“…The first represents a respected bibliographic database, since it provides a comprehensive coverage of recent studies [59]. Web of Science database is often used to improve the reliability of review studies [72], due to the high reputation of its indexed journals. In fact, almost 70% of the bibliometric studies rely on the WoS [73].…”

The importance of the circular economy has greatly increased in the past few years, and consequently, the interest in the circular economy as a research field has also increased, which led to an exponential growth in the number of literature reviews on the subject with different purposes. In order to analyze the topics that have been studied and assess the quality of these secondary reviews, this study carried out a tertiary literature review on the subject. This study identified the literature reviews on the circular economy, the most frequently cited papers, and the main research topics in the field. We have also analyzed the types of research questions that have been proposed by secondary studies. Finally, we evaluated the extent to which secondary reviews have assessed the quality of primary studies. We found out that literature reviews on the circular economy are frequently related to the areas of supply chain and technology. We also concluded that there is a need for designing research questions that explore more complex relationships, since most questions are descriptive or process-related. Some research questions are proposed to guide future studies. We also observed that secondary studies have failed to appropriately assess the quality of primary studies.

“…In the CE field, systematic reviews have been increasingly used to address con-ceptual questions related to definitional matters [9,51], sectoral specificities [53] and business setups [54][55][56], social aspects [57], as well as indicators and assessment techniques [58][59][60]. However, from an innovation perspective, contributions have been rather limited [11].…”

Eco-Innovation Diversity in a Circular Economy: Towards Circular Innovation Studies

et al. 2021

Transition to a Circular Economy (CE) is about structural change and is predicated on the introduction of transformative eco-innovation (EI). Research on the CE–EI nexus has recently attracted attention both from an analytical and regulatory perspective. However, in-depth research exploring EI dynamics within the CE is still marginal, especially concerning the trends and dynamics of the pro-CE innovation policy and strategy. This paper addresses this gap by taking advantage of the burgeoning research on CE of the last 20 years and offers a new working synthesis. By implementing a “(systematic) review of (systematic) reviews”, this paper provides a new comprehensive framework for understanding pro-circular innovation strategies and, as a complement, argues the need to advance “circular innovation studies” as an agenda in its own right. Innovations related to recycling and recovery CE strategies along with business-model innovations and systemic/transformative innovations are found to be a major current trend in the research, connecting supply and demand side innovations and also driving other forms of innovation linked to design, product manufacturing, logistics and reverse logistics and end-of-life management and recovery. Additionally, of note is that the conceptual understanding of EI dynamics within a CE is still mainly implicit (rather than explicitly discussed) limiting the possibilities to advance knowledge in the area of innovation for CE: this is why we propose a “circular innovation studies” agenda.

“…The recovery and valorization of compounds through green methodologies and from bioresidues, adding value to what would be wasted, corroborates the principles of a circular economy [ 99 ]. The circular economy is the concept related to the reduction, reuse, and recycling of food losses and wastes along the food supply chain [ 100 ]. The use of bioresidues to obtain value-added compounds is a management strategy for waste and food loss, which can contribute to reducing its environmental impacts, minimizing the use of virgin materials, in addition to promoting opportunities for savings, as innovation of products and methods, competitiveness and productivity [ 100 ].…”

Sustainable Recovery of Preservative and Bioactive Compounds from Food Industry Bioresidues

With the increasing demand for convenient and ready-to-eat foods, the use of antioxidants and preservative additives in foodstuff formulation is essential. In addition to their technological functions in food, bio-based additives confer beneficial properties for human health for having antioxidant capacity and acting as antimicrobial, antitumor, and anti-inflammatory agents, among others. The replacement of preservatives and other additives from synthetic origin, usually related to adverse effects on human health, faces some challenges such as availability and cost. An opportunity to obtain these compounds lies in the food industry itself, as a great variety of food waste has been identified as an excellent source of high value-added compounds. Large amounts of seeds, fibrous strands, peel, bagasse, among other parts of fruits and vegetables are lost or wasted during industrial processing, despite being rich sources of bioactive compounds. From a circular economy perspective, this work reviewed the main advances on the recovery of value-added compounds from food industry bioresidues for food application. Bioactive compounds, mainly phenolic compounds, have been largely obtained, mostly from seeds and peels, and have been successfully incorporated into foods. Additionally, alternative and eco-friendly extraction techniques, as ultrasound and microwave, have showed advantages in extracting antioxidant and preservatives compounds.
