This introduces and analyzes the Saga Green Agri Valley initiative in Japan, which redefines carbon dioxide from a pollutant into a valuable, sustainable resource.

This plan centers on transforming a local incineration plant, typically viewed as a nuisance, into an industrial hub by capturing high-purity CO2 and waste heat. The captured resources are then used to support a cluster of high-value businesses, including controlled-environment agriculture, algae cultivation, and aquaculture, attracting diverse corporations like Kao and Kumagai Gumi.

It uses this case study as a lesson in marketing and value creation, showing how strategic re-framing and the targeting of companies that require CO2 for growth have generated significant economic impact and positioned Saga as a leader in green transformation (GX). The initiative demonstrates how converting a "negative asset" into a sustainable resource can create new markets and generate organic synergies among participating businesses.
