Qualification creation
In the qualification process, the generator delivers
samples to determine suitability and risk in the
alternate fuel stream. The creation process provides
a mechanism for organising and storing the extensive
data associated with requests for the pre-qualification
of waste streams. As samples are registered and
analysed, the link to analytical results is stored in
the laboratory module. The link follows both the
qualification and future stream throughout the lifecycle.
Qualification approval
Waste streams are diverse in source and content.
Qualification approval is a module that allows users
to register their approval decision on waste streams.
Waste streams are pre‑qualified to permit the
transportation of the bulk material. The qualification
approval is also integral to the invoice process; all
shipment manifests and invoices are linked to the
approval.
Laboratory module
The laboratory module is the core of the WFIMS
package. It eliminates the requirement for hand
copying and the multiple handling of sample
analysis results. The laboratory module integrates
with laboratory equipment to pull data directly into
the WFIMS. Automated result capture reduces
transcription cost and error. Reporting from the
laboratory module provides the ability to directly
compare sample analytical results and a defined
profile for a pre-qualified waste stream.
Waste tracking module
Sites that collect waste for the AFR process have a
hazardous material risk. The waste tracking module
(WTM) is an end-to-end method of recording
waste material transactions and logging inventory
location. Information is recorded throughout the
initial scheduling of incoming shipments, as well as
receiving, storage, and processing. New shipments
outbound to alternative waste handling facilities are
created and tracked.
Inventory management
The WTM supports the recording and tracking of bulk
shipments via tank inventory and individual containers
into storage. Material tracking is present throughout
the lifecycle, from inbound containers, batch sampling,
and transfer to fuels processing. The WTM includes
an inventory verification function that allows periodic
inventories of all containers in the storage and
reconciliation of records, based on inventory results
(Figure 1).
Data query and reporting
WFIMS Query is a tool that allows users to generate
ad-hoc reports that include Waste Material Profile
and analytical data from the laboratory module, along
with shipment data from the WTM. Analytical results
across all samples associated with a set of shipments
can easily be extracted and correlated.
Inventory scanner
A mobile application at the material point of entry
speeds up processing. Bar codes are widely used
to eliminate error. Most generators will track the
manifest detail and pre‑qualification directly into the
WFIMS.
Safety
The integration of the laboratory module, the WTM,
and the inventory scanner improve the data collection
and management associated with the analysis,
approval, handling, and processing of waste fuel
materials. Integrated reporting tools assist in the
analysis of constituents present in a waste stream, in
order to determine the safe sampling and handling of
waste at the receiving facility. The system categorises
waste material to produce a handling and storage
risk assessment based on the site’s specific safety
requirements.
