Amendment Description	This Amendment No. 1 on Form 10-K/A (this "Amendment") amends the Annual Report on Form 10-K of SusGlobal Energy Corp. (the "Company") for the period ended December 31, 2023, originally filed with the Securities and Exchange Commission (the "SEC") on May 15, 2024 (the "Original Form 10-K"). This Amendment is being filed for the sole purpose of filing complete dated certifications in the form of Exhibits 31.1, 31.2, 32.1 and 32.2 (the "Certifications"), respectively. The Certifications were inadvertently not dated on the date of filing the Original Form 10-K, and as such, are now dated concurrently with this Amendment. This Amendment contains only the cover page, this explanatory note, the signature page and the Certifications. No other changes have been made to the Original Form 10-K. This Amendment speaks as of the original filing date of the Original Form 10-K, does not reflect events that may have occurred subsequent to the original filing date and does not modify or update in any way disclosures made in the Original Form 10-K. Accordingly, this Amendment should be read in conjunction with the Original Form 10-K and the Company's other filings made with the SEC subsequent to the filing of the Original Form 10- K.
