Preventing Air Pollution

ISSU uses ESP and Caustic Scrubber for control emission to Prevent Air Pollution

The exhaust gas flowing from a Sulfonation reactor contains impurities such as sulfur trioxide (SO₃) gas, sulfur dioxide (SO₂) gas, and liquid acid mist. These impurities are corrosive or hazardous acidic gases. It must therefore be cleaned before being delivered to the atmosphere. To control and prevent air pollution, ISSU uses ESP (Electrostatic Precipitator) and Caustic Scrubber technologies..

In an ESP, the mist acid liquid containing the flowing gas is efficiently separated. The particle mists suspended in the gas when passing through a high-voltage electrostatic field are ionized and attracted. The mists separated, precipitated, and coagulated, forming a liquid that flows downward by gravity, collected, and sent to hazardous waste treatment.

A caustic scrubber system neutralizes and removes acidic gases from exhaust streams, ESP, through chemical reactions. These systems use a caustic solution to absorb and react with harmful acidic gases such as sulfur trioxide (SO₃) and sulfur dioxide (SO₂). Our caustic scrubber systems achieve high removal efficiencies.

ISSU routinely assesses emission gas quality to ensure the exhaust gas is compliant with the environmental regulation. The emission assessment is conducted by an external laboratory accredited by a national certification body. ISSU remain in compliance with air quality standards and promote safe conditions for our employees and the surrounding community.

Solar Photovoltaic (PV) System

ISSU reduces Carbon Emission through Rooftop Solar Photovoltaic System Installation

In line with our commitment to alternative renewable energy sources and efforts in carbon emission reduction, ISSU has successfully installed a 287 kWh rooftop solar photovoltaic (PV) system at its Plant.

This project is not merely seen as a cost reduction strategy but also sets as look for more renewable energy alternatives for a better future. ISSU has been and will always be committed to implementing a sustainable business practice.

The solar panel produce and supplies electricity 1500 kWh per day, which will reduce about 220 tons of Carbon dioxide (CO₂) emission annually or equivalent to 30000 trees planted.

Compressed Natural Gas (CNG)

ISSU TRANSITIONS TO CLEANER ENERGY

Indonesia, with its diverse range of natural resources and growing energy needs, is exploring various options to meet its energy demands sustainably. Compressed Natural Gas (CNG) is emerging as a promising solution. CNG is one of the innovative solutions to meet the increasing energy needs.

ISSU operates Boiler diesel fuel with the capacity to produce 2,500 kg of steam per hour, it is used in production processes. Started in June 2024, ISSU has diversified the Boiler fuel with CNG. CNG is a cleaner-burning alternative to diesel fuel. It consists primarily of methane, a hydrocarbon that, when burned, produces fewer pollutants compared to other fossil fuels.

CNG is Lower Emissions:

One of the primary reasons CNG is considered eco-friendly is its lower emission profile. Compared to diesel, CNG produces significantly fewer carbon dioxide (CO₂) emissions, which is beneficial for mitigating climate change. Additionally, CNG emits lower levels of nitrogen oxides (NOx) and particulate matter, which helps in reducing air pollution. CNG also reduce Greenhouse Gas Emissions: Methane, the main component of CNG, has a lower carbon content compared to diesel. This results in reduced greenhouse gas emissions per unit of energy produced.

Preserving a Sustainable Environmental Ecosystem

ISSU Environmental Conservation Strategy With Consistent Implementation of Tree Planting

Indo Sukses Sentra Usaha (ISSU) is committed to preserving a sustainable environmental ecosystem, including tree planting inside the plant location and the surrounding outside plant area.

ISSU is actively involved in planting trees in collaboration with many stakeholders , including the Environmental Local Agency , local environmental NGOs, the farmer communities, and others.

In 2020, ISSU carried out the tree planting conservation in Andonosari village, Pasuruan, East Java. In 2022, furthermore, ISSU was also involved in planting trees in collaboration with Parerejo village and Prigen District. In 2023, ISSU involved the community in tree planting in Jatiarjo village.

Environmental conservation through tree planting can create significant positive impacts on the surrounding environment. Planting trees is not only a land restoration measure but also a long-term investment in environmental sustainability. Trees play a role as soil improvement agents, helping to reduce soil erosion, enhance soil quality, and contribute to biodiversity conservation and carbon absorption.

Inside the area of the plant location, ISSU is also planting and growing many fruit trees, including mango trees, banana trees, durian trees, guava trees, aloe vera, etc. We believe those trees will effectively reduce carbon emissions and help to provide clean air in the surrounding plant area.
