After a year on Clean the World's Global Hospitality Recycling Program, we look back at what Radisson Hotel Manchester City Centre, A Verified Net Zero Hotel, has achieved.
The Radisson Hotels team shared how the program works in daily operations and how it supports the hotel's Verified Net Zero commitment.
Before the hotel joined the program, its used bathroom amenity bottles were not managed in the optimal way.
The hotel joined Clean the World's Global Hospitality Recycling Program on 21 May 2025. A year on, the 252-room hotel has a separate, measured record of this waste stream.
It is a fitting place to start. The hotel opened in May 2025 as Radisson Hotel Group's first Verified Net Zero hotel(1). Radisson’s Verified Net Zero program addresses emissions across Scopes 1, 2 and 3, including those associated with waste and purchased bathroom amenities, and is independently verified by TÜV Rheinland(2). Radisson aims to reach 100 Verified Net Zero hotels by 2030(2).
Choosing a partner for amenity waste was a deliberate decision. As the Radisson Hotels team explained:
"[Clean the World] has been on our radar for several years, was working with other hotels in the portfolio and was identified as a strong partner for the [Verified Net Zero] program."
How the Program Works at Manchester
The program runs in six steps, shared between the hotel team and Clean the World:
- HousekeepingSeparate
Housekeeping collects used bathroom amenity bottles separately from the rest of the room waste.
- HousekeepingFill
The bottles go into dedicated Clean the World collection boxes, kept apart from general waste.
- HousekeepingRequest
When boxes are full, the team uses the Clean the World Customer Portal to request a collection and order replacement boxes.
- Clean the WorldCollect
Clean the World collects the full boxes from the hotel and weighs each collection.
- Clean the WorldRecord
The collection data is uploaded to the hotel's account, building a record of everything returned through the program.
- RadissonMonitor
The operations team oversees the process, and Radisson can follow the hotel's collections over time to support better-informed decisions.
Each team has one clear job. That clarity is what keeps the record consistent, and the portal gives the hotel direct access to its data.
A Year in Numbers
A Waste Stream That Can Inform Better Decisions
Before the program, this material had no place in the hotel's waste information. Now Radisson Manchester has a quantified view of its bathroom amenity material, recorded collection by collection.
Seven collections, on average roughly every two months, show the program working steadily across the year.
That visibility supports sharper questions:
- how collected volumes move with occupancy
- how amenity choices show up in what is collected
- whether collection arrangements match the rhythm of the property
- how much waste is produced
- how even more waste can be prevented
- how much liquid residue is still present, and whether this can inform new internal operational SOPs to save costs
Working with Clean the World to process our bathroom amenities is a simple but impactful action that supports our Verified Net Zero commitment.
Why This Matters for Hotels Now
Sustainability is shaping more guest decisions, and reliable operational data is becoming more valuable.
In Booking.com's 2026 Travel & Sustainability Report, based on research with 32,500 travellers across 35 markets, 85% say more sustainable travel is important or very important to them(3). Booking.com also reports that in 2025, travellers booked more than 100 million room nights on its platform at properties holding a third-party sustainability certification(3).
Radisson reports that its first two Verified Net Zero hotels, in Manchester and Oslo, each register guest awareness scores above 70%, and that about 20% of guests indicate they booked because of the hotel's Net Zero status(2). These figures reflect Radisson's overall Verified Net Zero commitment, of which amenity collection is one part.
Cornell University's Hotel Sustainability Benchmarking Index 2025, published in March 2026 using 2023 data, introduced the benchmark's first waste index. Of 9,800 waste submissions, only about 4,500 passed validation for benchmarking(4). Dedicated, consistently recorded waste streams help close that gap at property level.
A Clearer Baseline for the Years Ahead
These records give Radisson Manchester an initial baseline for the bathroom amenity material it collects. Each new reporting period adds to its value. A record like this can help hotel teams:
- review collected quantities period by period
- share specific, factual information with owners, corporate clients and guests
- bring evidence to amenity purchasing and collection decisions
For fair comparisons, keep the same measurement boundaries each period and account for occupancy and collection timing. A lower collected weight alone does not mean less waste was generated. It may reflect fewer guests, a change in amenity format or when collections fall.
Across a group, property-level records can sit side by side, each read against the hotel's own size, occupancy and amenity choices. Combined with suitable treatment information and emission factors, the weights can also contribute to waste-related emissions calculations.

Bring Greater Visibility to Your Hotel's Amenity Waste
Clean the World works with hotels and groups across the UK and Europe to set up practical collection programs like Radisson Manchester's. Tell us about your property, and we will talk through suitability, collection arrangements, reporting needs and pricing.
Discuss Your Hotel's NeedsAbout the data: The weight is the gross weight of bathroom amenity material recorded for each collection received by Clean the World from the hotel, including any residual product in the bottles. It is a collected weight, not a recycled figure. The reporting period runs from the first to the most recent collection record date. The average per collection is calculated from the seven recorded weights.
