IPB University Professor Encourages a Closed Production Process to Realize a Sustainable Agro-Industry


One of the important substances in an agro-industry is that there is still a large amount of waste generated from the processing of agricultural products. For example, 60 thousand kilograms of palm fresh fruit bunches (FFB) only produces 16,082 kilograms of crude palm oil (CPO) and 1,977 kernels. Thus, there is waste in the form of coconut shells reaching 1,959 kilograms, empty bunches reaching 14,265 kilograms, fiber waste as much as 4,613 kilograms and liquid waste reaching 21,058.

"So far, many people say that waste is a resource that we have not been able to convert into goods that are useful for humans. Meanwhile, the definition of a resource is anything that can provide benefits for life, "explained Prof. Dr. Tajuddin Bantacut, Permanent Professor of the Faculty of Agricultural Technology IPB University in the Pre-Scientific Oration Press Conference which was held online on 8/10.

In fact, he said, if the by-product of the agro-industry is processed, it will become a commodity that has a high selling value. Besides having a high selling value, the processing of these byproducts is expected to reduce the environmental burden due to industrial waste contamination.

Prof. Tajuddin explained that the by-products of agro-industry can be a source of sufficient energy generation for production and some of them can produce excess energy. He further explained that the integration of the production process flow with the use of waste for energy can be developed as a new approach in factory design. This is called closed production.

“Power generation, either direct combustion or conversion process, can be an integral part of agro-industry development from the early stages of design and planning. Apart from energy, water contained in raw materials can be used to meet process needs or to produce new products, "explained the IPB University lecturer from the Department of Agricultural Industrial Technology

Through a study he has done, the palm oil mill agro-industry with a capacity of 60 tons per hour has a potential energy from byproduct up to 65,006,768 kcal and can be converted into energy in excess of 1,022 kWh. Meanwhile, a sugar factory with a capacity of 3000 TCD has the potential energy from by-products to reach 2,237,500,774 kcal and when converted into energy, it can reach more than 60,000 kWh and an energy surplus of 55,943 kWh can be achieved.

"This energy surplus can illuminate up to three thousand households, so companies can not only produce main products such as oil from palm oil and sugar, but also produce energy that can be sold," he added.

Prof. Tajuddin also gave an example that there have been many companies in developed countries that have tried to convert their industrial waste into energy sources. Even companies in Korea import empty bunches from Indonesia to convert them into energy. (IAAS/FAP)
