SUSTANABILITY ASPECTS IN ROOM DESIGN

Designed with sustainability in mind, our Deluxe, Premium Deluxe and Deluxe Park View rooms feature repurposed and reused furnishings, reinforcing some of their former accoutrements and accessories. They were reworked in look and feel to enhance their urban, contemporary aesthetics, and to create a modern and serene space.

BEHIND THE SCENES

A pioneering sustainability initiative is the rooftop herb garden, cultivated by Executive Chef Péter Bárdos and his kitchen team. ÉS Bisztró and the hotel’s kitchens source fresh herbs and vegetables directly from this garden. Among the plants grown are tomatoes, paprika, lovage, thyme, tarragon, rosemary and various mints.

More than 80% of the hotel’s business partners and suppliers are domestic. The hotel prioritises regional products, local services and fair-trade practices to reduce environmental impact.

The hotel purchases only free-range eggs, with animal welfare in mind. For The Living Room, only Heppenheimer eggs are used, sourced from hens fed on locally grown corn, wheat, sunflower and other natural grains. These feeds are GMO-free and contain no medication, colouring agents or soy.

Waste is sorted and collected separately: baled paper, plastic bottles, communal waste, glass, food residuals, used cooking oil and dry-cleaning waste are regularly collected and properly processed.

Since 2018, the hotel kitchen has utilised Granuldisk dishwashers, which use on average 70% less water, energy and chemicals than traditional pot-washing methods.

The hotel’s laundry uses phosphate-free detergents to prevent nutrient pollution and harmful algal blooms. (Phosphates can remain in wastewater and eventually enter natural bodies of water.)

Motion sensors are installed in select areas to ensure lighting is activated only when necessary, conserving energy.
 

GUEST AREA

The hotel purchases decomposable plastic cutlery and drinking straws from ecologically responsible manufacturers. Detergent bottles are collected and recycled for reuse.

Since 2020, plastic cocktail pickers, stirrers and packaging for all bathroom amenities (hygiene sets, emery boards, cotton buds, cotton pads, etc.) have been replaced with sustainable alternatives such as paper-wrapped items or wooden materials, wherever possible. Kempinski’s liquid bathroom products by Ferragamo are presented in packaging made from 100% recycled plastic.
 

Bedlinen is changed every second day. Guests who wish for a daily change may place the handmade Green Linen Artefact on the bed. Depicting a bird with a flower—a well-known Hungarian folk motif—the design symbolises peace, nature, and eternity. The accompanying card raises awareness of both environmental and cultural values. Guests may also purchase the artefact, with proceeds supporting environmental conservation projects in Hungary.

In autumn 2021, the hotel transitioned to wooden key cards, replacing traditional plastic ones.

Energy-efficient LED lighting has been introduced throughout the hotel, replacing conventional bulbs and signage to reduce energy consumption.

Kempinski Hotel Corvinus Budapest was the first hotel in Hungary to install public electric vehicle charging stations. Located in the hotel’s underground car park, six high-quality, fast 22 kw chargers are available for public use.

An environmentally conscious hydration solution crafted in Sweden, Nordaq filtered water is offered to guests in ÉS Bisztró and during banqueting events. This premium water, free of impurities and off-flavours, is available still or sparkling. It retains natural salts and minerals for a balanced and refined taste. In guest rooms, Purezza water has been introduced—an innovative and sustainable solution that purifies tap water through high-quality filtration. 

The hotel orders the majority of its printed materials from Folprint, Hungary’s first and oldest green printing house, which holds FSC certification. Folprint uses sustainably sourced raw materials, and their printing processes are fully carbon neutral.

To reduce printed materials, restaurant and in-room dining menus are also accessible in digital format..
 

CLEAN THE WORLD

Kempinski has partnered with Clean the World, an organisation that collects and recycles soap bars and bottled amenities discarded by the hospitality industry.

By joining Clean the World, we ensure that our toiletries do not end up in landfills or incinerators. Through the distribution of these and other donated hygiene products to communities in need, we help prevent millions of hygiene-related illnesses and deaths each year. Clean the World provides at-risk individuals with access to soap, along with education on proper hygiene practices. The programme significantly reduces waste and promotes a more sustainable future.

Clean the World collects used amenity bottles and soap bars from our hotel. Liquid hygiene products are extracted from the bottles for reuse, and the bottles themselves are recycled through a state-of-the-art process that produces high-purity recycled plastic –supporting a circular economy. Soap bars are sanitised, remoulded into new bars, and distributed to communities in need, including benefit shelters, children’s homes, refugee camps, and individuals affected by poverty, misfortune, or natural disaster.
