Municipal Solid Waste (MSW)
The plant performance is
related to the composition of feedstock input (calorific value and moisture
content). Average MSW content varies from country to country since there is the
difference in climate eating patterns, and initial sorting of waste.
Due to the built-in design features, the MPSC system successfully accommodates
sudden fluctuations in the waste quality from its average value, which occur
within the facility.
This pyrolysis system for treatment of MSW and other wastes
demonstrates excellent practical performance in controlling the emission of
harmful substances such as dioxins with levels dramatically lower than
regulation values. No special chemicals, which may have impact on the overall
environmental performance, are required for the process.
The MPSC plant does not produce waste water effluent from the gas cleaning
system. Along with this obvious environmental advantage it also makes the system
less expensive. Another environmental aspect is the reduction of the residuals.
Solids after the treatment at the facility can be used in the building industry.
Typically 100 tpd plant treating MSW with a calorific value of 8,4 MJ/kg and
moisture 40% (thermal energy from wastes ~ 9,72 MWh) the MPSC process generates
2 MW of electricity. Consequently the MPSC process will annually generate ~15,6
GW gross electrical output and ~11,7 GW of net electrical energy is supplied to
the grid (325 days operation per annum)
WPP SynEnergy System
WPP SynEnergy System Composting MBT front-end, to produce a high purity compost,
followed by a pyrolysis stage to cleanly convert any synthetics to electrical
energy. This results in an in-vessel MBT system that is energy self-sufficient
and exports a significant amount of clean electrical power.
use of pyrolysis to reduce the synthetic materials to a clean gas ensures that
any pollution is minimal and that dioxins and furans are not produced. The
conversion of biomass to compost and synthetics to energy, results in a facility
that provides high quality, organic-rich soil conditioner without the need for
external power and greatly increase WPP landfill diversion which can be as high
as 90%, dependent upon the waste stream.
MBT front-end ensures that recyclable materials can be cleanly recovered. The
WPP SynEnergy System is particularly suitable for areas of poor soil quality
where the true value of compost will be recognized and valued.
WE MANAGED TO CREATE A MIRACLE OUT
OF SCRAP TIRES
Solid wastes threaten human health as well as causing environmental pollution.
Developed countries fund research and development studies that aim to eliminate
solid wastes of environment and the most effective method is recycling since it
creates an additional economic value out of waste while cleaning the
Although solid waste reminds the concept of household garbage, in today's world
scrap tires are one of the most dangerous wastes that requires urgent
precautions to be taken against. Worn-out, damaged, old and defaulted tires are
classified as waste or scrap tires and are;
derivative and hard to extinguish when under fire),
High in volume (huge dimensions and stocking covers broad areas),
Poisonous (release poisonous gases while burning),
Scattered in environment (lack of specific gathering areas; left to garbage
dumps, road sides, gas stations, various kinds of empty territories)
And because of these reasons, scrap tires are dangerous wastes that need to be
paid attention to. The amount of scrap tires in many different countries are
expressed in millions of tons.
Scrap tires are;
Burned (to obtain thermal energy which is extremely poisonous),
Left to garbage dumps,
Used as barriers,
Grazed to be used as shoe-sole material (only exterior part of tire is grazed).
Those are the most common methods to evaluate scrap tires. But none of these are
capable of totally eliminating the scrap tire problem. Granulizing is the
process that diminishes the certain rubber-based parts of the tire into small
pieces but since the granulizing process does not compromise the whole tire,
considerable amount of tire is left as scrap, therefore
GRANULIZING IS NOT A RECYCLING
The evaluation methods listed above contribute to the reduction of the amount of
waste tires but can never be a long-term and permanent solution to waste tire
problem. This pessimistic picture caused environmental organizations,
universities, research institutions and private entrepreneurs like us to conduct
research and development studies over the recycling methods concerning scrap

different products (steam, gas, oil, etc.) are obtained. Phases of the process
are determined by the process temperature, pressure, duration, and the variety

optimum phase durations, temperatures, pressures, vacuum levels, amount of waste
