Distribution of Hazardous and Non-Hazardous Waste by Province in 2021

Waste is a significant problem in Indonesia because it contains materials that can cause pollution and harm health. Waste is categorized into B3 waste (hazardous and toxic materials) and non-B3 waste.

The Ministry of Environment and Forestry (KLHK) recorded that the production of B3 and non-B3 waste in West Nusa Tenggara (NTB) province reached 19.9 million tons in 2021. This makes the province the largest waste producer in Indonesia.

West Java is second with B3 and non-B3 waste production of 8.82 million tons last year. Banten follows in third place with 6.46 million tons.

B3 and non-B3 waste production in North Sumatra was recorded at 6.19 million tons. East Java and Riau follow with production of 6.1 million tons and 3.76 million tons respectively.

Of the 34 provinces in Indonesia, only NTB produced more than 10 million tons of B3 and non-B3 waste. Eighteen provinces produced 2-10 million tons, while the remaining 15 provinces produced less than 2 million tons.

Maluku had the lowest production, at only 2,500 tons. Above it are West Sulawesi and West Papua with production of 3,300 tons and 3,900 tons respectively.

Quoting *dlh.bulelengkab.go.id*, B3 waste is waste whose nature and concentration contain toxic and hazardous substances that can directly or indirectly damage the environment, disrupt health, and threaten the survival of humans and other organisms.

Waste is classified as hazardous and toxic if it has characteristics such as being explosive, oxidizing, flammable, toxic, corrosive, and causing health problems. Non-B3 waste does not contain the characteristics of B3 waste.
