Municipal Solid Waste Treatment
Waste to Energy approaching Zero Landfill
IBC s.a.l.; a privately owned company, provides state-of-the-art integrated solutions for the most effective treatment of municipal mixed solid waste (MSW). IBC uses mechanical sorting and separation, and biological treatment (MBT) based on anaerobic digestion (AD).
IBC’s plant in Saida is currently capable of recovering up to 90% of the overall treated material. It produces biogas which it treats and uses to generate heat and electricity. The plant is of the waste to energy (W2E) type, rapidly approaching zero waste where no landfill is needed.
Recyclables: metals, glass, carton.
At IBC, recovered recyclables include: Cardboard, Plastic, Metals and Glass. These materials do not have high re-sale value, but their potential resides in availing economic opportunities for efficient downstream secondary industrial operations. Recovered cardboards, metals and glass are ultimately transferred respectively to paper mills, foundries and kilns.
Plastic on the other hand is sorted and separated into LDPE, HDPE, and PET then recycled internally to produce pellets for industry.
At IBC, we do not only re-cover resources. We preserve them and generate our own heat and electricity, and re-use our water thus making IBC a leading producer of renewable energy and resources. The anaerobic digestion of the organic fraction produces biogas and water leaving a partially stabilized wet organic mixture.
The biogas; a mixture of methane & carbon dioxide, is cleaned from potential pollutants such as hydrogen sulfide and impurities in compliance with the highest International emission standards. It is used to fuel CHP generators to produce heat and electricity while saving the planet from additional detrimental effects of methane & carbon dioxide, both greenhouse gases contributing the most to global warming.
IBC and RokyPlast jointly recycle waste plastic to produce LDPE and HDPE pellets and PET flakes ready for use by plastic processors as a prime raw material. The product is currently commercialized locally and exported abroad under the RokyPlast brand.
Soil Improver Amendment
The organic fraction remaining after the mechanical separation process is anaerobically treated in digesters. The resulting digestate is then stabilized, dewatered and sent for maturation. The resulting compost is used as a soil amendment to improve low quality soils.
The compost obtained from waste treatment at IBC is odorless and close in specifications to that obtained from source segregated processes as a result of the intricate mechanical separation of recyclables.
Refuse derived fuel
Light rejects of mixed waste such as styrofoam, pieces of cardboards, mixed paper, and used textiles are separated and treated to produce a high calorific value fuel substitute; refuse derived fuel (RDF) used in cement and other heat intensive based industries.
The RDF currently produced at IBC contains about 15% moisture and an officially tested calorific value of 26 mega joule per Kg (MJ/Kg).
Silica compounds derived from the dense fraction of the waste are finely graded ceramic inert materials. These grits are used as backfill materials and sub-base in road construction as well as in mixes for concrete building products such as curb stones, sidewalk tiles, and hourdi blocks and slabs.
These products; when in addition they incorporate also IBC's light fraction, are lighter in weight, have improved thermal and accoustic insulation properties, and enjoy higher tensile strength.
