                 FORM 10-K FOR THE YEAR ENDED DECEMBER 31, 2008

General

     filings.

2.   We  continue  to await the  filing of your  amended  Form 10-K for the year
     ended  December 31, 2007 to  reclassify  various  items from  non-operating
     expenses into  operating  expenses.  When you file your restated Form 10-K,

Consolidated Financial Statements

Note 3, Significant Accounting Policies

Net Loss Per Common Share

3.   Potential future dilutive securities include 996,279 of outstanding options
     and  warrants,  407,115,928  of  shares  issuable  for  the  conversion  of
     convertible  debentures,  and  62,800,925  of  shares  issuable  after  the
     conversion  of the Series B Preferred  stock under the employee  pool.  The
     amount of potential future dilutive securities appears to exceed the number
     of available authorized shares.  Please tell us what consideration you gave
     to paragraph 19 of EITF 00-19 in accounting for these contracts.

     Response:

     Although the Company  would be required to obtain  shareholder  approval to
     increase the authorized  shares to cover all potentially  issuable  shares,
     such  approval  has been under the control of the  Company as the  Chairman
     beneficially owns the majority of the Company's  outstanding voting shares.
     Therefore,  and with respect to EITF 00-19, there is effectively no control
     or contingencies to control outside of management.

     This week, the Company plans to file an  information  statement on Form 14C
     with  respect to amending its  certificate  of  incorporation  to authorize
     additional  shares of common stock  sufficient  to allow  conversion of the
     Company's various convertible securities.

Note 9, Goodwill and Intangible Assets

4.   Please disclose your  consideration  of the recurring losses in the Biofuel
     Production & Sales segment in testing this  reporting  unit's  goodwill for
     impairment  in your annual  assessment of goodwill as of December 31, 2008.
     We also  remind  you that  paragraph  28 of SFAS 142  requires  you to test
     goodwill of a reporting  unit for  impairment  between  annual  tests if an
     event occurs or circumstance  change that would more likely than not reduce
     the fair value of a reporting unit below its carrying amount.

     Response:

     The goodwill of the Company's Biofuel Production & Sales segment was tested
     for impairment as of December 31, 2008. At that time, the Company was party
     to a Membership Interest Purchase and Equity Capital Contribution Agreement
     (the "ECCA Agreement") with CleanBioenergy Partners, LLC, a special purpose
     company owned by a subsidiary of GE Energy  Financial  Services,  a unit of
     General  Electric  Company,  and by a subsidiary of YA Global  Investments,
     L.P., a private  investment  firm managed by Yorkville  Advisors,  LLC. The
     ECCA Agreement provided for the investment by CleanBioenergy of $38 million
     in equity  financing to support the construction of facilities based on the
     Company's  corn oil extraction  technologies  and the expansion of what was
     then  the  Company's  Adrian,  Michigan-based  biodiesel  refinery.  As  of
     December 31, 2008,  the  completion of this financing was expected in early
     2009.

     The ECCA  Agreement  was amended  effective  January 31, 2009 to extend the
     time for  closing  under  the ECCA  Agreement  to March 2,  2009.  The ECCA
     Agreement  was the subject of a Current  Report on 8-K filed by the Company
     on December  16, 2008,  and the  amendment  to the ECCA  Agreement  was the
     subject  of a Current  Report on 8-K filed by the  Company on  February  3,
     2009. The ECCA Agreement was terminated in March 2009,  which event was the
     subject of a Current Report on 8-K filed by the Company on March 6, 2009.

     While the ECCA  Agreement was  terminated in March 2009, the ECCA Agreement
     was in effect as of the December 31, 2008 balance sheet date. The Company's
     Biofuel Production & Sales would not have been impaired as of said date had
     the ECCA Agreement closed as anticipated.

     Please note,  however,  that the Company wrote-off all goodwill  associated
     with the  Company's  Biofuel  Production & Sales  segment  during the three
     months ended March 31, 2009. As disclosed in Note 17, Subsequent Events, in
     the Company's 10-Q for the three months ended March 31, 2009:

