Benefits of technology

This patented new type biological package (BSP), made up from special types of plastic, can be used at home, restaurant, commercial facility, recreational facilities, public health care institutions, military bases, hospitals, homes, offices, and anywhere where heavy metallic wastes may occur due to their disposal needs. It provides an effective way to fix enzymases onto this packaging material without losing them during storage. Overall, BSP offers improved safety, durability, flexibility, ease of handling, versatility, and stable performance over time.

Problems solved by technology

This patented describes various ways to improve environment quality through combining different types of enzygene molecules (EnvBM). These techniques involve creation of hybrid enzymatic systems called Envirobiosynthesis Bound Microcavengers (EBMC), which consist mainly of hydrophilic polymer particles carrying enzymatically active sites. By doing this combination between these two components, the EMBL process becomes effective at treating harmful substances such as pesrotoxic compounds and heavy metals while maintaining its original function overtime. Additionally, the patents discuss how immobilizable enzymators may be mixed together with silica solids or glass microspheres to increase durability against heat stress and humid conditions during manufacturing and usage periods.
