Household Waste Processing Research Program

Collaboration of:
Sustainable Waste Indonesia
Bakti Bumi

Bakti Bumi has long been a steadfast and dedicated player in the waste industry. While its inaugural waste processing facility, TPS3R in Sidoarjo, took root in 2015, the company’s involvement in plastic recycling predates this milestone. Founded by the esteemed Bapak Marsono, a seasoned figure within a national company renowned for its machinery competence, Bakti Bumi has since expanded to multiple locations, earning the trust of local government authorities for its operational systems. Initially grappling with the challenge of balancing waste processing efficiency with financial viability, particularly in managing the residual waste destined for landfills, the company navigated its early stages with resilience.

In 2018, Sustainable Waste Indonesia and Bakti Bumi joined forces under an MoU aimed at researching and developing household waste processing systems. Our shared objective was to devise solutions that are not only locally accessible and socially acceptable but also economically feasible. Central to this endeavor was the imperative to tackle low-value materials and residual waste, with a focus on maximizing waste conversion into valuable products, spanning materials recycling and energy recovery.

Despite the geographical distance between Sustainable Waste Indonesia in Jakarta and Bakti Bumi in Sidoarjo, our collaboration has flourished, driven by a shared commitment to overcoming challenges and seizing opportunities. Since 2020, our partnership has yielded significant milestones, including the production of RDF fluff and briquettes at TPS3R Puri, Sidoarjo. These products found eager buyers among SMEs with industrial boilers, such as noodle and chip factories, as well as plastic manufacturer. Moreover, Bakti Bumi’s efforts extended to producing pulverized RDF for a trial program at Pembangkit Jawa Bali (PJB) in 2022, alongside its accreditation as a verified RDF supplier to Solusi Bangun Indonesia (SBI) – Tuban Plant. The collaborations with Sustainable Waste Indonesia, alongside other projects, have empowered Bakti Bumi to consistently enhance its systems, machinery, innovations, and business models.

In the wake of the escalating waste landfill crisis in numerous cities in 2023, Bakti Bumi’s momentum surged, underscored by the urgent need for household waste processing solutions to alleviate landfill burdens. Initiating operations in Sleman City, Yogyakarta Province, the company swiftly implemented its waste processing systems, converting waste into RDF for Solusi Bangun Indonesia (SBI) – Cilacap Plant. This marked the beginning of a widespread expansion, with Bakti Bumi’s systems being deployed across multiple cities, each capable of an incoming waste capacity ranging from 20 to 100 tons per day. Presently, 12 plants are operational, with an additional 13 line up for installation in Yogyakarta Province, Banyuwangi, Bali, and West Java. Concurrently, Bakti Bumi continues its supply of RDF to SCG (Thailand cement) – Sukabumi Plant and industrial boilers, strengthening its role in advancing circular economy principles.

Our collaborative efforts remain steadfast in addressing waste challenges, prioritizing swift and high-capacity waste conversion into valuable products to promote circular economy principles. To achieve this goal, continuous innovation entails collaborating closely with waste stakeholders to devise efficient on-site technologies, all the while fostering partnerships with product off-takers. In the case of RDF, this approach aims to establish a comprehensive supply chain ecosystem encompassing cement industries, industrial boilers, and preferably, power plants.