          "Effective May 15, 2008, the Company and Biofuel Industries Group, LLC
          (d/b/a  NextDiesel(TM))  ("BIG")  entered  into an Exchange  Agreement
          pursuant to which the Company  exchanged  20,000,000 common shares and
          20,000  preferred  shares  in  return  for 100% of the  equity  of BIG
          subject to the  redemption by BIG of BIG's "Class A Membership  Units"
          for a total of $9 million  preferred equity interest with a 12% coupon
          commencing  January  30, 2009 at a rate equal to 30% of BIG's net cash
          flows (after all  operating  costs and regular debt payments have been
          paid)  (the"Class A  Redemption").  The Company's  ownership of BIG is
          subject to  rescission  in the event  that:  (a) the BIG Loans are not
          timely serviced and kept in good standing,  (b) the Guaranty Payments,
          to the  extent  due,  are not  timely  made,  and  (c) if the  Class A
          Redemption  payments  are not made to the extent that they are due. In
          addition,  BIG's agreements with its senior  creditor,  Citizens Bank,
          require  Citizens  Bank to provide  its  written  consent to change of
          control  transactions.  Citizens Bank had previously  consented to the
          change of control of BIG on the condition  that the Company  closed on
          its prior financing agreements with CleanBioenergy  Partners, LLC (see
          Note 12,  Commitments  and  Contingencies).  This financing  failed to
          close as expected in March 2009 despite the Company's  compliance with
          the relevant agreements,  and Citizens Bank consequently  withdrew its
          consent  to the change of control  of BIG.  The  Company  subsequently
          entered into  negotiations  in April 2009 to restructure  the terms of
          the BIG  acquisition,  however,  a notice of default  of the  Exchange
          Agreement was declared on May 14, 2009 in order to maintain compliance
          with BIG's loan  agreements  with Citizens Bank.  While the Company is
          actively  pursuing debt and equity  capital to subsidize the expansion
          of the Adrian refinery, the Company does not intend to restructure the
          original  acquisition  transaction at this time. Instead,  the Company
          intends  to  facilitate   rescission   of  the  original   acquisition
          transaction  and the  divestiture of BIG during the quarter ended June
          30, 2009 due to changed market circumstances. The Company may consider
          acquiring  an equity  stake in BIG in the  future  if it  successfully
          raises  sufficient   capital  to  expand  the  Adrian  refinery.   The
          divestiture  of BIG has not been  completed  as of the filing  date of
          this report,  however,  the financial  results of this subsidiary have
          been presented as discontinued operations as and for the quarter ended
          March 31,  2009 (see Note 6,  Discontinued  Operations).  The  Company
          wrote-off  $7,281,993 in goodwill previously booked in connection with
          the  acquisition  of  BIG.  The  Company's  divestiture  of BIG can be
          expected to result in the disposal of $13,054,855  and  $23,554,858 in
          assets and liabilities, respectively."

Note 16, Debt and Purchase Obligations:  Citizens Bank

5.   We note your response to comment 8 from our letter dated February 26, 2009.
     As previously requested,  please revise your filing to disclose your actual
     debt covenant  ratios in addition to your  required  debt covenant  ratios,
     with corresponding  reconciliations to US GAAP amounts, if necessary.  This
     will  help  investors  understand  the  extent  to  which  you  are  out of
     compliance  with your debt  covenants  or how close you are to  potentially
     violating  your  debt  covenants.  Given  that you are in  default,  please
     disclose how these debt amounts are classified on your balance sheet. Refer
     to EITF 86-30.

     Response:

          The Company  plans to file an amended  2008 Form 10-K  promptly  after
          confirming  that the Staff has no further  comments.  The amended 2008
          Form 10-K will contain the following disclosure:

          Biofuel Industries Group, LLC ("BIG") and Citizens Bank entered into a
          Loan  Agreement on January 11, 2007,  which provides for the following
          financial covenants:

          Debt Service  Coverage - BIG shall  maintain a debt  service  coverage
          ratio of not less  than  1.25 to 1.00,  which  ratio  shall be  tested
          quarterly.

          Leverage - BIG shall  maintain a ratio of  liabilities to tangible net
          worth of not more than 3.00 to 1.00.

          Liquidity  - the  personal  guarantors  of the  Loan  Agreement  shall
          maintain  at  all  times  cash  and  marketable   securities  totaling
          $3,750,000.

