Composting is a key practice for turning unavoidable food scraps into valuable soil amendments, closing the sustainability loop in kitchens. Proper composting methods reduce landfill waste and greenhouse gases while enriching gardens.
Composting Basics
Balance “greens” (nitrogen-rich scraps like vegetable peels, fruit waste) with “browns” (carbon-rich materials like dry leaves, shredded paper) at about a 2-3:1 ratio. This mix promotes decomposition without odors.
Avoid meats, dairy, and greasy foods which disrupt compost health.
Composting Methods
Hot Composting: Builds heat (110°F to 160°F) to break down materials quickly (weeks to months). Requires regular aeration and moisture control.
Cold Composting: Easier and slower (6 months to 2 years), less maintenance, suitable for beginners.
Bokashi Composting: Fermentation process using microbes in a sealed bin; works indoors with minimal odor.
Compost Tumblers: Contained bins that make turning and aeration simple, speeding composting.
Trench Composting: Directly burying scraps in soil to decompose naturally over time.
Circular Systems
Integrate composting with kitchen operations by:
Segregating scraps at prep stations into compost bins.
Freezing or storing scraps for batch composting.
Using finished compost for hotel gardens or local farms.
Partnering with composting services if on-site composting isn’t feasible.
Benefits
Composting cuts waste hauling costs, reduces carbon footprint, and nourishes soil. Kitchen teams in Dubai report improved engagement in sustainability by closing the waste loop.
