DPCC categorizes industries into four distinct groups based on their potential to induce pollution, which has been stated below:

Industries falling under the red category: Red category industries, encompassing activities like thermal power generation, chlor-alkali production, integrated iron and steel plants, pesticide manufacturing, fertilizer production, distilleries, and pulp and paper manufacturing, are those that generate more than 1000 kg of hazardous waste per day or consume over 12.5 MT of fuel daily.
Industries falling under the orange category: Industries categorized as orange, which encompass operations like textile dyeing and printing, bulk drug manufacturing, cement plants, foundries, electroplating, and sugar mills, hold a notable potential for pollution. This potential is characterized by generating more than 100 kg of hazardous waste daily or having a fuel consumption exceeding 2.5 MT per day. Moderate pollution control measures are mandated for these industries.
Industries falling within the green category: Industries classified under the green category, which encompasses activities like packaging, labeling, textile processing, printing presses, and paper and pulp manufacturing, generate hazardous waste below 100 kg daily and have a fuel consumption of less than 2.5 MT per day. These industries necessitate fundamental pollution control measures.
Industries Classified as White Category: White-category industries encompass those with the least potential for causing pollution and, hence, do not demand pollution control measures. Such industries involve sectors like software development, BPOs, and call centers.
