Activated Carbon is used in a wide range of phase applications. Adsorbents generally have a limited life time and need to be managed once they are saturated or the treatment objective is reached. Jacobi Services offers several disposal or recycling services in different facilities, depending on the processes in which they have been used..
Activated Carbon has a finite capacity for organic adsorption and has an almost unique characteristic in that what has been adsorbed is possible to remove by thermal treatment. Reactivation subjects the carbon to high temperature processing and simultaneously reduces the toxic adsorbate to basic inert compounds like water and carbon dioxide.
Spent granular (GAC) or pelletized extruded (EAC) activated carbon can be recycled by thermal reactivation, in which the spent carbon is processed through a high temperature reactivation furnace at or above 850°C. The adsorbed organics on the carbon are thermally decomposed. The resulting gases are fed through an afterburner and a treatment system to allow emission to atmosphere in accordance with most stringent environmental regulations. Recycling by thermal reactivation is an environmentally responsible disposal method that helps to reduce CO2 emissions over the activated carbon and contributes to a sustainable use of the world’s resources.
As an environmentally responsible company, Jacobi has invested in facilities that will regenerate spent activated carbon. Our plants in Europe are strategically located to serve the Western and Eastern European activated carbon users to minimise transportation costs and time.
Our facilities are located in:
– Jacobi Carbons Services (Europe) GmbH, Premnitz, Germany
– Jacobi Carbons SASU, Vierzon, France
– Recently opened: our newest reactivation centre in Catalayud, close to Zaragoza, Spain
With over 12,000 MT of annual capacity, including the ability to perform custom reactivation for potable, food and industrial grade spent carbons, the Jacobi Carbons reactivation plants provide an effective option to media replacement.
Through all facilities, reactivated carbons that are produced through this process are available for sale under our ReSorb brand:
ReSorb™ SC: granular carbon specifically designed for the adsorption of low molecular weight organic compounds from liquid phase.
ReSorb™ HC: granular carbon specifically designed for the adsorption of higher molecular weight organic compounds from liquid phase.
ReSorb™ VT: coarse activated carbon specifically designed for the adsorption of volatile organic compounds from gas phase.
ReSorb™ Solo: Dedicated reactivation and return of our clients’ spent activated carbons. Reactivation is done according to individual specifications agreed with our clients, including the addition of virgin activated carbon to make good losses incurred during removal and processing of the spent material.
Recycling & Disposal
Where reactivation is not an option for spent activation, the skills provided within Jacobi can assist to develop an ecologically sensitive, yet cost effective, method of managing the end-of-life processing of the media.
In a limited number of exceptional cases, the condition of the spent activated carbon means that it is not possible to undertake reactivation. This may be as a result of the chemicals specifically adsorbed onto the carbon itself (such as mercury, sulphur or other toxic compounds) or as a result of the accumulation of other substances present in the water or gas being treated (for example minerals like calcium (Ca) and aluminium (Al) from upstream treatment steps).
Where feasible it may be possible the spent activated carbon may be blended to a less demanding waste form and here the reactivation may be possible. Products are then recovered as part of our ResorbTM range of carbons for industrial use. Nevertheless, some spent activated carbons must be considered as a waste stream.
In these cases, Jacobi Services provide alternative solutions. We conduct a full assessment of the material and consign it to an appropriate waste management facility, in line with regional and national regulations. These partners will use the spent carbon either as a waste derived fuel (WDF) for the processing of minerals or manage the material to a destruction facility. In this case, often the heat generated is used to generate steam or electricity for district heating and power companies respectively.
