Waste not, want not
International launch for the latest energy-saving waste management system from innovator Deerberg Systems.
following its official launch at the Shipbuilding Machinery and Marine Technology trade event in September 2008. Te “intelligent combined system for drying
D
solid and liquid wastes”, such as food waste, oils and sludges, was presented at the first SMM Istanbul event, a spin-off of the main SMM show, taking place between 21-23 January, 2009. Te system uses the waste heat from the ship’s waste incineration process as its return energy source. Jochen Deerberg, owner and chief executive
of Deerberg-Systems, said: “Tis is not about green image; it is about responsibility for the environment.”
Evac brings quiet relief
Helsinki-based Evac Oy, which supplies around 75% of toilets onboard cruiseship newbuildings worldwide, has developed a new, low noise vacuum toilet for cruiseships, in the shape of the Evac 910.. A new patented ‘quick relief’ valve cuts discharge noise by around 4dB(A) and peak noise by approximately 8dB(A),
when compared to the previous generation vacuum toilets. Recent testing carried out by an independent research centre has demonstrated that the sound level of the Evac 910 is around 5-8dB(A) lower than other vacuum toilets on the market. According to Markus Peltola, Evac director, European sales: “The Evac 910 is now clearly the quietest vacuum
toilet available to marine customers, with a sound level comparable to gravity toilets. With this toilet a major source of annoyance to passengers has been eliminated, and we are sure this will make a big difference to their enjoyment of the onboard experience.”

eerberg Systems GmbH is taking its latest integrated dryer for food, wet waste and biosludge to a wider market,
Advanced waste water treatment plants have
been introduced on a growing number of vessels over recent years, but their initial interface with the waste consisted of a decanter separating solids from liquids by adding a polymer to the waste water stream, and a stream-heated dryer to dry the bio-waste before it was fed into the incinerator. Such dryers have tended to consume extra energy, and thus generate additional emissions. Deerberg’s new integrated bio-waste dryer,
which is installed outside the incinerator, uses energy recovered from the incineration process itself. A part of the ‘off-gas’ caused by the incineration of burnable waste or sludge oil is directed into the dryer, in order to dry the bio-waste. Where the off-gas stream has an initial temperature of 350o
C, this is reduced to 250o C before entering the dryer, in order to
prevent extreme heat loads. A cruiseship carrying 5500 passengers would
demand two 2400kW incinerators and a total of four integrated dryers, to ensure full redundancy. In this configuration, with no diesel oil or steam production, the Deerberg solution would save up to 619tonnes of diesel oil per year when compared to forerunner systems. Tis, in turn, saves 7652tonnes in terms of CO2
emissions. Te SMM Istanbul overseas launch was part
of an initiative to encourage Turkish shipyards engaged in the superyacht sector to engage with the green agenda. Deerberg said that SMM Istanbul was “not a bad place” to launch the initiative, in view of the changes in regulations for waste water processing in superyachts from 2010 onwards. NA
