Surprised by the way garbage is thrown away in Indonesia

Twenty-three years ago, when I first came to Indonesia, one of the things that gave me a culture shock in my daily life was the fact that it was normal for people to leave trays of wrappers and leftover Coke on the tables at fast food restaurants such as MacDonald and KFC.

When I couldn't stand the guilt that came from Japanese customs and wanted to throw them in the trash myself, I was admonished by a senior Japanese resident that I shouldn't act based on Japanese values because it would take away the work of the cleaning staff.

When I was living in Tokyo, the rules for garbage disposal were not as strict as they are now, and at most, we had to sort garbage into combustible and non-combustible, and place garbage bags neatly under a net to prevent crows from scavenging.

The garbage is now subdivided not only into combustible and non-combustible, but also into spray cans, cassette cylinders, plastic bottles, used paper, bottles and cans.

Jakarta's inorganic waste recycler sorts, cleans and cuts the waste, then sells it to a factory or exports it for reuse

PET (polyethylene terephthalate) aqua bottle ⇒ polyester thread
PP (polypropylene) aqua glass ⇒ plastic string or rice bags
HDPE (high-density polyethylene) shampoo bottle ⇒ broom or molded product

The plastic waste collector makes his living by taking the collected recyclable waste to the recycler and having them pick it up for around Rp.10,000/Kg for aqua glasses and Rp.5,000/Kg for aqua bottles.

In fact, there have always been people who are highly conscious about littering, and even my driver 20 or so years ago told me that he scolded his children strictly if they tried to litter.

In recent years, garbage cans in public places and companies have been divided into combustible and non-combustible, and even our residential areas (clusters) have been divided into orange NON ORGANIC and green ORGANIC.

The reason why people are becoming more aware of the need to separate garbage is because people are becoming more eco-conscious as the economy grows.

Indonesia's approach to resource recycling

In addition to the reuse of garbage, the city is working on resource recycling by actively recycling food waste (organic waste) from the dinner table, and by supporting the development of new products and the launch of new businesses, the city is aiming to establish a foundation for the livelihood of its residents, and is working towards an eco-system that will be passed on to the children of the next generation.

Eco-businesses supported by Bandung's horticultural garden
1. By bringing organic waste, you can earn points to exchange for seeds, fertilizer, and gardening tools, and buy vegetables grown at home at the market.
2. Support the development of new products.
3. Create new businesses and support their growth.
4. Open up to children studying biology to help them understand nature.

The wave of eco-friendliness has also spread to fertilizers for crop cultivation, and organic fertilizers to maintain and improve soil fertility are attracting attention because the excessive use of chemical fertilizers, which are essential for increasing productivity, reduces the soil organic matter content, damages the soil structure, and causes environmental pollution.

The pioneer of organic waste management in Lampung developed a composting device
1.Attach air and liquid discharge pipe to the bucket
2.Mix rice washing water with sugar, coconut solution, ketchup, honey, fruit peel and wait for about a week until it smells like tapeh to produce fungus.
3.Chop up the garbage and dump it into the machine to spread the fungus.
4. Take out the compost.regional.kompas.com/read/2019/01/2…

Home microbial organic fertilizers contain trace amounts of micronutrients (vitamins, minerals, etc.) that are necessary for proper plant development and metabolic functions, macronutrients (proteins, carbohydrates, fats, etc.) that are needed in large amounts for plant growth, and bacteria that improve soil quality. It can be used as a soil decomposer, organic fertilizer, and organic fungicide.

Once the method of making microbial organic fertilizers at home is established and popularized, the materials will be available free of charge and easy to apply to home gardens, which will help solve the problem of disposing of the large amount of organic waste generated daily from large cities such as Jakarta and Surabaya, and is expected to be environmentally friendly, free of harmful chemicals, and effective in improving soil and crop quality.
