Environmental Assessment of Ammunition: the Importance of a Life‐Cycle Approach

Abstract

Environmental research related with military actions has been focused on the monitoring of contaminants from live‐fire training and munitions disposal. It is important to take a further step and use this information to assess the environmental impacts of this contamination. In addition, it is relevant to assess the consequences of using different alternatives in a life‐cycle perspective to avoid unexpected problems, and assess the hotspots of ammunition manufacturing in order to decrease the impacts in terms of other types of environmental burdens. The Life‐Cycle Assessment (LCA) methodology can be employed to quantitatively assess the environmental impacts associated with munitions. LCA can assist the decision makers in answering some questions: are “green“ ammunitions presenting lower environmental impacts than standard ones? What should be done to improve the performance of ammunitions from an environmental point of view? The aim of this paper is to demonstrate the importance of assessing the impacts of ammunitions in a life‐cycle perspective and highlight the main environmental concerns. Three applications of LCA are presented: the production and use of generic large calibre ammunition; the comparison of the production and use of four types of small calibre ammunitions; the assessment of two technologies for ammunition disposal. The conclusions drawn can aid in providing tailored and supported decisions in order to decrease the impacts of ammunitions in a life‐cycle perspective

Security Challenges and Air Quality Management in India: Emissions Inventory and Forecasting Estimates

“…Ahmed et al [64] concluded that economic growth played a vital role in reducing military arms transfers and carbon emissions and encouraged efficient energy investment to achieve green developmental objectives worldwide. Ferreira et al [65] argued whether green ammunition lowers environmental challenges to reduce economic sufferings? The lifecycle assessment of warheads emphasized concentrating on production and assessment of ammunition technologies to lower environmental concerns.…”

Synthesis and Energetic Properties of Trending Metal‐Free Potential Green Primary Explosives: A Review

“…[23] To the development of novel promising primaries, which not only requests free from toxic metals but also chemically and thermally stable, better performance, reasonably sensitive, and safe to synthesized. [33] Based on these reasons, synthesis of novel promising metal-free greener primary explosives (consists of only CHON elements) with high performance is required to substitute the LA and LS. [34] Therefore, this paper needs to summarize the latest developments in the synthesis and characterization of various metal-free green primary explosives.…”

“…In the past, DDNP and GNGT were considered metal‐free primary explosives, but GNGT exhibits poor pressure resistance and are eliminated from practical applications, while DDNP has major drawbacks such as photosensitivity, high sensitivity to friction, and impact [23] . To the development of novel promising primaries, which not only requests free from toxic metals but also chemically and thermally stable, better performance, reasonably sensitive, and safe to synthesized [33] . Based on these reasons, synthesis of novel promising metal‐free greener primary explosives (consists of only CHON elements) with high performance is required to substitute the LA and LS [34] .…”

Decision Framework for the environmental management of explosive contaminated land

“…Both the manufacturers and users of explosives are responsible for any adverse impacts on the environment from explosives by legislation such as the Contaminated Land (England) Regulations 2006 (2), Water Resources Act 1991 (3) and the Environmental Permitting Regulations 2010 (4). Therefore, environmental management systems such as ISO14001 and other environmental assessment tools such as lifecycle analysis (ISO140040) have become a ubiquitous way for organisations to ensure compliance with environmental legislation, and mitigate or minimise their environmental impact through life (5)(6)(7). This is equally true for private business and government organisations, where bespoke management systems have been developed (8).…”

“…Adverse impact on the environment from explosive manufacturing and training activities is usually determined by a qualitative process such as environmental impact prioritisation, in which a matrix is used to prioritise significant impacts based on the likelihood and severity (7)(8)(9). The aim of the prioritisation is to indicate the likely significant environmental impacts of an organisation's activities, and highlight where mitigation of adverse impacts is required (10).…”