          As of  December  31,  2008,  BIG was not in  compliance  with the Debt
          Service  Coverage and Leverage  covenants.  A schedule with the actual
          and required ratios,  with a corresponding  reconciliation  to US GAAP
          amounts, is provided here:

          Non-GAAP Financial Measures

          It should be noted, in connection with review of the preceding  table,
          that EBITDA is not a financial  measure employed in the application of
          generally accepted  accounting  principles.  Nevertheless,  we believe
          that earnings before interest expense, income tax provision (benefit),
          depreciation  and  amortization,  or EBITDA is useful to investors and
          management in  evaluating  our  operating  performance  in relation to
          other companies in our industry.  the calculation of EBITDA  generally
          eliminates the effects of financings and income taxes, which items may
          vary  for  different   companies  for  reasons  unrelated  to  overall
          operating  performance.  In addition, we have calculated the effect of
          eliminating non-recurring items, so as to enable meaningful comparison
          between  years.  EBITDA  is  a  non-GAAP  financial  measure  and  has
          limitations  as an  analytical  tool,  and should not be considered in
          isolation  or as a substitute  for net income or any other  measure of
          performance under GAAP, or to cash flows from operating,  investing or
          financing  activities  as a measure of liquidity.  We  compensate  for
          these  limitations  by relying on our GAAP results,  as well as on our
          EBITDA.

     In  accordance  with EITF 86-30,  the portions of the debt that do not meet
     the covenant  requirements  have been  classified as current on the balance
     sheet.

Note 16, Debt and Purchase Obligations:  Sustainable Selling Shareholders

6.   You disclose  that you  recognized  a gain of $4.5 million  during the year
     ended  December  31,  2008 as a result of the  forgiveness  of debt by Paul
     Miller,  a former  shareholder of Sustainable and the current  President of
     Sustainable.  Please tell us how you  considered  the guidance  provided in
     footnote 1 of paragraph 20 of APB 26 in determining the  appropriateness of
     your accounting treatment.

     Response:

     The Company's  debt to Paul Miller was incurred in payment for his interest
     in  Sustainable  Systems.  That  purchase  was made at arm's length from 23
     selling shareholders.  Prior to the purchase Mr. Miller had no relationship
     with the Company. The debt was forgiven by Mr. Miller in consideration of a
     release by the Company of its claims against Mr. Miller, arising out of the
     failure  by Mr.  Miller  to  disclose  material  facts  at the  time of the
     acquisition. At the time of the forgiveness, Mr. Miller was a member of the
     management  of  Sustainable  Systems,  but had no role in management of the
     parent  Company.  The  forgiveness  was a  settlement  negotiated  at arm's
     length. In these circumstances,  the guidance in footnote 1 of paragraph 20
     of APB 26 does  not  appear  applicable,  as the  transaction  has far more
     characteristics  of an arm's  length  transaction  than of a related  party
     transaction.  Accordingly,  the  transaction was recorded as forgiveness of
     non-related party debt.

Note 17, Embedded Derivatives

7.   It appears that the $1,386,851 of convertible debentures issued to MIF also
     contain  variable  conversion  features.  Please clarify your disclosure to
     address  what  consideration  you  gave to the  conversion  terms  of these
     debentures pursuant to EITF 00-19.

     Response:

     FASB 150 paragraph 12a states that a financial  instrument that embodies an
     unconditional   obligation,   or  a  financial  instrument  other  than  an
     outstanding share that embodies a conditional  obligation,  that the issuer
     must or may settle by issuing a variable  number of its equity shares shall
     be  classified  as a  liability.  The  Company  will amend its  disclosures
     relative to the treatment of the  conversion  terms of the debentures to be
     consistent  with  FASB 150  paragraph  12a.  The  Company  plans to file an
     amended 2008 Form 10-K  promptly,  after  confirming  that the Staff has no
     further comments.

Item 9A, Controls and Procedures

8.   Your  current  disclosures  do  not  provide  management's   evaluation  of
     disclosure  controls and  procedures  nor internal  controls over financial
     reporting as of December 31, 2008.  Please amend your filing to include all
     of the disclosures required by Items 307 and 308T of Regulation S-K.

     Response:

     The  Company  plans  to file an  amended  2008  Form  10-K  promptly  after
     confirming  that the Staff has no further  comments.  The amended 2008 Form
     10-K will contain the following disclosure under Item 9A:

     (a)  Evaluation of disclosure controls and procedures

          The term  "disclosure  controls and  procedures"  (defined in SEC Rule
          13a-15(e))  refers to the controls and other  procedures  of a company
          that are designed to ensure that information  required to be disclosed
          by a  company  in the  reports  that it  files  under  the  Securities
          Exchange  Act of 1934 (the  "Exchange  Act") is  recorded,  processed,
          summarized  and reported,  within time periods  specified in the rules
          and  forms of the  Securities  and  Exchange  Commission.  "Disclosure
          controls and procedures"  include,  without  limitation,  controls and
          procedures  designed  to  ensure  that  information   required  to  be
          disclosed by a company in the reports  that it files or submits  under
          the Exchange Act is  accumulated  and  communicated  to the  company's
          management,  including its principal executive and principal financial
          officers,  or persons performing similar functions,  as appropriate to
          allow timely decisions regarding required disclosure.

