In addition to hazardous materials, the policy on waste disposal also covers the reusing and recycling of waste (https://the.undip.ac.id/download/18sdg12/waste%20disposal.pdf). The garbage that can be reused will be separated and not be disposed to landfill, for instance papers. The organic waste are recycled to produce more valuable stuffs such as fertilizer. The inorganic waste such as plastics are crushed and then sold for recycling to third parties. Only the garbage that cannot be reused and recycled will be sent to landfill. The policy is consistently implemented to date.
