The remains of a CRPF vehicle after it was blown up by a Naxal IED, killing seven policemen. The culprit: ammonium nitrate
New ‘non-explosive’ technology could replace TNT, ammonium nitrate

Besides the 24 people killed and 130 injured in this month’s Mumbai bomb blasts, this year has already witnessed another 266 Indians killed or injured in 76 explosions set off by Kashmiri, Naxal and Assamese militant groups. The Ministry of Home Affairs (MoHA) admits that most of these attacks feature easily available explosives --- like TNT, dynamite, slurry and the deadly ammonium nitrate-fuel oil mixture (ANFO) --- that were stolen by militants. Yesterday, the Home Ministry (MoHA) clamped down on the availability of ammonium nitrate, declaring it an explosive under the Explosive Act of 1884.

But New Delhi bureaucrats continue to block a revolutionary new non-explosive material that would take those “old-style” explosives out of circulation.
This new, game-changing product, called Green Break Technology, does the same job as traditional explosives like ANFO: splitting open rocks, bringing down buildings and making tunnels through mountains. Unlike traditional explosives, though, Green Break Technology (or GBT) cannot be made into bombs since it cannot be detonated or exploded. That makes it useless for terrorist products like exploding suitcases, car bombs and improvised explosive devices (IEDs).
The secret of GBT’s non-lethality is that it burns relatively slowly. Conventional explosives, like TNT, dynamite and ANFO burn at 1000-3000 metres per second, producing devastating shock waves that send splinters or shrapnel flying hundreds of metres. In contrast GBT does not explode when it is ignited; instead, it reacts chemically, releasing a large amount of harmless gas. This gas rapidly builds up inside, say, a rock, exerting outward pressure and fracturing it within milliseconds. Since GBT burns far slower than explosives, there is no lethal shock wave and no splinters shooting outwards. The broken chunks of rock fall harmlessly just 5-10 metres from where the GBT cartridge is ignited. The shock wave cannot even break a windowpane, far less blow up a security force vehicle or kill patrolling jawans.
In international testing, in accordance with “UN Recommendations on the Transport of Dangerous Goods; Manual of Tests and Criteria”, GBT has been placed in “Division 1.4”, the same category as a car airbag, reserved for “Substances and articles which present no significant hazard.” This allows GBT cartridges to be safely transported even in passenger airliners, without police escort. GBT is being flown into India on Qatar Airways commercial flights for demonstrations that have been requested by Delhi Metro Rail Corporation; Defence R&D Organisation (DRDO); Border Roads Organisation; Mazagon Dock Ltd; and the Border Security Force, amongst others.
Green Break Technology Ltd, South Africa, which holds a global patent for GBT, plans to develop a global supply hub in India, from where it could export 4-6 million GBT cartridges every month. It has licensed an Indian company, Eco Breaking Technologies India Pvt Ltd (EBT India), a part of the Alchemist Group, to manufacture GBT cartridges at a factory near Alwar, Rajasthan. But the government has stymied this plan.
Last December, EBT India applied to the Dept of Industrial Policy and Promotion for an industrial licence. Within days, the DIPP asked the MoHA and the MoD for their views. But the MoHA, the key agency in approving this manufacture, has sat on this application for the last seven months.
In a telephone call with Business Standard, Utthan Kumar Bansal, the MoHA’s Special Secretary for Internal Security, flatly rejected a request for comments. “You have no locus (standi) for seeking information on this highly confidential matter”, said Bansal.
Josy Cohen, the South African chief of Green Break Technology Ltd, points out that official foot-dragging in India contrasts with the enormous interest in GBT overseas. “From the technological viewpoint, GBT is a major breakthrough, the longstanding dream of experts in infrastructure demolition; underwater applications; and even mining,” says Cohen.
According to Cohen, GBT’s greatest advantage is its eco-friendly nature. The gases produced when GBT burns are harmless nitrogen, carbon dioxide and water vapour. Since none of these are combustible, GBT is ideal for underground mines, where pockets of inflammable methane gas render conventional explosives unusable. And GBT is ideal for underwater use, since there is no shock wave that kills marine life. This gentleness remains GBT’s only drawback, since it cannot be used for heavy duty “primary blasting”.
MoHA officials admit that the lack of regulation of factories manufacturing traditional explosives like slurry and ANFO permits the diversion of large quantities of explosives from legitimate users, especially road builders. Last August, the media extensively reported that 300 tonnes of explosives, manufactured by Rajasthan Explosives and Chemicals Ltd (RECL) went missing. At the same time, there is no precedent for licensing a radically new product like GBT. Since the MoHA and the DIPP are unwilling to accept international testing results, and they remain unwilling to arrange their own testing, EBT India’s request for an industrial licence continues to languish.
