well as energy usage and water consumption.FindingsThe findings reveal that firms are more accustomed to focusing on single sustainable practices than on portfolios of practices to achieve packaging circularity. Raw material saving and logistics optimization are the most frequent sustainable practices adopted by firms to improve circularity of packaging. The reuse of packaging allows firms to simultaneously reduce CO2 emissions, energy usage and water consumption. Preferences in terms of portfolio of sustainable practices are strictly linked to the types of materials used for packaging and environmental targets.Originality/valueThe authors investigate environmental practices that firms adopt to support packaging circularity, and the authors detect portfolios of sustainable practices that positively impact environmental performance indicators. This research extends a significant glimpse into the portfolio of sustainable practices for packaging in the circular economy implemented by firms, filling academic gaps and indicating business opportunities and avenues for economic development.

“…Compared to coal-fired boilers, coal coupled with biomass combustion can effectively reduce CO 2 emissions. It also has lower costs for co-generation and can benefit from carbon trading, resulting in higher cost-profit ratios and both economic and environmental benefits [7]. Wang et al conducted numerical simulations on a 660 MW ultra-supercritical pulverized coal boiler in a power plant to explore the adaptability of biomass-coal co-firing under different loads [8].…”

This study explores the corrosion issues arising from the coupled combustion of coal and biomass and proposes potential solutions. Biomass, as a renewable energy source, offers advantages in energy-saving and carbon reduction. However, the corrosive effects of alkali metal compounds, sulfur (S) and chlorine (Cl) elements in the ash after combustion cannot be underestimated due to the high volatile content of biomass fuels. We investigate the corrosion mechanisms, as well as the transfer of Cl and alkali metal elements during this process. Comparative corrosion analyses are conducted among coal-fired boilers, pure biomass boilers and boilers with coupled combustion. Various biomass types in co-firing are studied to understand different corrosion outcomes. The main factors influencing corrosion include the physicochemical properties of biomass feedstock, furnace temperature and heating surface materials, with the chemical composition and ash content of biomass playing a dominant role. Currently, the methods used for anti-corrosion include water washing pretreatment of biomass feedstock, application of novel alloys and coatings and the development of additives to inhibit fouling, ash deposition and corrosion. Efficient inhibitors are economical and easy to produce. Additionally, biomass can be converted into biomass gasification gas, although challenges related to tar still need to be addressed.

The Association of Southeast Asian Nations is blessed with agricultural resources, and with the growing population, it will continue to prosper, which follows the abundance of agricultural biomass. Lignocellulosic biomass attracted researchers’ interest in extracting bio-oil from these wastes. However, the resulting bio-oil has low heating values and undesirable physical properties. Hence, co-pyrolysis with plastic or polymer wastes is adopted to improve the yield and quality of the bio-oil. Furthermore, with the spread of the novel coronavirus, the surge of single-use plastic waste such as disposable medical face mask, can potentially set back the previous plastic waste reduction measures. Therefore, studies of existing technologies and techniques are referred in exploring the potential of disposable medical face mask waste as a candidate for co-pyrolysis with biomass. Process parameters, utilisation of catalysts and technologies are key factors in improving and optimising the process to achieve commercial standard of liquid fuel. Catalytic co-pyrolysis involves a series of complex mechanisms, which cannot be explained using simple iso-conversional models. Hence, advanced conversional models are introduced, followed by the evolutionary models and predictive models, which can solve the non-linear catalytic co-pyrolysis reaction kinetics. The outlook and challenges for the topic are discussed in detail.
