Cactus Hotels & ReHORECA: Partnership for the Circular Economy and Sustainable Waste Management

BUSINESS: 385 PRACTICES
The company Theofilos Chalkiadakis S.A. has been active in the hospitality industry since 1980. The investments of all these years in the construction of new modern hotel units are many. It is worth noting that the company has invested in the construction of two new hotel complexes in the last two years, with Cactus Bay welcoming its guests in the summer season of 2018 and continuing with Cactus Mare in the summer season of 2019 while at the same time they continue the renovations and the creation of additional infrastructure at Cactus Royal 5 * & Cactus Beach 4 *.
The initiative of Cactus Hotels in collaboration with the non-profit company ReHORECA aims to create an integrated system of circular economy and waste management in the hotel sector.
The modern trend in the tourism product “imposes” the adoption of sustainability practices and methods, with the least possible environmental burden.
At the same time, the trend in destination choice by visitors/tour operators is shaped on the basis of the environmental characteristics of each property and, more broadly, of the region. According to the GSTC organization, a large percentage of visitors choose accommodations according to their environmental footprint.
Based on a “business-as-usual” scenario developed by the UN Environment Programme, global tourism is expected by 2050 to record an increase of 154% in energy consumption, 131% in greenhouse gas emissions, 152% in water consumption, and 251% in solid waste disposal.
The cooperation with the NGO ReHORECA was established mainly with a vision: to organize and implement a customized model of environmental management in hotel establishments, large catering structures, and staff gathering spaces, with the aim of reducing resource waste. At the same time, it created a way of implementing the necessary actions that can be certified mainly on the basis of results, in order to make the environmental character of each property clear to the guests, with objective measurements on real results (weighing logs), which will lead to top certifications and awards. However, the greatest reward ultimately comes from the guests themselves, those who will choose the Cactus Hotels chain based on the environmental impact, since the goal of reducing the waste of essential and non-renewable resources will be achieved at high levels.
The methods applied are personalized and fully adapted to the needs of each requirement and according to the operation and needs of each property. At the same time, a detailed environmental plan is drawn up, which defines the goals but mainly describes and ensures how these goals will be achieved.
The nature of the cooperation guarantees that the services provided will be absolutely clear, easy to implement, with immediately measurable results and low cost.
Key goals are:
The initiative of Cactus Hotels in collaboration with ReHORECA is addressed to:
Implemented from July 2025 to the present, with continuous action, monitoring, and improvements across all Cactus Hotels.
The initiative of Cactus Hotels in collaboration with ReHORECA, which began in July 2025, was designed with the purpose of adopting an integrated system of circular economy and sustainable waste management in the hotel sector. This cooperation represents a strategic choice, with the CEO of Cactus Hotels, Mr. Nikos Chalkiadakis, as a founding member, and is based on the need to reduce environmental footprint, optimize resource use, and enhance environmental awareness at all operational levels.
Environmental and Waste Management:
Each hotel unit of the group and in general the public service areas generate waste, a large percentage of which can be recycled. The goal is to approach “Zero Waste,” zero waste production to landfill, through a series of partnerships and management measures. The interventions are practical, with daily recording and analysis. They concern daily life and continuous operation (a hotel is considered to need support 12 months a year).
Each hotel produces per guest-night from 1.5 to 3.0 kg of waste, of which 25% could be avoided. The remaining unavoidable waste will be separated and collected daily (according to the stream), with the aim of timely management (timely management produces higher quality secondary, recycled product). Food that has not been served and therefore has not become waste will be delivered to food preparation units for social purposes, and the rest to the respective specialized waste management and circular economy bodies according to ReHORECA contracts and requirements. At the same time, separation of waste from rooms (contractual obligation since 1.1.2023) will be adopted and extended to all areas into separate and distinct streams.
Implementation is based on three pillars:
