CF grades require slightly higher temperatures and pressures. Very abrasive → carbide tooling is mandatory. Almost isotropic shrinkage is very low. Electrical conductivity must be taken into account in the design of parts.
ABS is recyclable (code 7). It can be remelted and re-injected several times with slight degradation of its properties. Industrial recycling channels exist for production waste. End-of-life recycling remains limited by selective collection.
Standard ABS is not certified for food contact. Special ABS-FDA grades exist but remain marginal. Prefer PP, PE, or PETG for common food applications.
