Burn the damn things after chopping them up. Fiberglass burns quite easily. Burn them in a closed environment and use scrubbers to take care of the NO and do not worry about the CO2 which is plant food.
“Burn the damn things after chopping them up.”
Wonder how the tonnage of fiberglass used for wind turbines compares with the tonnage used for other things. Here’s a list from Wikipedia:
DIY bows / youth recurve; longbows
Pole vaulting poles
Equipment handles(Hammers, axes, etc.)
Traffic lights
Ship hulls
Rowing shells and oars
Waterpipes
Helicopter rotor blades
Surfboards,[18] tent poles
Gliders, kit cars, microcars, karts, bodyshells, kayaks, flat roofs, lorries
Pods, domes and architectural features where a light weight is necessary
Auto body parts, and entire auto bodies (e.g. Sabre Sprint, Lotus Elan, Anadol, Reliant, Quantum Quantum Coupé, Chevrolet Corvette and Studebaker Avanti, and DMC DeLorean underbody)
Antenna covers and structures, such as radomes, UHF broadcasting antennas, and pipes used in hex beam antennas for amateur radio communications
FRP tanks and vessels: FRP is used extensively to manufacture chemical equipment and tanks and vessels. BS4994 is a British standard related to this application.
Most commercial velomobiles
Most printed circuit boards consist of alternating layers of copper and fiberglass FR-4
Large commercial wind turbine blades
RF coils used in MRI scanners
Drum Sets
Sub-sea installation protection covers
Reinforcement of asphalt pavement, as a fabric or mesh interlayer between lifts[19]
Helmets and other protective gear used in various sports
Orthopedic casts[20]
Fiberglass grating is used for walkways on ships and oil rigs, and in factories
Fiber-reinforced composite columns
Water slides
sculpture making
Fish ponds or lining cinder block fish ponds.
The odor of burning plastic is unpleasant, so it'll have to be done away from and downwind of human habitation.
