Managing waste is the collection and ultimate disposal of the waste with minimal environmental impact. Every community in the world accumulates significant waste and has to deal with the problem of how to dispose it. The amount of municipal waste generated per person can vary from 0.5 up to 2.5 kilograms per day per person, depending on the country and level of affluence. This amount does not include hazardous waste, industrial waste and other types of waste that are not included in the definition of municipal waste.

Waste to Energy
CANITAN Engineering Group follows a systematic procedure for developing and evaluating technologies available to turn waste to energy (WTE).
CEG’s expertize is widespread and not limited to a single technology. We are therefore able to analyze each situation from an objective point of view.
Our goal is to promote the use of the best practicable technologies, implemented in an economically and environmentally sound manner.
CANITAN can provide the following services to support your selection of the proper technology for your application:
- Pre-Feasibility Studies: We perform and analyze your situation and provide a basic report on the options that are open to you and the best available technical solution. Significant saving in time, effort and cost can be realized by identifying potential risks.
- Project Feasibility Study: We can complete a feasibility study for your project, including analysis of both the technical and economic aspects of the project.
- Project Development Consultation: We can help you develop a project. We can help you identify and select the project team. We can help secure the financing. We can help negotiate power purchase agreements and waste supply contracts.
- Project Process Design: Working closely with you and the specifics of the waste stream to be processed and the desired energy production, CANITAN can develop the process design for your project.
- Turnkey Project: CANITAN functions as a project developer by determining the best technology for your given projects and working closely with the appropriate partners and affiliates for a turnkey project proposal.
WTE Training
CEG provides a number of custom tailored seminars to groups or individuals contemplating into adopting WTE:
- WTE 101—This course is designed for technical people to give an overview of all the technical issues that need to be evaluated in the selection of the appropriate technology for a project. We will provide detailed information about the history of the industry, potential applications, environmental impact, feasibility and major technology and equipment suppliers.
- WTE Technical Analysis—This seminar is designed for technical people who want to examine the technologies in a detailed manner. Attendees will explore design issues in all aspects of a project. This seminar can be customized to the specific project details and interests of the attendees.
- WTE Economic Overview—This seminar is designed to present a model for economic evaluation of a project for both financial and non-financial people to be able to evaluate the financial feasibility of a project. We identify the items for financial consideration in both the initial development of a project and it's ongoing operation and profitability.
- WTE Economic Analysis—This seminar is designed for the financial person who wants to look at detail financial models of the waste processing and energy generation plant. Best estimates for costs of construction and ongoing operational costs. Review of projected operating capital needs and cash flow projections.
- Capital Projects Funding—This seminar explores various options for funding a project in detail. Includes options for conventional financing and requirements. Methods for making the project more attractive to potential financing companies and non-debt financing options.
Soil Remediation
Remediation is the process of removing petroleum contaminants such as gasoline, kerosene and fuel oil from soil. CEG can provide field proven, suistainable technologies that support soil and groundwater remediation applications. Chemical oxidation (ISCO), Chemical reduction and bioremediation technologies are effective and cost effective for removal of wide range of organic compounds and heavy metals.
CEG provides remedial solutions that are more efficient, cost-effective and environmentally sound. Our technologies deliver best results for:
- Chlorinated Organics
- Heavy metals
- Petroleum Hydrocarbons
- PAHs
- Pesticides
- VOCs
Thermal Remediation Process
With most VOCs, the recommended target temperature is 100°C (i.e., boiling point of water at ambient elevation/pressure). As the site is heated, the vapor pressures and Henry’s Law Constants of the various VOC constituents increase. Therefore, as the temperature is increased, VOCs will readily enter the gas phase, enabling their removal by vapor extraction and/or multiphase extraction.
Of all the contaminant property changes that occur during heating, the increase in vapor pressure is the most dramatic. Vapor pressures of TCE and PCE, for example, increase exponentially during heating from ambient temperature to the boiling point of water.
- Advantages of in-situ Thermal Remediation:
- Effectiveness - Can reach very high remedial objectives, 99.99% removal.
- Effective on VOCs, BTEX, CVOCs, SVOCs.
- Works in Saturated & Unsaturated Zones.
- Rapid - Remedial goals reached in a short period of time - months not years
- Proven Technology
- Can be used when excavation is not an option.
With Excavation Option (Ex-Situ Soil Remediation)
In this case the soil is heated un in a rotating drum. The released gases, including hydrocarbons from the soil, are sent to an air pollution control device (thermal oxidizer). These devices heat the gases to extremely high temperatures in order to decompose them, destroying hazardous air pollutants, breaking down hydrocarbon-based pollutants and restoring the chemical makeup of the gas to CO2 and H2O before discharging it. The afterburners usually operates at a minimum temperature of 750 C and destroys more than 99 percent of the released hydrocarbons. The soil is then returned to its original place. This process is much faster than in-situ, but excavation and transport costs must be considered.
