Durability has trade-offs
Silicone products rely on energy and chemical processing, while cured silicone does not readily break down in the environment. The source article highlights both sides: a long-lasting seal may reduce repeat repairs, but the material and manufacturing still have a footprint.
Avoid more material than the joint needs
Measure the joint and choose a cartridge size that matches the work. Use a controlled bead and keep the nozzle sealed between tasks where the product allows it. Preventing an unopened or partly used tube from becoming waste is often the most direct step available to a DIY user.
Dispose according to local guidance
Do not pour uncured product or cleaning residue into drains. Let material cure only if the label and local rules permit that handling, then use the waste route recommended by your council or waste provider. Packaging instructions take priority over general advice.
Use only what the job requires and follow the product label and local waste rules.
