Global egg production for the year 2018 was 78 million metric tons, contributing approximately 8.58 million metric ton of eggshells, which are being discarded mostly as waste. On reaching landfills, the egg white attached to eggshells start to decompose and rot, promoting the growth of microbes that produce amides, ammonia and sulfides when breaking down organic matter, creating a smelly by-product which attracts other pests. On an average, hens in the UK lay 11 billion eggs annually. This generates 80,000 tonnes of eggshell waste each year.
