The Stadtservice's 15 sweepers, three of which are now electric, are emptied15 times a day during the leaf collection period in October.

Normally, the sweepers only travel to the depot in Daimlerstrasse two or three times a working day to unload the leaves, but in October they are virtually in constant use. In order to increase efficiency, Stadtservice sets up four containers in the city area to enable unloading over short distances during the leaf season. All the green waste from the green spaces is sent to composting plants in the region with which Stadtservice works. There, the biomass is transformed into valuable topsoil within three to four years. Anyone who drops off leaves from their own property at the recycling center (up to one cubic meter per week is accepted there free of charge) is also participating in this sustainable circular economy.

GBO generated2.27 million euros from Stadtwerke's Geschäftsfeld Immobilien in 2021. This amount will not be transferred to general use within Stadtwerke Offenbach, but will be used specifically for the people of Offenbach - and thus for social sustainability: The money will flow into the construction of new affordable apartments, it will keep the number of publicly subsidized apartments at GBO constant until at least 2028 and will be used for renovations.

The future-oriented approach is also evident in the area of refurbishment: since 2006, GBO has refurbished 1,398 apartments to make them more energy-efficient, which is good for the environment as well as the tenants' wallets. As part of the construction measures, these properties were fitted with thermally insulated front doors, new and in some cases soundproofed windows, façade insulation and roof and basement insulation.

As the IMWF announced at the beginning of June 2022, only six other municipal utilities in Germany have been awarded the sustainability seal two years in a row.

Stadtwerke Offenbach sold35,300 9-euro tickets between June and August 2022. These are sales at advance booking offices and buses in Offenbach. It does not include season ticket holders, season ticket users and job tickets, etc., which were reduced to 9 euros.

The ticket, which is valid for one month at a time, was part of the relief package in the summer due to rising energy prices in Germany. It was valid on local buses operated by OVB Offenbacher Verkehrsbetriebe as well as on Deutsche Bahn's nationwide public transport network. According to the Association of German Transport Companies (VDV), the ticket was sold a total of 52 million times within three months.

18 kilometers of bicycle-friendly roads were created in and around Offenbach between the end of 2018 and mid-2022 on behalf of the city under the project management of Stadtwerke Offenbach. 9 km of cycle lanes and a further 9 km along six axes such as Senefelderstraße and Seligenstädter Straße now enable safe and fast connections. The cycle lanes are free for residents - i.e. no through traffic is permitted - and a maximum speed limit of 30 km/h for everyone, and cyclists are allowed to ride side by side. The new cycle lanes along Sprendlinger Landstrasse do not count towards the number of kilometers, as this is a Hessen Mobil project.

The project, which was funded by the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) and has now been implemented, is part of the city of Offenbach's strategy to promote environmentally and climate-friendly mobility. OPG Offenbacher Projektentwicklungsgesellschaft mbH was commissioned with the project management.

390,016.36 euros flowed into donations & sponsoring at Stadtwerke Offenbach 2021. A wide variety of areas of public life were supported - sporting and social, ecological and cultural.

In addition to Offenbacher Kickers as one of the largest sponsors, Stadtwerke also traditionally supports sports clubs that are particularly committed to local social causes: the nationally renowned Boxclub Nordend e.V., the national league judo club JC Samurai Offenbach and the Offenbach Fencing Club, with which a new three-year contract will be concluded on July 1, 2022. "The youth departments of these clubs contribute a great deal to integration in our international city," says Stadtwerke Managing Director Peter Walther. "Overall, our donations and sponsoring activities show that we care about the common good of our citizens far beyond the provision of services of general interest." In 2021, donations were made to the Bürgerstiftung and the Tafel Offenbach food bank as well as the Förderverein Sicheres Offenbach, TSG Bürgel and the Joblinge program, which helps unemployed young people enter the world of work.

The Klingspor Museum and the Capitol Classic Lounge have benefited from Stadtwerke's commitment for many years. The Mainbogen sheep farm, which ensures ecological landscape conservation in Offenbach, is also supported. In 2022, the jersey advertising for the youth of TSV Mühlheim Lämmerspiel will be added. The major events always supported by Stadtwerke Offenbach, the Mainuferfest and Lichterfest, are now also being supported again after a two-year pandemic break. There are also many opportunities for individual donations, ranging from grants for a play or sports camp to the Green Classroom and events against racism.

There are currently100 habitat trees in Offenbach's municipal cemeteries. The resting places, for which Stadtwerke Offenbach's Stadtservice is responsible, thus provide valuable habitats for many species, some of which are rare.

The tree population at the Old Cemetery makes a particular contribution to ecological diversity in the city: There are 71 habitat trees here alone - aged specimens with animal habitats in caves, crevices and niches, to which Stadtservice also attaches particular importance in terms of maintenance. As a study commissioned by the Office for the Environment, Energy and Climate Protection in 2021 showed, these trees are home to endangered deadwood beetles such as the longhorned beetle. There are also strictly protected bat species such as the lesser and greater noctule and numerous bird species, such as the redstart, which is highly endangered in Hesse, as well as the goldfinch, goldfinch and pied flycatcher.

Visitors to the cemetery can recognize the habitat trees in the Old Cemetery by the beautifully designed plaques with woodpecker and bat, while in the New Cemetery they are identified by numbered plaques. Overall, the Stadtservice of the Stadtwerke is committed to increasing biodiversity on its grounds: This spring, it planted three special bee meadows in the cemeteries in the city districts, and an educational trail on the subject of biodiversity has its first stations at the New Cemetery.

15 construction projects made of or with wood have been planned and largely completed by Stadtwerke Offenbach's Geschäftsfeld Immobilien in recent years.

