Prof. Sri Suhartini, STP., M.Env.Mgt., Ph.D., PGCert., IPM developed ADIB Technology Model for Sustainable Agroindustry. She was inaugurated on Sunday (15/10/2023), at Brawijaya University (UB) as Professor in the Field of Agro-Industrial Environmental Engineering at the Faculty of Agricultural Technology (FTP).

Agro-industry has a very important role in Indonesian economy. The large number of agro-industries is proportional to the increase in waste produced. The problem that often occurs is that many agro-industries dispose of their waste directly into the environment without processing. In fact, this behavior has a negative impact on the environment, biodiversity and human health.

Therefore, in the context of sustainable agro-industry development in Indonesia, it is necessary to utilize waste based on the zero-waste concept and integrated biorefinery. The zero-waste concept means that waste must be utilized in its entirety so that the potential of becoming waste again does not occur.

One technology for utilizing environmentally friendly agro-industrial waste is anaerobic digestion technology which produces biogas and biofertilizer. In Indonesia, the application of this technology is still on a small scale with an underground system, without mixing, and has not been integrated so it is not efficient.

Prof. Sri Suhartini has developed an anaerobic digestion reactor with automatic stirring to increase process efficiency. She also developed ADIB (anaerobic digestion-integrated biorefinery) technology model, to maximize waste conversion and achieve zero-waste.

This model was developed from the multi-products biorefinery concept which prioritizes overall waste utilization through the integration of several conversion technologies.

The advantages of ADIB technology integration model are that all waste is utilized, many products are produced, the process is waste-free, and increased biogas production. This model has the potential to be applied on an industrial scale to increase economic benefits from waste. The weakness of this model is that its performance and feasibility have not been tested economically, technically and environmentally, so it is necessary to carry out performance tests and feasibility analysis, as well as develop reactor automation and integration with biogas purification/conversion systems.
