TOI TOI & DIXI – the market leader
A story of success
1973
Fred Edwards founds Port San Ser in Essen/Germany, the first company for mobile sanitary systems in Germany and Europe – later DIXI®.
1980
Pope John Paul II visits Germany – our portable toilets are being used for the first time at professional events and are becoming world famous.
1983
DIXI® gets competition: Helga and Harald Müller found the company TOI TOI Sanitärsysteme in Wiesbaden/Germany.
1986
Unstoppable growth: international expansion for both DIXI® and TOI TOI® in Europe.
1989
The 11,111 portable toilet is delivered to DIXI®.
1997
We are world market leaders. The two sanitary service providers DIXI® and TOI TOI® merge to form the ADCO Group.
1999
Professional events without TOI TOI & DIXI have become unthinkable. Sanitation for World Youth Day visitors in Rome is provided by 5,000 portable toilets.
1999
Our own production commences at our Gerstungen location in Germany: our portable toilets are now being produced independently by our subsidiary HMT Kunststofftechnik. This makes us independent. The first product manufactured there is our TOI® Fresh portable toilet.
2000
We also become independent in vehicle construction. Our subsidiary HMT Fahrzeugtechnik launches its own production of state-of-the-art service vehicles at its Dohna location in Germany.
2001
Product innovations make us successful: launch of TOI® Water – the first portable toilet with a large wash basin with fresh water supply integrated into the side wall. The next novelty is the TOI® Flush – the world’ first portable toilet with automatic fresh water flush and a tank concealed from view.
2003
The largest public contract for TOI TOI & DIXI to date: during the “Castor transport” to Gorleben we provided accommodation and sanitation for 15,000 police officers with 1,250 multipurpose and sanitary containers.
2005
World Youth Days 2005 in Cologne: the demand for portable toilets is steadily increasing at professional events. With over 8,000 mobile portable toilets, we ensure that the sanitary needs of visitors are met.
2005
Mobile sanitation has also become indispensable in non-civilian and humanitarian environments. We found a task force for large-scale projects as a response to this need.
2005
As market leader, we are constantly working on new, innovative products: we introduce the new DIXI® Plus portable toilet, which offers more space and comes with certain extras.
2006
Our production location is growing steadily: HMT Fahrzeugtechnik relocates to Gerstungen/Germany. In addition to portable toilets, our own service vehicles are now also built here.
2006
Mega event: “FIFA World Cup 2006” in Germany. TOI TOI & DIXI provides more than 10,000 portable toilets. At the same time, we respond to the exacting demands in the VIP segment. By launching our Premium Line sanitary containers, we set new standards of exclusivity. We present 110 Premium Line units on the occasion of the soccer event.
2007
DIXI® is honored as “brand of the century” for the first time.
2008
We experience further growth and strengthen our market position: The “TOI New companies” of Austria, Switzerland, Poland, the Czech Republic, and Russia are incorporated into the ADCO Group.
2008
Our goal is to advance product innovation and development even faster: we establish an in-house design department.
2011
Pure luxury: we set new standards. With the launch of the TOI TOI® Superior Line sanitary container, we are introducing a new product that outperforms everything we’ve seen so far in the field of mobile sanitation.
2011
We provide the right solution for any professional event: during the Pope’s visit to Erfurt (Etzelsbach/Germany), we provide sanitation in the form of more than 1,560 portable toilets and 80 multipurpose and sanitary containers, in addition to responding to the need for mobile spaces in the backstage area.
2012
A new record: for the first time, more than 200,000 of our portable toilets are in use worldwide.
2013
Congratulations: we celebrate 40 years of DIXI® and 30 years of TOI TOI®.
2014
The perfect solution for every requirement: by launching the DIXI® Mini portable toilet, we are introducing a special portable toilet for structural and civil engineering purposes with an integrated removable tank.
2015
The turnover of the ADCO Group exceeds 300 million euros in sales for the first time.
2017
We introduce an innovative vacuum sanitary concept: John Privy® impresses festival- and event-visitors with a high level of comfort, state-of-the-art vacuum technology, and cool design.
2019
Innovationen vorantreiben: Mit der Einführung des autarken WC-Trailers TOI® now, bringen wir einen Toilettenwagen auf den Markt, der umweltfreundlich ist und dank neuester Technik komplett ohne Anschlüsse funktioniert.
2019
Driving innovation: by launching the self-contained TOI® now sanitary trailer, we are introducing a sanitary trailer that’s environmentally friendly and works entirely without any connections thanks to state-of-the-art technology.
2019
Apax Partners acquires majority stake in ADCO Group. Together with the existing shareholders, the long-term basis for further investment and growth is created.
2021
ADCO Umweltdienste Holding GmbH changes its name to TOI TOI & DIXI Group GmbH and will from now on present itself with a new name and logo together with its subsidiaries as one large group of companies.
