State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q,

The Registrant requires additional time to finalize the review and processing of

delays in gathering information for inclusion in the Report associated
therewith. The Registrant further represents that the Form 10-QSB will be filed

due.

      Charles E. Coppa, CFO         781                  224-2411
      -----------------------  ---------------  ----------------------------
            (Name)              (Area  Code)         (Telephone  Number)

(2)   Have all other periodic reports required under Section 13 or 15(d) of the
      Securities Exchange Act of 1934 or Section 30 of the Investment Company
      Act of 1940 during the preceeding 12 months or for such shorter period
      that the registrant was required to file such report(s) been filed? If
      answer is no, identify report. |X| Yes |_| No

(3)   Is it anticipated that any significant change in results of operations
      from the corresponding period for the last fiscal year will be reflected
      by the earnings statements to be included in the subject report or portion
      thereof? |X| Yes |_| No




      If so attach an explanation of the anticipated change, both narratively
      and quantitatively, and, if appropriate, state the reasons why a
      reasonable estimate of the results cannot be made.

In September 2005, due to the magnitude of continued operating losses, our Board
of Directors approved separate plans to divest the operations of our Georgia and
Tennessee subsidiaries and dispose of their respective assets. Accordingly, we
have classified their respective results of operations as discontinued
operations for all periods presented.

Net sales for the three months ended March 31, 2006 decreased approximately
$782,000 to $3,911,000 compared to last year's net sales of $4,693,000. The
decrease was attributable to the completion of an Iowa scrap tire cleanup
project during fiscal 2005.

We estimate the aggregate net loss from continuing operations for the quarter
ended March 31, 2006 increased approximately $257,000 to $1,260,000 as compared
to a net loss of $1,003,000 for the quarter ended March 31, 2005. The increase
is primarily attributable to an increase of approximately $138,000 in interest
and financing costs and an increase of approximately $144,000 in administrative
costs primarily due to increased professional expenses.

The loss from discontinued operations decreased approximately $863,000 to
$21,000 for the three months ended March 31, 2006 as compared to $884,000 for
the quarter ended March 31, 2005. The decrease was attributable to the fact our
Tennessee operation was sold in September 2005 and our Georgia operations were
curtailed as of December 31, 2005.

As a result of the foregoing, we estimate our net loss deceased approximately
$608,000 to $1,280,000 for the quarter ended March 31, 2006 as compared to
$1,888,000 during the quarter ended March 31, 2005.
