Solid waste management in small hotels: a comparison of green and non-green small hotels in Wales

Solid waste generation and disposal is one of the most negative impacts of small hotels on the environment. Small hotels often pay little attention to their environmental responsibilities. This research builds upon an earlier work by the same authors considering solid waste management (SWM) issues in small Welsh hotels. It considers the Welsh Assembly Government's Green Dragon Environmental Standard (GDES) as an environmental management system developed specifically to target small and medium-sized enterprises and help them with aspects of environmental management, such as SWM. It explores SWM practices in green (i.e. GDES-accredited) and non-green small hotels and develops a best practice SWM model for them. Semi-structured interviews were used to investigate hoteliers’ attitudes and the barriers to implement sustainable SWM practices. The findings revealed that most non-GDES small hotels were highly reliant on landfill for the disposal of solid waste and felt negatively about the implementation of more sustainable SWM alternatives. In contrast, GDES small hotels used landfill as a last resort and targeted other waste hierarchy options in preference. The study develops a best practice model for policymakers (local authorities and UK central government) to influence and encourage better SWM practices in small hotels.

Incentivizing sustainable waste management

The purpose of this paper is to contribute to the integration of economic and non-economic concepts of waste management and sustainability to achieve new insights to sustainable waste management. Since landfilling will continue to be a significant waste management method, our theory and practice of sustainable waste management should focus upon incentivizing the development of more sustainable landfills. The model sheds light on the design of efficient and fair landfill siting processes; how production inputs to bioreactor landfilling should be selected; and how management practices during the facility's operation phase can achieve greater economic, ecological and social sustainability.
