“…An appropriate waste management helps to reduce not only the negative effects on the environment but also has got an important economic impact, since there is less production of nonrenewable resources and less energy is used in the production of new goods. Among food industry wastes, coffee by-products have been extensively taken into consideration for recycle [1][2][3][4][5].…”

Spent coffee grounds (SCGs), waste products of coffee beverage production, are rich in organic compounds such as phenols. Different studies have demonstrated phenol beneficial effects in counteracting neurodegenerative diseases. These diseases are associated with oxidative stress and neuroinflammation, which initiates the degeneration of neurons by overactivating microglia. Unfortunately, to date, there are no pharmacological therapies to treat these pathologies. The aim of this study was to evaluate the phenolic content of 4 different SCG extracts and their ability to counteract oxidative stress and neuroinflammation. Caffeine and 5-O-caffeoylquinic acid were the most abundant compounds in all extracts, followed by 3-O-caffeoylquinic acid and 3,5-O-dicaffeoylquinic acid. The four extracts demonstrated a different ability to counteract oxidative stress and neuroinflammation in vitro. In particular, the methanol extract was the most effective in protecting neuron-like SH-SY5Y cells against H2O2-induced oxidative stress by upregulating endogenous antioxidant enzymes such as thioredoxin reductase, heme oxygenase 1, NADPH quinone oxidoreductase, and glutathione reductase. The water extract was the most effective in counteracting lipopolysaccharide-induced neuroinflammation in microglial BV-2 cells by strongly reducing the expression of proinflammatory mediators through the modulation of the TLR4/NF-κB pathway. On these bases, SCG extracts could represent valuable nutraceutical sources for the treatment of neurodegeneration.

“…A Europe without waste") and changes in the business organisation processes themselves lead to changes in the fields of materials extraction, production, marketing, and recycling [29,30]. Keeping this in mind, many companies are modernising and reorganising traditional supply chains and moving from "linear" to "circular", thus reducing the consumption of material resources and energy, as well as the amount of waste generated [31][32][33].…”

In this paper, the authors identified key elements important for circularity. The primary goal of circularity is to eliminate waste and prove the constant use of resources. In the paper, we classified studies according to circular approaches and stated which of them get the highest attention. Further, we identified the principal elements, grouped them into four categories important for circularity, and presented scientific works dedicated to each of the above-mentioned categories. Further on, several core elements from the first category were investigated, aiming to connect different waste streams and provide a regression model. Finally, the methodological part reviewed the correlation between various types of waste and their recycling and selected suitable ones for developing a new panel regression model. The empirical research was delivered for the 27 European Union countries during the period between 2000 and 2019. We indicate that the recycling rate of municipal waste impacts the increase of recycling biowaste the same calendar year. The increase of recycling of municipal waste by one per cent means the increase of the recycling of biowaste by 0.6 per cent.

“…Products and services are rethought in the implementation of circular solutions based on durability, recyclability, reusability, repair, replacement, renewal, upgrading and reduced use of materials [6,31]. To avoid waste, increase resource productivity and decouple growth from natural resource consumption, companies need to apply these principles [37,42].…”

In this paper, the authors identified key elements important for circularity: (1) Background: The primary goal of circularity is to eliminate waste and to prove the constant use of resources. In the paper, we classify studies according to circular approaches. The authors identified main elements and classified them into categories important for circularity, starting with the managing and reducing waste and the recovery of resources; and ending with the circularity of material, and general circularity-related topics and presented scientific works dedicated to each of the above-mentioned categories. The authors analyzed several core elements from the first category aiming to investigate and connect different waste streams and provided a regression model; (2) Methods: The authors used a dynamic regression model to identify relationships among variables and selected the ones, which has an impact on the increase of biowaste. The research was delivered for the 27 European Union countries during the period between 2020 and 2019; (3) Conclusions: The authors indicated that the recycling rate of wasted electrical equipment in the previous year has an impact on the increase of recycling biowaste next year. This is explained as non-metallic spare parts of electronic equipment are used as biowaste for fuel production. And the separation process of the composites of electric equipment takes some time, on average the effect is evident in one year period.
