R & D

Nature & Scope of Research & Development

Research is a series of activities to discover a new product or new process method.
Development is a series of studies to ensure the effectiveness of a new product or new process methods become a reality.

Research and development has particular significance, because the future of all products of companies will have the efficiency and high competitiveness, and thus of the company’s business objectives can be achieved.

Scope of research and development from a company include: Create and develop new products or new processing methods. It acts as a center of information for any other work units.

Purpose of research and development is the realization of a quality system that starts from the emergence of a new product idea to discover a new process or method of efficiently and effectively what would later be issued by the company’s product has efficiency and high competitiveness, thus the profit objectives of the business can be achieved.

Research and Development team mainly focuses on preparation of waste mix which can be used as a raw material or as a fuel in cement kilns. Apart from blend preparation, R&D team decides on factors like handling, storage, preprocessing and other management strategies associated with industrial hazardous wastes. As special cases, certain non-hazardous industrial wastes are also considered for blend mix after analysis.

R & D Infrastructure

GEPIL has its own fully equipped R & D centre since its establishment. R & D infrastructure was enhanced in accordance to the requirements of AFRF on its establishment. The centre is working on disposal of various hazardous waste, wastewater and AFRF.

R & D centre is equipped with following:

  • Pilot vessel for liquid blending
  • Sigma mixer for semisolid blending
  • Jaw Crusher and pulveriser for sample preparation
  • AAS and TOC
  • Hach spectrophotometer
  • Karl Fischer for moisture contents
  • Viscometer
  • Bomb calorimeter
  • Test kits and ion detectors
  • Motar Mixture

Recipe Preparation & Compatibility

The purpose of recipe preparation was to derive waste mixes having optimum characteristics which are acceptable to cement industries. Recipe preparation is the heart of AFRF operations. The utility of each and every waste received is subjected to its recipe prepared. Recipe preparation is initiated by the functional group composition of the waste and checking its reactivity and incompatibility with the other waste it is being mixed. The functional group incompatibilities are concluded from the compatibility chart shown below:

Compatibility of Hazardous Wastes

Furthermore, if the other chemical composition of the waste is also known then its compatibilities and incompatibilities are derived using CRW (chemical reactivity worksheet) software. Using this software, we can predict the potential chemical and health hazard of any particular waste on its reaction with any other waste, provided its composition is known.

Effect of hazardous waste on HDPE Liner and Liquid storage tank

Following applications are made to check the HDPE liner for its usage and effect of various hazardous wastes.

  • Check Durability and long-term integrity using various type of waste.
  • Effect on welding and attachment
  • Check stability during construction
  • Corrosion rate of MS material
  • Thickness test of MS material

Solidification & Stabilization

Heavy Metal bearing waste usually needs solidification/stabilization (S/S) prior to landfill to lower the leaching rate. Solidification/stabilization is accepted as a well-established disposal technique for hazardous waste. As a result many different types of hazardous wastes are treated with different binders. The S/S products have different properties from waste and binders individually. The effectiveness of S/S process is studied by physical, chemical and micro structural methods. The selection of binders and operating parameter depends upon an understanding of chemistry of the system.

Leachate Management

Leachate is the liquid that drains or ‘leaches’ from a landfill; it varies widely in composition regarding the age of the landfill and the type of waste that it contains. It usually contains both dissolved and suspended material. In fact the term “Leachate” is so often applied to landfill leachate, both within the waste management industry and outside, that it is easy to forget that leachate is the term used for any liquid produced by the action of “leaching” which occurs when water percolates through any permeable material.

  • Prepare a model of landfill cell
  • Leachate generation rate
  • Characteristic of Leachate
  • Effect on Leachate quality with time.
  • Decontamination and reuse of Leachate

R & D on Wastewater recycling

  • Optimizing the efficiency and cost of biological treatment processes and developing integrated wastewater management solutions preserving the natural Environment and fresh water resources;
  • Designing tomorrow’s wastewater treatment system, based on the systematic recovery of all wastewater and sludge components: reusable water, organic material convertible into bio energy and biomaterials, mineral materials transformable into fertilizers
  • Anticipating risk management with regard to future environmental and health issues.

Treatability study of various effluents

Treatability studies can be useful for water and wastewater. These studies involve coagulation-flocculation jar tests to determine the effectiveness of chemical treatment, coagulation, and flocculation processes for the removal of heavy metals and sludge. Effluents generated by the jar tests are analyzed for metals using ICPMS, ICP, and/or Cold Vapor AA and general chemistry parameters to determine the chemical composition of the effluent and the effectiveness of the treatment process.

Treatability studies and large analytical projects: These regulations require labs performing treatability studies to follow certain procedures when accepting hazardous waste for study.

  • Identification and listing of wastes to be regulated as hazardous
  • Tracking of wastes from the point of generation, through transportation, to the site of final treatment, storage, or disposal
  • Controlling the management practices used during the treatment, storage, and ultimate disposition of these wastes through technical standards, performance standards, and permitting requirements
  • Performing wastewater treatability studies at our specialized laboratory facilities for client-specific waste streams using various leading treatment technologies

Asbestos containing waste management

Asbestos has a number of uses in building construction, mainly insulation and can be found in lagging and fire retardant materials. Improper usage of asbestos has deadly consequences including various types of cancer. The mineral exists in very thin fibres and it disseminates in the air with ease – this is what makes asbestos removal a necessity.

Main concern at the site is Safe removal of Asbestos, PCB bearing materials and other harmful materials such as

  • Paint chips
  • Asbestos bearing wastes
  • Glass wool
  • Materials Contaminated with oil and chemicals
  • Oily sludge
  • Contaminated and corroded scraps
  • Other heavy metal bearing wastes
