This paper presents a review of sludge-to-energy and sludge-to-resources recovery routes with emphasis on recent developments, as well on the benefits and limitations of applicable technologies for ensuring sustainability and environmental efficiency through a critical analysis of current literature. In particular, improvement of anaerobic digestion final products exploitation, thermochemical technologies for sludge-embedded resources recovery, sludge biorefinery and nutrients recovery are discussed. In most cases, however, the technology readiness level (TRL) of the described technologies is still low for generalized adoption, hence, notwithstanding the excellent development prospects, it is probably still too early to predict the real impact of the many bioproducts recoverable from biological sludge on an actual global circular bioeconomy.</p></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"19 ","pages":"Article 200184"},"PeriodicalIF":0.0,"publicationDate":"2023-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49748248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This might prevent innovators from detecting unintended rebound effects that offset positive environmental gains of new business models. To mitigate this and let innovators think more profoundly about rebound effects during the circular business model experimentation phase, we propose an evidence-based business model ideation tool, the Circular Rebound Tool, designed around lifecycle thinking, the zero-waste hierarchy, and increased rebound effects awareness. The tool's development follows the design science research method, undergoing continuous improvement through 15 workshops. Our tool can help business innovators gain insights into the environmental impact of their early-stage business ideas.</p></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"20 ","pages":"Article 200185"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67739738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These short-term carbon savings are potentially detrimental to the long-term futureproofing of a building.

An adaptable building is one that could be easily modified to suit its changing requirements, allowing it to avoid premature demolition and reconstruction, and the associated carbon emissions. This paper explores what is meant by adaptability in the built environment, suggestions for design strategies and the benefits and drawbacks of each. The paper expressly emphasises the importance of balancing the needs of the present day, through upfront carbon reductions, with the consequences in the long-term, through accelerated building obsolescence, demolition and rebuild. The paper concludes with the recommendation that further research is needed into the true benefits of adaptability design strategies, factoring in the uncertainty of future predictions and the time-value of carbon.</p></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"18 ","pages":"Article 200158"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49869094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recycling demolition waste is thus a useful and practical way to conserve resources in the construction sector. For climate protection, it is important to investigate the material-induced grey energy of the recycling process. In this study we ask how grey energies induced by construction products based on secondary differ from equivalent products based on virgin materials. To evaluate this, we use a novel multi-stage assessment method presented in this paper. With this method, for the first time, we are able to calculate grey energy of entire recycling process chains starting from construction and demolition waste and ending with the new secondary material based building product, taking into account all the adjustments necessary to guarantee its functional equivalence to primary material based products. In 15 of the 19 process chains analysed, the use of RC material leads to in part rather significant positive grey energy impacts i.e. energy savings. In nine cases, the savings are over 50%, in six cases they are lower. The most important influential factors is the quality of both, the initial demolition material and the final construction product, defined by the product requirements. Furthermore, we conclude that an integrated recycling system is essential to ensure the recycling of co-products discharged during individual processing steps and provide evidence for further scientific discussion on how recycling can contribute to climate-neutral construction.</p></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"18 ","pages":"Article 200139"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49818101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As results, a matrix reporting the classes and typologies of waste, their EWC codes, their different WMSs and the suitable LCA processes from the Ecoinvent database that can be applied to each EWC within a specific WMS, has been developed.
