“…This raw material can be transformed into a wide array of bio-based fuels and products in the so-called biorefinery facilities. [3,4] Lactic acid (LA) is one of the industrially relevant bioproducts that can be obtained from biomass. This compound is a precursor of polylactic acid (PLA), which is an important component in bioplastic production with multiple applications in the food and pharmaceutical sectors.…”

In this study, the production of lactic acid from municipal forestry and greening wastes processed by steam explosion (SE) and enzymatic hydrolysis is addressed. The liquid fraction hydrolysate (LFH) obtained after filtration of the steam‐exploded slurry (previously subjected to detoxification) and the enzymatic hydrolysate resulting from the water insoluble solid fraction (WIS‐derived hydrolysate, WDH) are studied as substrate for lactic acid fermentation using an integrated strategy. The fermentation process of WDH using Bacillus coagulans and Lactobacillus rhamnosus shows similar sugar conversion yields of about 0.9 g g−1 (based on consumed glucose). In contrast, the use of detoxified LFH (d‐LFH) completely inhibits B. coagulans, making necessary a previous dilution with the WDH to trigger fermentation when using this microorganism. The best integrated strategy using both d‐LFH and WDH streams and B. coagulans as fermentative strain has a 1:3 d‐LFH:WDH ratio, yielding 0.93 g lactic acid g−1 of consumed sugars and a lactic acid concentration of about 50 g L−1.

“…Moreover, the linear economy model (extraction-production-use) has been gradually replaced by the concept of circular economy, which aims to maximize resource efficiency and waste reduction [3]. In this sense, implementing biorefineries is an indispensable strategy for executing the circular economy plan, as it will stimulate many economic opportunities, in addition to the sustainable transformation of waste into raw materials [4].…”

“…Even if there are some advances in the prospective study of biorefineries of cassava residues, it is still essential to evaluate the entire system's sustainability. In that sense, the life cycle assessment (LCA) is a systematic methodology (ISO 14000) widely used to identify the environmental effects generated by processes or products [4]. Therefore, this review gathers information on the recovery of these residues (peels, roots, bagasse, and wastewater), aiming to encourage the economic-sustainable recovery of these materials within the biorefinery concept.…”

Commonly known as a subsistence culture, cassava came to be considered a commodity and key to adding value. However, this tuber’s processing for starch and flour production is responsible for generating a large amount of waste that causes serious environmental problems. This biomass of varied biochemical composition has excellent potential for producing fuels (biogas, bioethanol, butanol, biohydrogen) and non-energetic products (succinic acid, glucose syrup, lactic acid) via biorefinery. However, there are environmental challenges, leading to uncertainties related to the sustainability of biorefineries. Thus, the provision of information generated in life cycle assessment (LCA) can help reduce bottlenecks found in the productive stages, making production more competitive. Within that, this review concentrates information on the production of value-added products, the environmental impact generated, and the sustainability of biorefineries.

“…Além disso, as biorrefinarias podem também utilizar resíduos de outras indústrias como matéria prima, como por exemplo o bagaço de cana-de-açúcar utilizado na produção de etanol. (YOON et al, 2019;IGBOKWE et al, 2022) Os processos de conversão inseridos no context da biorrefinaria podem ser químicos, como na produção do biodiesel a partir de óleos e álcoois, ou bioquímico, como é realizado na produção do bioetanol (IGBOKWE et al, 2022).…”
