2. Waste Analysis and Characterization Study
This presentation is prepared mainly for the purpose
of development of Material Resource and Energy
Facility (MREF) and Waste-to-energy (WTE) facility
using Municipal Solid Waste as feedstock. The result
of the WACS will be the basis for the conduct of the
Preliminary Engineering Design Study (PEDS) to
determine the capacity of a proposed MREF or WTE
facility.
The accuracy of the WACS is very important in the
design of the proposed facility.

3. Waste Analysis and Characterization Study
 Data quality objectives.
 Determination of a representative sample.
 Statistical methods to be employed in the analyses.
 Waste generation and handling processes.
 Constituents/parameters to be sampled.
 Physical and chemical properties of the waste.
 Accessibility of the unit.
 Sampling equipment, methods, and sample containers.
 Quality assurance and quality control (e.g., sample
preservation and handling requirements).
 Chain-of-custody.
 Health and safety of employees.

4. Why do WACS?
Waste characterization is comprised
of a waste stream composition
profile by material types (i.e. paper,
plastic, etc.) and corresponding solid
waste weight estimates that can be
used to evaluate the current solid
waste management system and
assist in determining future program
waste diversion and conversion
process.
It is necessary to recharacterize
waste in order to accurately make
waste management decisions and
evaluate environmental risk.

5. The WACS for the Waste-to-Energy Facility Project,
why it is necessary.
Knowing the physical and chemical properties of a waste
using sampling and analysis techniques is the cornerstone
upon which subsequent steps in the waste management are
planned.
It is necessary for gauging what is the design capacity and
a waste might pose to surface water, ground water, and air
and drives waste management unit design and operating
decisions.
Knowing the composition of the waste is also necessary when
determining the constituents for which to test. Knowledge of
the physical and chemical properties of the waste is crucial
in identifying pollution prevention opportunities.

12. Sampling and Analysis Plan
The sampling plan is usually a written document that
describes the objectives and details of the individual tasks
of a sampling effort and how they will be performed.
Background information on the processes that generate the
waste and the type and characteristics of the waste
management unit is essential for developing a sound
sampling plan. Knowledge of the unit location and
situation (e.g., geology, exposure of the waste to the
elements, local climatic conditions) will assist in determining
correct sample size and sampling method.
Sampling plan design will depend on whether the sampling
of waste prior to disposal in a waste management unit or
whether the sampling of waste is from an existing unit.
When obtaining samples from an existing unit, care should be
taken to avoid endangering the individuals collecting
the samples and to prevent damaging the unit

• For example, waste arising from a
small barangay may be split into
two waste areas: residential and
farms;
• Each of these ‘waste sources’ has

www.greenergyph.com

17. Sampling Process
Gather the necessary equipment to aid in the
waste sampling process.
Clear waste bags/boxes should be available at each ‘waste source’
to allow wastes to be collected. Pens and labels should also be
distributed to each ‘waste source’.
The ‘waste characterization area’ should contain a weighing scale
(with a range from 0 to 20kg, with accuracy to 0.1kgs)), several
containers for holding and sorting the waste, shovels, a brush, a
first aid kit, clipboard, labels, pens and worksheets. Several
copies of the ‘Waste Collection Area Worksheets’ should be on
hand for each day of the survey.
Health and safety issues should also be considered. All members of
the waste analysis team should wear protective clothing (such as
rubber gloves, heavy duty shoes, safety glasses and coveralls)
and precautions should be taken to ensure that the waste does
not come into contact with food or drink.
www.greenergyph.com

18. Conducting the Survey
Once these tasks have been addressed, the waste
characterization analysis survey may begin. At each
‘waste source’, two categories of waste will be
generated:
(a) Segregated waste streams – These waste streams
will be homogenous and consist of material of a single
type, for example cardboard, paper, plastic, food waste
etc.
(b) Mixed waste streams – These waste streams will be
heterogeneous in nature and consist of mixed waste of
various types. The characterization of this waste stream
is more difficult. www.greenergyph.com

23. Only representative samples of mixed waste
Methodology must be sorted and weighed.
• During the survey period randomly take samples
of mixed waste (>10kg) from each of the ‘waste
sources’.
• The number of samples, which are sorted and
characterized from each ‘waste source’, should
be representative of the total volume of waste
produced from each ‘waste source’.
• For example, if ten bags of mixed waste arise
from the offices of an organisation per day and
only two bags of mixed waste are produced
from the canteen then the sampling regime
should reflect this ratio.
• The greater the number of mixed waste samples
which are characterized, the more accurate the
results will be. Attempt to characterize as many
samples as time allows.

29. Moisture content determination
 After the sorting and weighing the
individual waste stream, secure the
samples in an area for the next ten (10)
for another weighing process to
determine the moisture content.
 Moisture content formula:
MC= weight (fresh waste)
weight (after drying for 10 days) x 100