OPG Offenbacher Projektentwicklungsgesellschaft mbH has so far used this sustainable building material in ten schools and daycare centers. These include complete timber buildings that have already been constructed, such as Kita 3 in Rödernstrasse (3), Kita 11 in Brandenburger Strasse and the new extension to the Albert Schweitzer School: their supporting structures are made of timber, as are the façades and walls, ceilings and roofs. In other new buildings, such as the Humboldt and Ernst Reuter schools, wood was used as a supporting structure and for the interior fittings, and the building material is also used for the front façades of daycare centers.

In recent years, GBO Gemeinnützige Baugesellschaft Offenbach mbH has built five apartment buildings with a total of 72 apartments in timber hybrid construction. The extensive use of wood as a sustainable building material, including in the floors, ensures a particularly good living climate. The modular construction method also means that the properties can be completed more quickly. The first new building of this kind in Taunusstrasse received an architecture award for "Exemplary Buildings in the State of Hesse" in 2017.

In addition to its ecological qualities, the flexibility of wood as a renewable, organic building material also speaks for itself: its colors, shapes and degrees of hardness offer countless variations for the architectural design of a building and its surfaces, both inside and out. The natural material is very durable and traces of use in the wood have less of a detrimental effect. Even if the building is to be dismantled, wood produces only a few pollutants thanks to its coatings.

152.38 tons of_CO2are saved by the ten LED stepped lens spotlights that have recently been used to illuminate the Capitol and Stadthalle stages compared to conventional light sources. They each have a service life of 50,000 hours, whereas conventional lighting consists of 2,500 lamps each lasting just 200 hours over the same period.

On the recommendation of the in-house sustainability consultant, the new LED floodlights were purchased at the end of 2021 for Stadtwerke Offenbach's Geschäftsfeld Veranstaltungen. The savings calculation is based on the Federal Environment Agency's estimate of around 401 grams of CO2 per kilowatt hour (kWh).

"We are gradually converting more and more light sources in our various fields of work to LED technology," reports Peter Walther, Managing Director of Stadtwerke Offenbach. The lighting at Stadtservice, for example, has already been largely converted to LED. "This allows us to reduce environmentally harmful greenhouse gases, and the much longer running times also save us operating costs in the medium term." The Capitol and Stadthalle team even made a "fair commitment" in 2020 and issued a declaration of support for the German-speaking event industry's sustainability code of the same name. The adjoining rooms and corridors of the event venues have long been lit by LED lighting, and the in-house catering at the Capitol has been largely plastic-free since 2010.

Customers cycled36,772 kilometers with the eMobil pedelecs in 2021. After registering once, anyone interested can rent a total of 20 electric bikes - and six electric cars - at six stations for effortless, environmentally friendly electric cycling in and around Offenbach. The stations are located at the town hall, at Nordring/Hafen, at Ostendplatz in Bieber, at Kurhessenplatz in Rumpenheim, in Tempelsee and in the An den Eichen residential area. At the start of the 2022 cycling season, for example, the new cycle lane along Sprendlinger Landstraße to Neu-Isenburg can be experienced safely and comfortably on e-bikes.

The service is operated by OVB (Offenbacher Verkehrs-Betriebe GmbH) from Stadtwerke Offenbach's Geschäftsfeld Mobilität and RMV (Rhein-Main-Verkehrsverbund) and is an important addition to the S-Bahn and city buses.

129 trainees have been given career prospects at Stadtwerke Offenbach since 2011. The company currently employs 42 trainees in various year groups. "Social sustainability means, among other things, the company's general responsibility towards society - we are happy to take on this responsibility by training far more than we need ourselves for many years," says Stadtwerke Managing Director Peter Walther. The number of trainees is rising continuously: in 2011, there were "only" 14 trainees in six professions. Today, Stadtwerke Offenbach offers young people a total of 15 apprenticeships and three dual study programs. The other offers for trainees also underline the social sustainability: Stadtwerke Offenbach covers all training costs, offers an RMV-wide job ticket and provides local support in finding accommodation. A number of trainee positions have also been advertised for 2022:

4,136.38 tons of organic waste was collected in Offenbach by Stadtwerke Offenbach's Stadtservice from January to November 2021. This waste is full of energy and can be processed into high-quality compost and biogas. This helps to secure our energy supply in the long term - and conserve valuable resources at the same time. The organic waste from Offenbach is converted into green electricity and heat in biogas plants - replacing fossil,_CO2-emitting energy sources such as coal and natural gas. This sustainable energy generation is also the reason why Stadtservice does not want to talk about "waste" in this context.

On average, 18 tons of organic waste can cover the annual electricity requirements of a four-person family of 3,500 kWh. With the energy from one kilo of biowaste, a television (80 W) runs for around 1 ¾ hours. Good quality biowaste is important for this sustainable recycling - it should therefore be separated properly and collected with as little foreign matter as possible. Biodegradable plastic bags are not permitted for biowaste in Offenbach because the plants cannot recycle them without residue.

In 2020, the Stadtservice vehicles cleaned47,540 kilometers of roads in Offenbach. In terms of distance, they drove 1.2 times around the earth - the equator covers around 40,000 kilometers. Since March 2021, two electric sweepers have also been in use, especially in the city center. According to the manufacturer, each of these machines saves a good 80 kilograms of_CO2every day compared to a diesel machine.

This not only benefits the environment: every vehicle that is emission-free and silent on the road in Offenbach contributes to a better quality of life for us all. Street cleaning also includes the winter service, whose fleet is always ready to go at this time of year.

598,270 kilometers have been driven by the e-buses in Offenbach since commissioning up to and including mid-October 2021. This corresponds to a_{CO2 saving of} around 806 tons.

Stadtwerke Offenbach put the first electric buses on the road at the end of 2020. There are currently 24 electrically powered buses ensuring better air quality in the city; by the end of 2021, there will be 36.
