The district is the site of some of Thailand's largest
e-waste recycling businesses. Tambon Khok Sa-at in particular has 154 households that purchase old electronic devices, sort them, and extract scrap electronics for materials that can be reused or recycled and sell them to a third party. They process about 1,000 tonnes of scrap per month. An environmental issue is the remaining 24 tonnes of worthless material that must be disposed of. Absent any local disposal facilities, the scrap is trucked to incinerators in
Sa Kaeo and
Saraburi. Health officials maintain that levels of contaminants are low and do not pose a threat to people's health or the ecosystem. ==Administration==
