“…Even approximately 2 ppm of acrolein exhibits strong toxicity. The lower exposure limit of acrolein recommended by an ecological report is as low as 0.09 ppm [10]. Table 1 presents the relevant physicochemical properties and toxicity data of glycerol reported in different studies [1,9,11].…”

“…However, glycerol obtained directly from this process has low purity, which is an undesired product for chemical and pharmaceutical applications without pretreatment [71]. As pointed out by Coronado et al [72], molecular properties as well as impurities in crude glycerol hinder its use as fuel for generating heat and power for the biodiesel production process, as it uses by-products of other biofuels such as ethanol. Glycerol is also a very suitable substrate for bacterial growth, with several different organisms being able to use it as sole carbon source to produce several different commodities.…”

There is a pressing need for renewable and optimal use of resources towards sustainable primary production and processing systems worldwide. Current technologies for food and feedstock production are held accountable for several environmental problems, such as for instance soil and water contamination due to the use of hazardous substances, generation of toxic products and even excess of biomass that is considered waste. To minimize or solve these questions in order to produce an adequate quantity of reliable and healthy food, fibers and other products and energy, new paradigms focusing on sustainable agriculture, bio-based industries or biorefineries have emerged over the last decades. Biorefineries integrate sustainable and environmentally friendly concepts of Green Chemistry with intelligent and integrated farming processes, optimizing the agricultural production. Thermochemical and biochemical processes are excellent alternatives for the production of new classes of renewable biofuels and feedstock, showing relatively small impact on greenhouse gas emissions and important pathways to obtain platform chemicals. This review discusses the current and incipient technological developments for using biomass to generate bio-based chemicals over the last decade, focusing on Green Chemistry concepts towards sustainable agriculture and processing models in Brazil.

“…Moreover, Colorado et al [36] investigated the environmental impact of glycerol combustion in boilers to produce thermal energy and cover the biodiesel production plants needs. The group of researchers concluded that commercial glycerol namely USP) has the best ecological efficiency, while demethylated and methylated glycerol follow.…”

Crude glycerol is the principal by-product of biodiesel industry, accounting for 10 wt% of biodiesel production. As the production of biodiesel grows, the environmental and sustainable valorization of crude glycerol becomes an imperative task which affects directly the biodiesel production cost. The present study focuses on covalorization of crude glycerol with conventional and/or renewable resources. The use of pyrolysis and gasification, as waste management practices, closing the loop in energy and agriculture, by using the extracted oil for biodiesel production and the remaining residual biomass for combined heat and power generation, has great potential in a circular economy. The paper is of scientific interest as it investigates the valorization of glycerol waste streams produced from small-scale biodiesel plants, targeting to an effective management solution of the above streams in countries such as Greece, where a chemical biorefinery is not viable due to small availability of glycerol supply. Results have shown that co-valorization of crude glycerol with waste biomass fulfilling the energetic needs of the biodiesel plant within the boundaries of the company, can contribute in decreasing the cost of biodiesel production, while providing a rather short-term solution to the existing environmental problem of waste glycerol.
