Progress of Construction Works in April

Construction and installation of the Eddy Current separator took place in April as
described later in the report.

All other major construction works have now been completed and snagging lists have
been compiled to progress finer technical detailed points associated with the initial
construction works.

Plant Operations
Batches processed during April

A total of eight batches were processed during the month of April 2002 (Batch 014
charged on 2nd April to Batch 21 charged on 30th April).

Grass wastes and other biodegradable products were highly noticeable during the
month of April and certainly increased in volume as the month progressed.

Contractual matters with CPS

CPS submitted their invoice for the final 12.5% of the original contract value on the 3 rd
April 2002. At this stage we did not consider that the works were sufficiently complete
and therefore did not pass on the payment at this stage.

Work during the month however progressed as discussed through several meetings
between CPS and ourselves with many of the issues being resolved or partly
progressed, and it was considered that it would be unreasonable to withhold this
payment due to the above mentioned issues.

It was therefore decided to split this payment into three sections

   a) 4.0% Initial payment
   b) A further 4.0% on completion of class 1 items (Premier snagging list)
   c) The final 4.0% on completion of class 2 items (Premier snagging list)

CPS agreed to these conditions and submitted their invoice for part “A” of the above.

CPS also submitted their invoice for the 15% of variation order upon completion/erection
of the Eddy Current separator. This has now been paid.

Eddy-Current Separation

The power supply for the eddy current separator was fitted on Tuesday 2 nd April and the
Unit itself was delivered to site on Wednesday 3rd.

Installation of the equipment itself took place immediately following delivery and was
completed on Tuesday 9th April.

Commissioning of the unit took place over a number of days predominantly using the
discharge of batch number 13 to test the equipment.

This unit is now operational and is recovering Aluminium, Brass and Copper. There are
now adjustments we can make to improve the separation in order to obtain a higher
quality mixture of non-ferrous metals.


Waste Management Licence

The revised version of the site waste management license was finally issued on 25th
April and all operations at the site are now working to conditions set out in the license.

Newcastle University (Recycling to Land Department)

As described in the March report, additional chemical analysis has been conducted for

   a) PCB’s (Poly Chlorinated Bi-phenyl’s)
   b) PAH’s (Polycyclic Aromatic Hydrocarbons)
   c) Clostridium

The objective of the analysis initially was to build up a quick database of information on
these categories of chemical and biological compounds. The initial results of the
quantities of all of these compounds show that levels are well below or absent below
thresholds.

Independent Laboratory Analysis

In addition to the analysis conducted by the University and in an attempt to gain as much
information regarding the new set of chemical analysis as described in the March Report
(PCB’s, PAH’s and Clostridium), samples for analysis have been sent to external
accredited laboratories for chemical and biological analysis (see above).

Following a review of all the chemical and biological analysis a revised suite,
concentrating on the issues which are predominant, possibly in May or early June.

The revised suite of analysis will enable us to carry out multiple sampling of batches and
establish various conditions and stages of digestion throughout the process.

Health & Safety Matters

I am pleased to report that there were no issues related to health and safety matters
during the month of April 2002.

There is still no feedback from the HSE regarding the accident in November. The HSE
factory inspector visited the operational plant recently and found that all was in order.


Environmental Issues

I am pleased to report that there were no incidents or external reports arising from
environmental incidents at the plant during April 2002.


Environmental Monitoring

Monitoring for bio-aerosols took place during the month of April in accordance with the
conditions as set out under the recently issued waste management license.

Date of the monitoring was that of 22nd April and therefore results from this suite of
analysis are expected back in May.


Visitors to the Site

A total of 30 visitors attended the site following invitations from Premier Waste
Management during April 2002.

A total of 19 visitors attended the site following invitations from CPS Civic and Hadee
Engineering during April 2002.


Preparations for the Senior Governmental Official

Preparations for the visit of the Senior Government official were ongoing during the
month of April and the site is now looking of a significantly higher standard than had
been expected.

Work and further operations to maintain this high quality standard at the site will of
course continue to be of paramount importance.

Photographs showing the progress of the site and equipment will be sent to yourselves
in CD format. The reason for this is that some of the photograph files of such a high
quality that the practicality of sending the file over e-mail would be impossible. (Some of
the photograph files are approximately 40MB)

Other Comments

The CE Declaration of conformity was issued by CPS on 12 th April, of which a copy is
attached to this document.

Any other information required in the mean time please call or e-mail me.
