EDESSA routinely assists clients with regulatory compliance and environmental management. We consult with top management on strategic planning for environmental policies and programs as well as project developers and plant managers on site-specific environmental needs.

EDESSA helps clients develop and implement strategies for addressing regulatory needs, business opportunities and community concerns as well as ISO 14001 certification as desired. A key element in EDESSA’s approach to environmental management is the use of environmental audits and EIAs used to identify areas with environmental impairment and to assess regulatory compliance needs.

Pollution Control Engineering

The company’s experience encompasses all aspects of pollution control engineering for waste management, wastewater management and air emissions. These range from process engineering, emission minimization and recycling to the design and implementation of protection/remediation programs for air, soil, surface water and groundwater resources. EDESSA offers its pollution control engineering services to a wide range of industries, municipalities and waste management contractors. Our capabilities are strengthened by the various association agreements we have with specialized international consulting firms. Our projects often start with the evaluation of flows and loads and field and laboratory investigations. All process designs are computer-based. Process flowsheets are initially developed and then translated into outline Process and Instrumentation and Diagrams (PIDs). The PIDs are then developed into detailed drawings for all process units, piping and controls.

Waste Management

EDESSA provides integrated waste management, engineering, design, environmental and regulatory support services for the proper management of waste. Whether the need is developing a new waste management facility or bringing an older facility into compliance, there is no substitute to the creative solutions that result from expert engineering, design and construction support services. Waste management projects include all aspects of the sector from waste characterization and quantification to sorting, recycling, reuse studies as well as full-scale treatment using various methods such as composting, bioremediation, physical and chemical treatment of special wastes.

Landfill Engineering

Design of new landfills typically starts with the evaluation of the site and its assessment from a geological and hydrogeological point of view. Environmental impact assessments are then typically conducted. The design of a new facility typically includes extensive earthworks aspects. The lining system is adopted based on the results of the EIA and the GWIA, the type of waste deposited and the availability of mineral or geosynthetic lining materials. Specifications are developed for all components of the lining and the leachate collection systems. Operation plans are often prepared along with environmental monitoring plans. The management and treatment of leachate and gas are typically addressed in the operation plan of the site.

Dump Site Remediation

Waste is unfortunately not always disposed of in engineered landfills. The staff of EDESSA has been involved in the assessment and remediation evaluation of numerous such dumps. Typical activities related to existing dump sites include the improvement of the prevailing situation until the site can be closed. The next stage is to conduct a historical assessment of the facility in order to know how long the site has been in use and what type of waste is likely to be found in it. Field investigations are typically started following the initial stage. Proper closure of the site is usually the next priority. Remedial investigations and recommendations are then proposed for such sites based on the master plan of the area, the site constraints and the financial budgets available.
