“…However, the replacement of fossil fuels by renewable ones in the transport sector needs the development of efficient and sustainable industrial processes for their production. Furthermore, due to growing awareness of environmental pollution effects on climate change and humanity's health, there is increasing pressure for decarbonisation that leads to several new regulations, aiming to shift the utilisation of fossil fuels to biofuels and envisaging a more sustainable world [113].…”

Winemaking is one of the main Portuguese industries and has significantly grown in recent years, thus increasing the quantity of obtained residues. These wastes have a complex chemical composition and structure, and, for this reason, their treatment and valorisation are simultaneously a challenge and an opportunity. After an overview of the wine industry and its wastes, this article intends to review the different solid winemaking wastes, highlighting their chemical composition and structural characteristics, as well as their main potential applications. These wastes, such as grape stalks, can be directly applied as a source of bioenergy in the form of pellets or subjected to chemical/biological processing, resulting in valuable food additives, materials, or chemicals. Grape seeds provide food grade oil with potential biomedical applications. Grape skins are a promising source of biologically active substances. The sugar fraction of grape pomace can be biologically converted to a wide variety of bioproducts, like bioethanol, biogas, polyhydroxyalkanoates, and bacterial cellulose. The integration of the different processes into a biorefinery is also discussed, considering the characteristics of the Portuguese wine industry and pointing out solutions to valorise their wastes.

“…Cellulosic bioethanol is a second generation biofuel since its production does not interfere with the food chain and is one of the main alternatives to the first generation, obtained from food crops [158,160,161]. To promote the use of second generation biofuels, the EU established Renewable Energy Directive II, which defined a target of at least 3.5% of transportation fuels derived from advanced biofuels in 2030 [140,[162][163][164]. Moreover, the EU set out targets to limit the share of first generation biofuels to 7% by 2030 [162,163].…”

“…Therefore, solid loading optimization during pretreatment and enzymatic hydrolysis steps, onsite production of enzymatic consortium and integration of process steps are the main critical domain topics for further research [222]. Following a co-production strategy within a multi-product biorefinery could be a potential alternative to offset the high capital and production costs, improving competitiveness and representing extra revenues [37,164]. Some authors have studied some possibilities, namely the integration of the production of cellulosic ethanol with xylooligosaccharides [37,223,224] PHA [225], among others.…”

“…Overall, waste-based bioprocesses presented some challenges related to the intrinsic heterogeneity of feedstock. For that reason, the process should be flexible enough to ensure the quality of the final product, regardless of the variations in the process feed [164]. Moreover, the multi-product biorefinery seems to be a potential alternative to stimulate economic feasibility.…”

Getting Value from Pulp and Paper Industry Wastes: On the Way to Sustainability and Circular Economy

The pulp and paper industry is recognized as a well-established sector, which throughout its process, generates a vast amount of waste streams with the capacity to be valorized. Typically, these residues are burned for energy purposes, but their use as substrates for biological processes could be a more efficient and sustainable alternative. With this aim, it is essential to identify and characterize each type of waste to determine its biotechnological potential. In this context, this research highlights possible alternatives with lower environmental impact and higher revenues. The bio-based pathway should be a promising alternative for the valorization of pulp and paper industry wastes, in particular for bioproduct production such as bioethanol, polyhydroxyalkanoates (PHA), and biogas. This article focuses on state of the art regarding the identification and characterization of these wastes, their main applied deconstruction technologies and the valorization pathways reported for the production of the abovementioned bioproducts.
