This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,590.

Summary of the Inventive Concept

This inventive concept leverages the core technology of the original patent to develop novel applications for hemp extracts in environmental sustainability, including water pollution treatment, sustainable textiles, agricultural waste reduction, pest control, and biodegradable plastics.

Background and Problem Solved

The original patent focused on the purification processes and methods of manufacture of cannabis extracts for treating mammalian disorders. However, the growing concern for environmental sustainability and the need for eco-friendly solutions create an opportunity to apply this technology to new areas. This inventive concept addresses the limitations of the original patent by exploring the potential of hemp extracts in addressing environmental challenges.

Detailed Description of the Inventive Concept

The inventive concept involves the use of full spectrum hemp extract (FSHE) and broad spectrum hemp extract (BSHE) compositions in various environmental applications. For instance, FSHE can be used to remove pollutants from contaminated water, while BSHE can be incorporated into fabric treatments to enhance durability and water resistance. Additionally, cannabis extracts can be combined with biodegradable polymers to reduce agricultural waste, or used to repel pests and attract beneficial insects in agricultural fields. Furthermore, hemp extract compositions can be used to enhance the biodegradability and reduce the environmental impact of plastics.

Novelty and Inventive Step

The new claims introduce a significant departure from the original patent by applying the core technology to entirely new industries and fields, including environmental sustainability, textiles, agriculture, and plastics. The inventive step lies in the recognition of the potential of hemp extracts to address environmental challenges and the development of novel compositions and methods to achieve this.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different types of cannabis extracts, such as CBD-rich or THC-rich extracts, or the development of new methods for incorporating hemp extracts into textiles, plastics, or agricultural applications. Variations of the inventive concept could also involve the use of hemp extracts in combination with other sustainable materials or technologies.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including environmental remediation, sustainable textiles, agriculture, and plastics. The market for eco-friendly solutions is growing rapidly, and the use of hemp extracts in these applications could provide a competitive advantage for companies seeking to reduce their environmental footprint.
