THE WASTE MANAGEMENT: A WORLD ENVIROMENTAL PROBLEM

The problem of Waste Management affects all countries around the world, and with increasing population, the problem of waste management increases exponentially. 

Each country chooses different systems to solve this problem: collection of waste to recycling materials, disposal on landfills, incineration,  but until today, without effective results. 

Many countries in the world have significantly increases the necessity to observe methods of recycling and reuse materials reclaimed from MSW and other waste. But recycling and energy recovery is only about a fourth of the total MSW and other waste; the remaining three-fourths is  disposed  in landfills or incinerated (burned). 

These traditional methods of waste disposal are increasingly becoming less viable. In some countries, where there is limited landfill space, or where new laws and regulations do not allows disposal of MSW in landfills or fees requested to disposal waste on landfill are very expensive,  the traditional disposal methods of  landfilling and incineration are becoming less feasible.

In addition to consuming valuable land, decomposing MSW generates methane, a greenhouse gas, and the leaching wastes may also pose a threat to surface water and groundwater. Further, some areas have banned incineration of waste because of the negative environmental impacts.
We think  it's necessary resign old waste management systems environmentally dangerous such as:

LANDFILLING

Oldest method, for waste disposal in landfills. Waste digested anaerobically  and produce biogas used as source of heating or energy. 

INCINERATION 

Mass burn technology in presence of oxygen. Waste burn in incinerations and is converted into ash and harmful greenhouse gases.

PYROLYSIS

Thermal treatment in absence of oxygen at low temperature.
Syngas, pyrolysis liquid and coke obtained as products.

WASTE PLASMA GASIFICATION SOLUTIONS

Faced with the costly problem of waste disposal and the need of more energy in the World, many countries are turning their attention to Waste Plasma Gasification Technology, a time-tested and environmentally-sound; it's the best technology to convert the waste into useful products such as electricity, fertilizers, transportation fuels and chemicals. On average, conventional waste-to-energy plants that use mass-burn incineration can convert one ton of MSW to about 550 kilowatt-hours of electricity.

With waste plasma gasification technology, one ton of MSW can be used to produce up to 1,000 kilowatt-hours of electricity, a much more efficient and cleaner way to utilize this source of energy. Waste Plasma Gasification can help the world to manage its waste and transfome (100% of waste) into energy products .

 




WHAT IS GASIFICATION

Gasification is a unique process that transforms a carbon-based material, such as MSW or biomass, into other forms of energy without actually burning it. Instead, gasification converts the solid and liquid waste materials into a gas through a chemical reaction. This reaction combines those carbon-based materials (known as feedstocks) with small amounts of air or oxygen (but not enough to burn the materials), breaking them down into simple molecules, primarily a mixture of carbon monoxide and hydrogen.

What’s produced is a synthesis gas (Syngas) that can be converted into electricity and valuable products. With gasification, MSW and wastes are no longer useless, but they become feedstocks for a gasifier. Instead of paying to dispose of and manage the waste for years in a landfill, using it as a feedstock for gasification reduces disposal costs and landfill space, and converts those wastes into valuable electricity, fuels, chemicals or fertilizers.

GASIFICATION IS USED WORLDWIDE

Gasification has been used worlwide on a commercial scale for making "town gas" from coal for heating, lighting and cooking for over 200 years. Is has been used for more than 80 years by the chemical, refining and fertilizer industries and for more than 36 years bu the electric power industry.

It is currently playing an important role in meeting energy needs around the world, using a wide range of feedstocks that include coal, petroleum coke, and biomass. Gasification is now being adapted for smaller-scale applications to solve the problem of waste disposal and to extract valuable energy from waste. quote.

GASIFICATION CAN RECOVER VALUABLE ENERGY FROM WASTE 

  • In the gasification process, MSW is not a fuel, but a feedstock for a high chemical conversion process. There’s no burning.
  • Gasification can convert MSW that would typically be incinerated into a clean, useful syngas.
  • This clean syngas can then be used to produce energy and valuable products, such as chemicals, transportation fuels, fertilizers, and electricity.
  • Gasification does not compete with recycling; in fact, it enhances it. Metals, glass, and other materials that cannot be gasified are typically segregated from the waste stream prior to being sent into the gasification process. In addition, many plastics in MSW cannot be recycled and would otherwise end up in a landfill. Those plastics make excellent high energy feedstocks for gasification, thereby reducing the amount of those unrecyclable materials that would otherwise end up in a landfill.
  • There are significant environmental benefits of MSW gasification, including reducing the need for landfill space, decreasing methane  emis- sions from the decomposition of organic materials in the landfill, and reducing the risk of surface water and groundwater contamination from landfills.
