COVID-19 has imposed significant detrimental effects on the global hospitality sector. These effects have primarily been considered from the socio-economic perspective, ignoring the implications of the pandemic for the environmental performance of hospitality services. By drawing upon emerging evidence from various academic and non-academic sources, this conceptual paper critically evaluates the implications of the preventative and protective measures adopted against COVID-19 for the generation of the hospitality sector's food and plastic waste. The implications are divided into direct and indirect and considered through the prism of temporality of their anticipated occurrence (immediate, short-term and medium-term perspective). The paper proposes potential strategies to aid in the management of these wastes in the hospitality sector in a post-pandemic world. To address the issue of food waste, the hospitality sector should be integrated into alternative food networks (AFNs) and short food supply chains (SFSCs). Business coopetition between hospitality enterprises and other actors of the food supply chain is necessary for the success of such integration. To address the issue of plastic waste, the hospitality sector should invest in ‘green’ innovation. This investment needs to be encouraged and supported by targeted policy interventions. The paper argues that these strategies are critical not only in the context of the COVID-19 pandemic, but will also remain valid for the sustained development of the hospitality sector in light of future disastrous events, especially climate change. The paper discusses the institutional and organisational prerequisites for the effective implementation of these strategies and highlights the related research opportunities.

COVID-19 对全球酒店业造成了重大的不利影响。这些影响主要是从社会经济角度考虑的，而忽略了大流行对酒店服务环境绩效的影响。通过借鉴来自各种学术和非学术来源的新证据，这篇概念性论文批判性地评估了针对 COVID-19 采取的预防和保护措施对酒店业食品和塑料垃圾产生的影响。影响分为直接影响和间接影响，并通过预期发生的时间性棱镜（即时、短期和中期视角）来考虑。该文件提出了可能的策略，以帮助在大流行后的世界中管理酒店业的这些废物。为解决食物浪费问题，酒店业应纳入替代食品网络 (AFN) 和短食品供应链 (SFSC)。酒店企业和食品供应链其他参与者之间的商业合作对于这种整合的成功是必要的。为解决塑料垃圾问题，酒店业应投资于“绿色”创新。这种投资需要有针对性的政策干预来鼓励和支持。该论文认为，这些策略不仅在 COVID-19 大流行的背景下至关重要，而且鉴于未来的灾难性事件，对于酒店业的持续发展也仍然有效，特别是气候变化。本文讨论了有效实施这些战略的制度和组织先决条件，并强调了相关的研究机会。
