PLTSa Merah Putih Ubah Sampah Bantar Gebang Jadi Energi Listrik

Summary

The video discusses the waste management efforts at the Bantargebang landfill in Jakarta, focusing on the PLTSA (Waste-to-Energy Power Plant) that processes waste through thermal technology. The plant burns waste to generate electricity, with a capacity of processing 100 tons per day. Key aspects include waste sorting, recycling, and the generation of electricity (750 kWh daily). The video highlights Indonesia’s national efforts to address waste in 12 cities, including Surabaya, with ongoing projects. Despite challenges like mixed waste, the goal remains to reduce waste while using waste as a resource for energy.

Takeaways

• 😀 The Bantar Gebang waste processing facility in Jakarta handles up to 100 tons of waste per day using thermal waste-to-energy technology.
• 😀 The facility generates approximately 750 kWh of electricity per day from the waste it processes.
• 😀 Waste is first sorted at the facility, with non-burnable materials like metals, hazardous waste, and recyclable items being separated.
• 😀 Organic waste is also sorted for composting and used as fertilizer, reducing the environmental impact of waste disposal.
• 😀 The remaining waste is incinerated to generate heat, which powers turbines that produce electricity.
• 😀 The facility also manages ash from the incineration process, most of which is landfilled, while some is reused for making building blocks.
• 😀 The energy produced is used internally at the facility, including powering streetlights and other operations, rather than being sold to the national grid.
• 😀 Indonesia’s government, through President Regulation No. 35 of 2018, aims to accelerate waste management projects in 12 cities, with waste-to-energy plants being a key part of this effort.
• 😀 Surabaya is one of the leading cities in Indonesia with two waste-to-energy plants generating a total of up to 10.65 MW of electricity.
• 😀 Mixed waste remains a challenge in Jakarta, as the waste is often not properly sorted before being processed, lowering the efficiency of waste-to-energy operations.
• 😀 The government is working to improve waste sorting and recycling efforts in urban areas, which will enhance the efficiency of waste-to-energy plants and reduce landfill use.

Q & A

What is the current height of the waste pile at Bantargebang?

The current waste pile at Bantargebang has reached almost 60 meters.

What collaboration led to the development of the waste processing facility in Bantargebang?

The waste processing facility in Bantargebang was developed through a collaboration between the DKI Jakarta Provincial Government and BPPT.

How does the waste-to-energy process work at the Bantargebang facility?

At the Bantargebang facility, waste is burned to produce heat, which then generates steam in a high-pressure boiler. This steam drives a turbine connected to a generator, producing electricity.

What is the processing capacity of the Bantargebang facility?

The facility has a processing capacity of 100 tons of waste per day, which generates about 750 KWh of electricity daily.

What steps are taken before burning the waste at Bantargebang?

Before burning, the waste is sorted in a pre-treatment facility to separate materials that do not burn, such as metals, B3 waste, and recyclable items. Large-sized waste is also filtered out.

How is organic waste handled at the Bantargebang facility?

Organic waste is separated and can be used as fertilizer. It is ideally kept to a minimum in the waste processed at the facility to prevent it from adding moisture to the waste, which would lower its calorific value.

What happens to the ash produced by the waste incineration process?

The ash is mostly sent to a landfill near the facility, but some of it is repurposed for making paving blocks and bricks. It is used internally until there is excess demand from the community.

What additional utilities are powered by the electricity generated at the Bantargebang facility?

The electricity generated is used internally at the Bantargebang facility, including powering street lights and other infrastructure, but it is not sold to the national grid (PLN).

How does the government aim to tackle waste management across Indonesia?

The government is accelerating waste management efforts through a presidential regulation (Presidential Regulation No. 35 of 2018), identifying 12 cities as part of a fast-track waste handling program. The aim is to generate electricity from waste to help manage the large amount of waste produced daily.

Which cities in Indonesia have waste-to-energy plants operating, and how significant are they?

As of now, two cities, Surabaya and Jakarta, have operational waste-to-energy plants. Surabaya has two units: one with a capacity of 1.65 MW and another with a capacity of 9 MW, which are already supplying electricity to PLN.
