TECHNICAL DESTRUCTION OPTIONS: 

TECHNICAL DESTRUCTION OPTIONS

SALW destruction: 

SALW destruction Many differing technologies and techniques. Selection of most suitable technology depends primarily on: Finance / Donor Resource Mobilisation Condition of stockpile In country capacity Environmental legislation

Destruction Procedures & Technologies - Weapons: 

Destruction Procedures & Technologies - Weapons Type of Weapons Quantity of Weapons Resources & Technologies Financial Considerations Security Constraints Final Disposal Methods

Open Detonation: 

Open Detonation

Open detonation: 

Open detonation Advantages High production rates Low cost Limited final processing Disadvantages Environmental impact Noise pollution Logistic disposal experience limited Risk of “kick out” Daylight operations only No recycling value

Open Burning Technique: 

Open Burning Technique

Open Burning: 

Open Burning Advantages High production rates Low cost Little disposal experience Limited final processing recycling value Disadvantages Environmental impact Daylight operations only Only certain natures

Industrial demilitarisation: 

Industrial demilitarisation Advantages: Mechanical disassembly Environmentally controlled incineration 24/7 capacity Low operating costs Possibility to recover materials Disadvantages: High capital costs May be beyond local available resources

Demilitarisation processes: 

Demilitarisation processes National Legislation Chemistry of Ammunition Knowledge of Ammunition Design Qty for Disposal Financial Final Destruction Options

Pre-processing operations: 

Pre-processing operations Manual disassembly Advantages Limited capital investment required Disadvantages Labour intensive Requires well trained, semi-skilled staff Production rates can be low

Pre-processing operations: 

Pre-processing operations Mechanical disassembly Advantages High production rates Limited staff requirement Environmentally benign Disadvantages High capital investment Design limited to certain types of APM

Pre-processing operations: 

Pre-processing operations Robotic disassembly Similar to mechanical disassembly, but capital costs are higher Mechanical breakdown Only really suitable for the exposure of explosive fillings in the case of APM

Cryofracture: 

Cryofracture Advantages Environmentally benign Low staff requirements Relatively low capital investment Disadvantages High operating costs for liquid nitrogen Few proven production systems Variable “shear force” requirements

Cryofracture: 

Cryofracture

Hydro abrasive cutting: 

Hydro abrasive cutting Advantages Low staff requirements Wide range of APM type can be processed Disadvantages High capital costs “Grit sensitised” explosive Requirement for waste-water PCS

Hydro abrasive cutting: 

Hydro abrasive cutting

Incineration: 

Incineration Rotary kiln Plasma arc Car bottom furnace

Plasma arc incineration: 

Plasma arc incineration

Plasma arc incineration: 

Plasma arc incineration Advantages Extreme operating temperature Lower emissions than other incineration systems Simpler PCS requirements Disadvantages High capital investment High operating costs for electricity, but comparable with rotary kiln

Rotary kiln incineration: 

Rotary kiln incineration

Rotary kiln incineration: 

Rotary kiln incineration Advantages Most mature, therefore proven technology Low staff requirement Disadvantages High capital investment Variable feed rate requirements Requires integral PCS

Contained detonation: 

Contained detonation

Contained detonation : 

Contained detonation Advantages Limited pre-processing requirements Disadvantages NEQ limited Potentially expensive in donor charges
