SECTION 5 – COMPOSTING AREA <br />EN1213161143SAC INSERT LEGAL ENTITY (IF APPLICABLE) 5-3 <br />5.4 Amendments <br />Amendments are normally added to organic feedstocks as part of the composting process. This is done to <br />adjust the moisture content and carbon-to-nitrogen ratio to the desired range. In addition, amendments <br />provide structure and free air space to improve the movement of air through the composting pile. <br />While the necessary adjustments can often be achieved through the use of one amendment type, it is <br />not uncommon to use two or more amendments to achieve the desired results. Amendments may also <br />be added to curing piles or to finished compost product to enhance their agronomical characteristics. <br />The following are common amendment sources that may be used at the compost facility: <br />• Wood chips produced from onsite grinding of wood waste, dimensional lumber and logs, stumps, or <br />brush, or purchased from material brokers <br />• Oversized material screened from finished compost produced at the site (screening overs) <br />• Leaves and brush from leaf and yard waste diversion programs <br />• Cardboard and paper <br />• Sawdust <br />• Straw <br />Actual quantities and types of amendments used at the site will vary from week to week depending on <br />feedstock characteristics and amendment availability.
