“…Taking the biodiesel industry into account, the search for novel high value-added products based on glycerol is a topic that deserves attention, mostly because its industrial surplus has induced an unneglectable market saturation. Glycerol ethers, for instance, meet the renewable green solvent requirements and have attracted a great deal of attention in various applications [ 108 ]. Glycerol microbial biotransformations, mainly into dihydroxyacetone, are also in the spotlight [ 109 ].…”

A progressively increasing concern about the environmental impacts of the whole polymer industry has boosted the design of less aggressive technologies that allow for the maximum use of carbon atoms, and reduced dependence on the fossil platform. Progresses related to the former approach are mostly based on the concept of the circular economy, which aims at a thorough use of raw materials, from production to disposal. The latter, however, has been considered a priority nowadays, as short-term biological processes can efficiently provide a myriad of chemicals for the polymer industry. Polymers from renewable resources are widely established in research and technology facilities from all over the world, and a broader consolidation of such materials is expected in a near future. Herein, an up-to-date overview of the most recent and relevant contributions dedicated to the production of monomers and polymers from biomass is presented. We provide some basic issues related to the preparation of polymers from renewable resources to discuss ongoing strategies that can be used to achieve original polymers and systems thereof.

“…The standard molar enthalpies of formation, Δ f o H m ° , are indispensable to estimate reaction enthalpies and optimize heat management in chemical technology. In our recent work, we have shown that the enthalpies of formation of GE compounds in the gas phase can be reliably calculated using the high-level QC methods. In this work, we used the G4 and the G4MP2 methods to calculate the Δ f H m ° (g) values of GE-1 – GE-4 .…”

Glycerol offers vast potential for the design of new “green” solvents and molecular building blocks from naturally derived resources. Etherification of glycerol at one or more of the three alcohols yields large decreases in viscosity and makes the resulting products attractive “green” solvent candidates. Our prior works have demonstrated efficient synthesis of 1,3-diether-2-alcohol, 1,3-diether-2-ketone, and 1,2,3-triether compounds with glycerol skeletons with a variety of functional groups in both symmetric and asymmetric patterns. As the potential applications for these compounds become more widely explored, there is a need to understand their properties so that they may be properly evaluated for use in existing and new process technologies. In this work, the thermodynamic properties of four glycerol ethers with systematically varied functional groups are measured and evaluated. Data reported will not only help supplement the library of glycerol derivative properties, but also provide guidance for the development of novel biofuel additives.

“…It can also be used in the food industry, as an additive, or to produce triacetin, which constitutes cigarettes, or even in the production of nitro-glycerine. From the energy point of view, it can be used both as a carbon source in anaerobic digestion processes and as an energy vector in catalytic processes for hydrogen production (Tabatabaei et al 2019;Andreeva et al 2022;Khademi and Lotfi-Varnoosfaderani 2022).…”

PurposeThe olive oil sector in Italy has a significant socio-economic, environmental, and cultural relevance. However, the environmental impacts of production and consumption models are considerable, mainly due to the demand for large quantities of resources (fuels, chemicals) and to the environmental impacts of residues' disposal. Due to the scarcity of resources and climate change concerns, circular economy principles based on industrial ecology concepts are emerging. In this paper, the principles of circular economy were specifically applied to the olive oil supply chain, to improve the environmental sustainability of the sector. Methods The production chain of extra virgin olive oil was analyzed using the Life Cycle Assessment method, based on primary data from an oil farm and mill in Southern Italy. The environmental impacts were evaluated through the SimaPro software and the ReCiPe 2016 Mid-point (H) Impact Assessment Method, with reference to the functional unit of 1-L bottle of extra virgin olive oil. Some circular improvement options were investigated, comparing the impacts generated by (i) extra virgin olive oil linear production without valorization of by-products, (ii) extra virgin olive oil linear production with allocation of total impacts to co-products, and (iii) two circular production systems, incorporating improvements such as replacement of diesel with biodiesel and of electricity from the national grid with energy recovered from residues. Results and discussionThe environmental impacts of the business-as-usual production pattern were identified for possible improvements. In all phases of the production chain of organic extra virgin olive oil, the most affected impact categories were human carcinogenic toxicity, marine ecotoxicity, and terrestrial ecotoxicity. As expected, the major contributions to almost all the analyzed impact categories were determined by the agricultural phase (92.65%), followed by the bottling phase (7.13%) and the oil extraction phase (0.22%). The valorization of by-products was considered by widening the system boundaries to ensure the environmental sustainability by developing circular patterns that feedback waste materials to upstream steps of the same process. The environmental impacts resulted lower in almost all the impact categories, with the major benefits gained in the global warming and fossil depletion impact categories. Conclusions The analysis proved that the reuse of pomace, prunings, and exhausted cooking oil initially considered as waste can bring benefits from an environmental point of view to the larger scale of the economy, by replacing fossil fuels, as well as to the olive oil chain itself, by providing the needed energy for production.
