Kevlar is not a renewable material; it is a synthetic fiber made from petrochemicals. The production process involves non-renewable resources, and while it is durable and can be recycled in some contexts, the raw materials used to create it do not come from renewable sources. Therefore, while it has a long lifespan, Kevlar itself is not considered renewable.
Yes, it doesn't automatically regenerate, like water, wind or sunshine.
Yes; the usual route is to take the filament yarn (as it is in bullet proof jackets etc) from woven waste, then chop it down to staple fibre (short fibre in the range of a few mm to hundreds of mm but ideally for most carding operations 30 - 60mm), this staple fibre is then either reprocessed into nonwovens by carding and some form of bonding, it can also be re-spun into staple yarn and woven, alternatively it can be pulped, all these could be used as flexible products or in composites. It does not melt but degrades somewhere around 450°C so can not be recycled that way and as yet is not being re-dissolved for spinning.
The protective plates, depending on the age of it, will be steel, ceramics, or kevlar.
