What Happened

India's first green methanol plant is being set up to convert Prosopis juliflora — an invasive weed that has devastated the Banni grasslands of Kutch, Gujarat — into methanol suitable for use as marine fuel.
The project directly addresses two problems simultaneously: ecological restoration of the Banni grasslands by clearing the invasive species, and production of a low-carbon alternative fuel for the shipping industry.
The global shipping industry is under regulatory pressure from the International Maritime Organization (IMO) to adopt green fuels, making demand for green methanol commercially viable.
The initiative exemplifies a circular economy model — converting an environmental liability (invasive biomass) into an economic and industrial resource (marine fuel).
The project involves collaboration between renewable energy and sustainable development firms, leveraging biomass gasification or thermochemical conversion pathways to produce methanol from Prosopis juliflora biomass.

Prosopis juliflora and the Banni Grasslands

Prosopis juliflora, commonly known as "vilayati babool" or "gando bawar" (mad tree in Gujarati), is a thorny shrub native to Mexico, Central America, and northern South America. It was introduced to India in the 1970s by the government for soil stabilisation and as a source of fuelwood in arid regions. However, it rapidly became invasive, outcompeting native vegetation due to its deep root system, drought tolerance, and prolific seed production.

Banni Grasslands: Asia's largest tropical grassland, covering approximately 2,500 sq km in Kutch district, Gujarat; part of the greater Rann of Kutch ecosystem
The Banni was declared a Closed Area (wildlife reserve) in 1955 and is part of the Gulf of Kutch Marine National Park periphery
Home to the Maldhari community — traditional pastoralists whose livelihoods depend on the grassland's native grasses for livestock grazing
Prosopis juliflora has invaded over 80% of the Banni grasslands, drastically reducing fodder availability and biodiversity
The species is listed as one of the world's 100 worst invasive alien species (IUCN)
Other affected species include the Lesser Florican, Indian Wild Ass (Equus hemionus khur), and migratory birds

Connection to this news: Using Prosopis juliflora as industrial feedstock creates an economic incentive to remove it at scale, potentially achieving ecological restoration of the Banni that manual clearance efforts have failed to accomplish.

Green Methanol: Production and Properties

Methanol (CH₃OH) is the simplest alcohol. "Green methanol" refers to methanol produced from renewable or low-carbon feedstocks, distinguishing it from conventional methanol produced from natural gas (via steam methane reforming). There are two main production routes for green methanol: (1) Biomethanol — from biomass (agricultural residues, municipal solid waste, woody biomass) via gasification and catalytic synthesis; (2) E-Methanol — from green hydrogen (electrolysis using renewable electricity) combined with captured CO₂.

The Kutch project uses the biomethanol pathway: Prosopis juliflora biomass → gasification → syngas (CO + H₂) → methanol synthesis
Methanol energy density: approximately 15.6 MJ/litre (compared to diesel at ~34.6 MJ/litre); ships require larger tanks but methanol is safer to store
Methanol is liquid at ambient temperature, making it easier to store and bunker than hydrogen or ammonia
Methanol combustion produces significantly lower SOx, NOx, and particulate emissions compared to heavy fuel oil
Green methanol has a near-zero lifecycle carbon footprint when biomass carbon is considered

Connection to this news: Biomass from the invasive Prosopis juliflora provides a local, low-cost, and carbon-neutral feedstock for methanol production, making the economics of green methanol more competitive.

IMO's 2023 GHG Strategy and Marine Fuel Transition

The International Maritime Organization (IMO) is the United Nations specialised agency responsible for regulating international shipping. In July 2023, the IMO adopted a revised Greenhouse Gas (GHG) Strategy at its 80th Marine Environment Protection Committee (MEPC 80) session. This strategy significantly tightened the 2018 targets.

2023 IMO GHG Strategy target: Net-zero GHG emissions from international shipping "by or around 2050"
Intermediate milestone: At least 20% reduction in GHG intensity of international shipping by 2030 (striving for 30%); at least 70% by 2040 (striving for 80%)
The strategy promotes uptake of zero or near-zero GHG fuels by 2030 and beyond
Approved alternative marine fuels include: LNG (liquefied natural gas), methanol, ammonia, hydrogen, biofuels, and synthetic fuels
Energy Efficiency Existing Ship Index (EEXI) and Carbon Intensity Indicator (CII) are the current regulatory tools, effective from January 2023
The EU's FuelEU Maritime regulation (effective 2025) sets lifecycle GHG intensity limits for marine fuels used in EU waters

Connection to this news: IMO's mandatory decarbonisation targets are creating a large, legally mandated global market for green methanol as a shipping fuel, making India's plant commercially timely.

Circular Economy Principles

The circular economy model contrasts with the traditional linear "take-make-dispose" economy. In a circular economy, waste from one process becomes a resource input for another, extending material lifecycles and reducing resource extraction. Converting invasive biomass to industrial feedstock is a textbook application.

Circular economy is a key theme in India's National Mission for a Green India and the Waste Management Rules (2016)
UN Sustainable Development Goal (SDG) 12 (Responsible Consumption and Production) promotes circular economy approaches
Biomass-to-fuel conversion can align with India's National Biofuel Policy 2018 (amended 2022), which encourages second-generation biofuels from non-food lignocellulosic biomass

Connection to this news: The Kutch project transforms an ecological and economic burden (invasive weed clearance costs) into a revenue-generating industrial input, demonstrating circular economy principles in practice.
