Hi, hope everyone is keeping well under lockdown? It's been a while since I posted on here but have a disposal question. I have a load of old spent fireworks to dispose of. Probably about 20 odd cat2/3 that have all been fired and been dumped in my greenhouse for at least 2 years. I have a skip coming this weekend. Can I just throw the firework carcasses into the skip or should I check with the skip company first tha they're happy to take them?
