Program name

Deep-Tech Startups Support Program in the Green Transformation field

Business Plan

By utilizing technology to produce 100% natural and biodegradable superabsorbent polymers from crop residues, we aim to support farmers suffering from droughts and achieve sustainable agriculture. We also support the green transformation (GX) initiatives of companies which are producing chemical polymers and/or products with chemical polymers as their product's raw materials.

Research Outline

This research and development aims to enable the production of a new superabsorbent polymer (biopolymer, BP) from domestic raw materials, different from the existing superabsorbent polymer (EFP) made from pectin, thereby achieving a multi-site and resource recycling model for superabsorbent polymers that are completely organic and fully biodegradable. Additionally, with an eye towards the dissemination of the BP developed through this research and development, investigations and studies will be conducted in collaboration with domestic and international partners to establish optimal usage methods in agricultural land, in addition to upgrading existing EFP and establishing new applications.
