由于最近城市化，经济和全球人口的繁荣，世界范围内产生的废物数量急剧增加。世界银行估计，到2050年，全球产生的垃圾预计将增加70%。废物的处理已经成为一个主要问题，因为它对环境、人类健康和经济构成了风险。为了解决这一问题，并最大限度地发挥潜在的环境、经济和社会效益，废物增值——一种废物增值过程——已成为一种可持续和有效的策略。废物增值的主要目标是过渡到循环经济，并最大限度地减轻废物的危险影响。本文通过文献计量分析，构建了一个与五大废弃物流（食品、农业、纺织、塑料和电子）管理相关的研究主题共现网络。强调现代增值技术及其效率。此外，在可持续的环境、社会和经济表现方面，提出了对废物增值技术改进的见解。本综述总结了阻碍广泛采用废物增值的突出因素，如技术锁定、因地制宜、不利的法规和低投资，目的是设计解决方案，探索实际、可行和可持续的废物增值手段。
Due to the recent boom in urbanisation, economy, and global population, the amount of waste generated worldwide has increased tremendously. The World Bank estimates that global waste generation is expected to increase 70% by 2050. Disposal of waste is already a major concern as it poses risks to the environment, human health, and economy. To tackle this issue and maximise potential environmental, economic, and social benefits, waste valorisation – a value-adding process for waste materials – has emerged as a sustainable and efficient strategy. The major objective of waste valorisation is to transit to a circular economy and maximally alleviate hazardous impacts of waste. This review conducts bibliometric analysis to construct a co-occurrence network of research themes related to management of five major waste streams (i.e., food, agricultural, textile, plastics, and electronics). Modern valorisation technologies and their efficiencies are highlighted. Moreover, insights into improvement of waste valorisation technologies are presented in terms of sustainable environmental, social, and economic performances. This review summarises highlighting factors that impede widespread adoption of waste valorisation, such as technology lock-in, optimisation for local conditions, unfavourable regulations, and low investments, with the aim of devising solutions that explore practical, feasible, and sustainable means of waste valorisation.
