**Table 5.4: Design for Environment Study**
DFE Guideline	Good Aspects of Competitor Product and Ideas for Improvement
0. New Concept Development	Remove fasteners to allow a snap-fit design. Integrate a quiver into the crossbow itself, instead of having it as a separate part. Add a loading mechanism that does not require a very significant force input from the user.
1. Select Low Impact Materials	Crossbow: Aluminum, Fiberglass, Steel Bolt: Aluminum, Carbon Fiber Sling: Nylon, Foam Replace aluminum components with plastic, providing a net benefit for the environment.
2. Reduce Material Amount	Slots in the crossbow body reduce mass Limb is removable to reduce transport volume The "snap-fit" design would reduce material amount by removing the need for fasteners
