At 11:40 on July 10, 2024, under the supervision of the Public Security Brigade of Dongtou Branch, Wenzhou Public Security Bureau, GN Energetic Blasting safely disposed of a batch of wartime leftover artillery shells adopting the open-pit covered blasting method. This operation represented the first disposal mission after the company signed a strategic cooperation agreement on obsolete explosives disposal with Dongtou Branch Public Security Bureau.

       With rapid social development and evolving public security governance, requirements for hazardous material disposal have become stricter. The management model is shifting from "centralized disposal after batch collection" to "immediate detection and rapid response". Faced with this new landscape, adhering to the principle of safety and efficiency, the company developed and implemented a testing and data monitoring program targeting two major adverse blasting impacts: flying debris and blasting vibration. Monitoring results indicated that flying debris was confined within a 40–50 metre radius around the blasting pit. The vibration velocity measured at the monitoring point 20 metres from the pit stood at merely 0.57 cm/s. The outcome further verified the reliability and technical superiority of the company’s Ministry-level construction method for obsolete explosives disposal via open-pit covered blasting, marking a successful completion of the inaugural disposal task under the strategic cooperation framework.

       Back in 2002, GN Energetic Blasting was designated by Zhejiang Provincial Public Security Department as a recommended service provider for obsolete ammunition disposal. Over the past 20 years, the company has undertaken more than 100 disposal assignments for Zhejiang Provincial Public Security Department, Shanghai authorities and public security organs across Zhejiang Province. It has disposed of over 1,000 artillery shells and tens of millions of rounds of ammunition.Building on extensive practical experience and continuous technological innovation, the company has obtained two Ministry-level construction methods related to explosive disposal, one Science and Technology Progress Award issued by Zhejiang Blasting Industry Association, alongside multiple patents and academic papers. As the lead drafting entity, it formulated the first group standard for the blasting sector in Zhejiang Province, Safety Technical Specifications for Explosives Disposal Operations. Leveraging its robust technical capabilities and adapting to emerging industry demands, the company has evolved from providing one-off services to establishing long-term strategic partnerships, serving as a key strategic partner for public security authorities in explosives disposal.

       Prior to this mission, the company also signed a similar strategic cooperation agreement on obsolete explosives disposal with Cangnan Public Security Branch. Strategic partnerships established across multiple regions reflect regulators’ recognition of our proficient technical capacity and standardized management, as well as expectations for us to lead industry standards and pursue excellence. GN Energetic Blasting will keep refining experience, boosting innovation and strengthening internal capabilities. The company will actively fulfil its social responsibilities and fully support public security authorities in eliminating safety hazards and building a secure community.
