"The essence of the zero waste concept is fading away. It has now become little more than a marketing buzzword. Recycling and separate garbage collection, at their peak, only contribute around *5% to tackling plastic-related issues. With time, it might improve by another 10%. Yet, if we manage to completely resolve the plastic issue, we could potentially achieve a complete 100% solution.” From SIITA's very first presentation...


‘What if plastic no longer posed a problem? The real challenge lies in its non-decomposable nature. Why not make it decompose naturally...?" During one of our weekly meetings, we decided to completely flip our perspective.

The concept is quite straightforward. Instead of dwelling on the issues arising from already discarded plastic, let's proactively prevent plastic from entering the waste stream in the first place. In other words, we aim to create plastic products that produce no waste at all after decomposition. If feasible, there is hardly a more effective solution than this. In a world devoid of waste, there would be no subsequent problems triggered by waste.

The challenge, however, seemed unparalleled in its difficulty. Plastic presented an immense issue with a decomposition period of 500 years. Everyone voiced that plastic was difficult to decompose. However, we knew that this endeavor was a must.

According to the U.S. Environmental Protection Agency, the portion of the recycled plastic among the entire plastic waste falls short of a mere 10%. Even this has remained stagnant for a decade, and in the past five years, it has even seen a decline. On the contrary, the overall volume of plastic waste has surged dramatically. In the face of the rapidly escalating issue, the world's efforts spanning decades have been overshadowed. The environmental challenges stemming from plastic waste remain unresolved.

To counter the escalating global menace, it is imperative to confront the underlying problem of plastic. This reality has become strikingly apparent before us. Hence, it didn't take us long to make our commitment to venture into this endeavor.

Journey Together


Shortly after we decided to take charge of the plastic issue, SIITA halted sales and production across the board. We donated the remaining proceeds to marine and ecosystem protection organizations, to pool all our capacities and resources toward tackling the plastic challenge. Guided by the vision of creating ‘an enduring Earth’, there was no impetus to pursue any other work. Thus, we embarked on our journey as pioneers.

Tackling the plastic issue and crafting products to prevent them from ending up as waste was, indeed, a path that was unexplored and riddled with challenges. Through research and investigations, we encountered a multitude of seemingly insurmountable obstacles—ranging from the very nature of raw materials to the constraints of decomposition technology, costs, and system scalability. The path we were heading towards was a completely unchartered territory. Nonetheless, we were not alone, with our customers accompanying us since the onset of this adventure.

Immediately after the spread of the new endeavor, our customers extended unsparing heartfelt support. Our passionate customers voluntarily began to fill their social media with SIITA’s story. Some of them picked up their pens to write articles about it. There were even individuals who engaged in research and provided funding for development. Our customers willingly took on the roles of exceptional engineers, planners, editors, and investors. SIITA and its customers were working in concert to drive this innovation and adventure. SIITA’s challenge was an extraordinary phenomenon of its kind.

Our entire business was put on a halt, yet we managed to remain deeply engrossed in research and development on the back of our customers’ enthusiastic support and assistance. Eventually, at the end of this arduous and lengthy journey, SIITA proudly succeeded in commercializing the technology of complete plastic decomposition in 2021.

Encountered Reality


What shocked us is, on the contrary to the claims that plastic would naturally disappear within a few months when buried underground without any special treatment, so-called degradable plastics were not actually undergoing any decomposition at all, until SIITA came along.

Authentic decomposition of degradable plastic requires specific conditions to be met. In particular, a very high-temperature environment needs to be maintained, which unavoidably entails significant costs.

Furthermore, the larger the scale, the higher the expenses – this is why many could easily adopt degradable plastic, yet nobody managed to truly decompose it. Few were willing to invest resources and efforts to make plastic decomposition a reality, as it sufficed to claim that "we are addressing environmental concerns through the use of degradable plastic”.

While the introduction of degradable plastic seemed to present new possibilities to the world, the reality remained that all forms of plastic were still being buried, incinerated, or flowed into the oceans. SIITA felt a justifiable anger towards the indifferent falsehoods prevalent in the world and refused to make any compromises.

Innovation in the realm of decomposition

SIITA effectively managed to conserve an enormous quantity of thermal energy that is typically necessary for plastic decomposition by harnessing the thermal energy produced through microbial activities. This enabled us to elevate plastic decomposition, which had only been achievable on a laboratory scale prior to our efforts, to a much larger operational level. The task of decomposing already manufactured plastic on such a substantial scale represents a feat that is entirely distinct from merely exploring a theoretical potential by breaking down minute plastic particles within a laboratory setting. The initiation of plastic decomposition was finally brought about by SIITA.

Additionally, SIITA managed to cut down the previously theorized 6-month or longer decomposition period by half, unleashing the potential for globally implementing plastic decomposition. Presently, SIITA continues to push the boundaries of related technologies through innovative advancements, cementing its role as a pioneering force in this field.

Through our exclusive complete decomposition technology, our products undergo a complete decomposition process. The resulting decomposed materials are transformed into organic fertilizer, which is then distributed to local communities and farms, and for the restoration of devastated forests. This embodies the true essence of zero waste, where products, at the end of their lifecycle, return to nature and benefit both the environment and humanity once again.

SIITA’s complete decomposition technology is a technology-intensive innovation, encompassing raw materials, microorganisms, decomposition, and systems. This remarkable achievement by SIITA is recognized for introducing a noble paradigm in response to the continuously escalating environmental challenge. This is primarily due to the fundamental shift we have achieved, where waste is not inherently generated as per our original objective.

SIITA's ultimate goal is to ensure that all consumable products, including those created by SIITA, are not passed on to generations to come, which is why our challenge is still ongoing. Until the issues intertwined with our daily consumption, market dynamics, and society are comprehensively resolved, SIITA's journey of innovation will persist. In September 2021, SIITA disclosed the decomposition technology free of charge, fostering collaboration with relevant institutions and other businesses. SIITA holds a steadfast belief that this decision solidifies our commitment, bringing us closer to our mission of achieving a sustainable and enduring Earth. Moreover, even at this very moment, we take immense pride in walking hand in hand with our customers on our shared path toward realizing 'an enduring Earth.'


SIITA has, thus far, replaced plastic on a scale comparable to that of a World Cup stadium.
To elaborate, a significant island of waste, once destined to float upon the ocean's surface, has now vanished from view.

Within the world exists a biodegradable plastic market valued at 40.9 billion dollars, yet a counterpart market for decomposition remains absent.

SIITA still stands as the sole global enterprise dedicated to plastic decomposition. However, our aspiration extends beyond merely targeting the plastic market. SIITA's goal is to transform the vast trillion-dollar plastic industry into a sustainable ecosystem, even though we may be the last to carry this work to fruition.
