Recent decades brought a rapid growth in the global demand for energy. This trend is accurate for both developed as well as developing countries. Electrical power is a key source of energy for the vast majority of the world population. Although the usage of renewable energy is on the rise, the majority of electric power production worldwide is still based on conventional methods utilizing coal, oil and gas as its fuel to power the stations.
Landfills are categorized by regulations in three types: industrial, municipal, and hazardous. Individual landfills may be further differentiated by the types of waste which they accept. All landfills are required to be capped, usually occurring at the end of each day. The cap is typically 6-8” of soil. The cap reduces odor and loss due to wind. At the closing of the landfill, a permanent cap consisting of a membrane and more soil is added. Before the landfilling operation begins, an “impermeable”...
Biogas is increasingly important as source of sustainable energy. When biogas is produced through any form of anaerobic digestion, it will be mostly polluted with hydrogen sulphide. The concentrations can vary from 200 ppm up to several volume %.
Our range of gas monitoring instruments are used to measure the constituents of Biogas and monitor Landfill sites for Methane (CH4), Carbon dioxide (CO2), Hydrogen sulphide (H2S), Carbon Monoxide(CO) and Oxygen (O2).
Gradko’s ambient air monitoring equipment is widely used to monitor both indoor and outdoor air quality. Continuous development allows us to provide equipment for a broad range of applications, covering short-term and long-term monitoring. Pollutants can be detected even at very low levels – limits of detection are typically in the low parts per billion (ppb) range.
We have developed many flow meters and controllers to measure the emissions from landfills and other green house gas producers, in addition to being a long standing leader in the testing of emissions for large engines. Water treatment is also an important driver for the company as we continue to develop innovative solutions for waste water treatment.
Energy recovery from municipal waste is the conversion of non-recyclable waste materials into usable energy like heat, electricity, or fuel through a variety of processes, including combustion, gasification, pyrolization, anaerobic digestion and landfill gas recovery. This process is often called waste to energy by the industry.
The Applied Catalyst Activated Carbon Monolith (ACM) can be used for CO2 capture, H2S adsorption, and hydrocarbon adsorption. The porosity and high surface area of activated carbon is sufficient to allow for long-term capture and subsequent de-adsorption of various gases.
Throughout the world, green vegetative organic material like brush and leaves is buried in landfills whole or after being processed through grinders. This organic material takes up valuable landfill space which breaks down to biogas containing methane. If not captured, this potent greenhouse gas contributes to global warming.
State-of-the-art systems enabling easy monitoring of CO2 and CH4 gases. A landfill site is a site for the disposal of waste materials by burial. Historically, landfills have been the most common method of organised waste disposal and remain so in many places around the world. Some landfills are also used for waste management purposes, such as the temporary storage, consolidation, and transfer, or processing of waste materials. Landfill gas is created by the action of microorganisms within a landfill. This...
