For operational readiness, the SAF maintains a stockpile of ammunition. Some of the ammunition will expire or become unserviceable from time to time. To prevent the build-up of unserviceable ammunition in the inventory as they may present safety concerns, DSTA conducts disposal exercises on a regular basis.

The challenge in the disposal of expired or unserviceable ammunition is in performing the task in a safe and cost-effective manner. In a disposal exercise conducted in 2012, DSTA reduced the disposal cost by S$500,000 through demilitarising ammunition. This is an environmentally friendly disposal method where suitable remnant ammunition scrapes can be salvaged and recycled. Specific items with high recycle value are then shipped in bulk to optimise transport costs, while safety is ensured at all times.

With the long-standing goal of reducing disposal costs to the SAF, DSTA is also exploring the progressive build-up of in-country demilitarisation capability that is environmentally friendly.
