In Mexico, whey is discarded into drains without treatment, which represents an environmental problem. It is known that whey is a mixture of nutrients that increase biochemical demand (BOD) and chemical oxygen demand (COD), exceeding the limits established by national and international standards. Some uses of whey have been proposed to reduce the negative impact it produces on the environment. Some of these uses are the production of high‐value raw materials, separation of macromolecules of industrial interest, and the generation of energy, among others. The integral use of waste under a biorefinery scheme represents a viable alternative for the use of this waste. In this way, the chemical composition of the waste can be used to recover compounds with high added value. The main objective of this review is to propose a dairy whey biorefinery to use components of commercial interest. This biorefinery process involves three stages: the first is the separation of lactoferrin using a polyacrylamide matrix (PAM) impregnated with copper; the second is lactic fermentation using the residue resulting from the separation of lactoferrin, from which lactic acid, hydrolyzed proteins, and probiotics will be obtained. Finally, in the third stage, the residue from the previous stage can be used to generate biogas. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd

“…However, it requires enough of the (Fessenden and Van Amburgh, 2016). Of all the process discards, lactose and protein rich whey is considered one of the major ones in the cheese production (Bacenetti et al, 2018). Nonetheless, not only that whey powder production is highly expensive, but the process could also pollute the environment.…”

In the recent decades, air and surface water pollution by nitrogen from agro-industrial discards has become a global environmental concern. Generally, these byproducts and or discards are nutrient rich and could inexpensively be utilized for various purposes marginally helping with mitigation strategies. In this context, our study was conducted in two phases: producing lactosylurea from agro-industrial by-products and subsequently evaluating the possibility of using lactosylurea as a non-protein nitrogen source in the ruminant’s diet and its effect on feed digestibility as well as ruminal parameters. Gas production test and in-vitro disappearance method were used to describe the kinetics of digestion in both dry matter (DM) and crude protein (CP) of the four experimental treatments. Protozoa count and total volatile fatty acids concentration were utilized to evaluate the ruminal parameters. The treatments were 1) basal diet + urea (BDU), 2) basal diet+ lactosylurea (BDL), 3) basal diet+ concentrated lactosylurea (BDCL), 4) basal diet+ Optigen (slow release NPN) (BDO). According to our findings, produced gas, DM, and CP disappearance in were significantly higher in concentrated lactosylurea and positive control groups than the other treatments (P<0.05). Moreover, estimated metabolizable energy, digestible organic matter and short chain fatty Acid were significantly higher for the same treatments (P<0.05). The values for protozoa count (2.66×106 organism/ml) and total volatile fatty acids concentration (30.96 mmol/L) were significantly lower and for urea treatment compared with others (P<0.05). In conclusion, lactosylurea as agro-industrial by-products can be a good alternative for urea or Optigen to reduce environmental contamination.

“…Due to its high pI compared with other proteins present in cheese whey (Urtasun et al, 2018), it can be selectively adsorbed on cation-exchange materials, which is why ion exchange chromatography is the most common choice for LF purification (Doultani et al, 2003;Pochet et al, 2018;Wakabayashi, Yamauchi, & Takase, 2006). The processing of the remaining whey not only brings economic benefits to the producers but also has a beneficial impact on the environment since the dumping of huge volumes of whey causes environmental pollution (Bacenetti, Bava, Schievano, & Zucali, 2018;Nicolás, Ferreira, & Lassalle, 2019;Price, 2019). Nowadays, two protein products from cheese whey are marketed: whey protein concentrates (WPC) and whey protein isolates (WPI).…”
