Landfill
RE- The Landfill Directive Implementation from 16th
July 2004
As from the 16th July 2004, our company operates an IPPC
permitted Landfill site for non-hazardous wastes with cells
for stable non-reactive hazardous wastes. This means that
we can receive all non hazardous industrial/commercial waste
streams into our Seaton Meadows Landfill.
We can also take into our stable non-reactive hazardous
waste cell, the following;
1) Bonded asbestos
2) Fibrous asbestos
3) Contaminated land*
4) Any other stable non-reactive waste (hazardous) *
* See Waste Acceptance Criteria table re: Leachability
testing.
Waste Characterisation / Compatibility
The landfill Directive required that all procedures of
hazardous waste must provide an analytical assessment of
the waste to confirm if the waste is compatible with our
waste acceptance criteria (see table) for our Stable Non
Reactive Hazardous Waste cell.
We would urge all customers to have this analysis undertaken
as soon as possible.
Re-Classification of Waste
It has come to our attention that many current waste streams
are being consigned as “hazardous waste” but
are infact not hazardous.
Typical examples are empty paint tins and contaminated
packaging or rubbish. (See included table).
Thresholds for irritants, harmful toxic materials etc
can be shown in the table.
Onus in the past has been placed on the materials used
by producers of wastes rather than determining the “hazard”
content of the waste itself.
For example, an empty dry used paint tin containing no
hazardous materials is not a hazardous waste.
Packaging with less than 10-25% of an irritant or harmful
material is also below the threshold of determining hazardous
waste, therefore producers should look at their individual
waste streams and house keeping regimes to see if any of
their waste can be re-classified as “non-hazardous”.
Pre-treatment of hazardous waste
Hazardous waste – not conforming to our Waste Acceptance
Criteria will have to be pre-treated prior to landfill.
We are in the process of building a treatment plant that
will handle both liquids and solids. This plant is expected
to be completed towards the end of 2004.
We trust the above information helps to clarify this particular
concern for our customers.