          The  Company's  management,   with  the  participation  of  the  Chief
          Executive Officer and the Chief Financial  Officer,  has evaluated the
          effectiveness of the Company's  disclosure  controls and procedures as
          of  the  end  of  the  period  covered  by  this  annual  report  (the
          "Evaluation  Date").  Management  determined  that, at the  Evaluation
          Date,  the Company had a material  weakness  because it did not have a
          sufficient  number of personnel with an appropriate level of knowledge
          of and experience in generally accepted  accounting  principles in the
          United  States of  America  (U.S.  GAAP) that are  appropriate  to the
          Company's financial reporting requirements.  Based on that evaluation,
          the Company's Chief Executive Officer and Chief Financial Officer have
          concluded  that,  as  of  the  Evaluation   Date,  such  controls  and
          procedures were not effective.

     (b)  Changes in internal controls

          The term "internal control over financial  reporting"  (defined in SEC
          Rule 13a-15(f)) refers to the process of a company that is designed to
          provide  reasonable  assurance  regarding the reliability of financial
          reporting and the  preparation  of financial  statements  for external
          purposes in accordance with generally accepted accounting  principles.
          The  Company's  management,   with  the  participation  of  the  Chief
          Executive  Officer and Chief  Financial  Officer,  has  evaluated  any
          changes in the Company's  internal  control over  financial  reporting
          that  occurred  during the fourth  quarter of the year covered by this
          annual report, and they have concluded that there was no change to the
          Company's   internal   control  over  financial   reporting  that  has
          materially affected, or is reasonably likely to materially affect, the
          Company's internal control over financial reporting.

     (c)  Management's Report on Internal Control over Financial Reporting

               Management of the Company is  responsible  for  establishing  and
          maintaining  adequate  internal  control over  financial  reporting as
          defined in Rule 13a-15(f)  under the Securities  Exchange Act of 1934.
          We have assessed the  effectiveness  of those internal  controls as of
          December 31, 2008, using the Committee of Sponsoring  Organizations of
          the  Treadway   Commission  ("COSO")  Internal  Control  -  Integrated
          Framework as a basis for our assessment.

               Because of inherent limitations,  internal control over financial
          reporting may not prevent or detect misstatements.  Projections of any
          evaluation of  effectiveness to future periods are subject to the risk
          that controls may become inadequate  because of changes in conditions,
          or that the degree of compliance  with the policies and procedures may
          deteriorate.   All  internal  control  systems,  no  matter  how  well
          designed,  have inherent  limitations.  Therefore,  even those systems
          determined to be effective can provide only reasonable  assurance with
          respect to financial statement preparation and presentation.

               A material  weakness in  internal  controls  is a  deficiency  in
          internal  control,  or  combination  of  control  deficiencies,   that
          adversely  affects  the  Company's  ability  to  initiate,  authorize,
          record,  process,  or  report  external  financial  data  reliably  in
          accordance with accounting principles generally accepted in the United
          States of  America  such that  there is more than a remote  likelihood
          that a  material  misstatement  of the  Company's  annual  or  interim
          financial  statements  that is more than  inconsequential  will not be
          prevented or detected.  In the course of making our  assessment of the
          effectiveness  of  internal  controls  over  financial  reporting,  we
          identified  one material  weakness  related to the  Company's  control
          environment,  in that the Company did not have a sufficient  number of
          personnel  with an  appropriate  level  of  U.S.  GAAP  knowledge  and
          experience  appropriate  to  its  financial  reporting   requirements.
          Accordingly,  management's  assessment is that the Company's  internal
          controls over  financial  reporting  were not effective as of December
          31, 2008.

          This  annual  report  does not  include an  attestation  report of the
          Company's registered public accounting firm regarding internal control
          over  financial  reporting.  Management's  report  was not  subject to
          attestation  by  the  Company's   registered  public  accounting  firm
          pursuant to temporary rules of the Securities and Exchange  Commission
          that permit the Company to provide  only  management's  report in this
          annual report.
