Impact of Product After Useful Life:
Generally, this product would have a long useful life, and would be a piece that one could keep and repurpose many times before needing to throw out or find a new home
Impact of product being thrown away is an addition to landfills, as it is often disposed of with normal trash
Other end-of-life for wood is often burning, either to get rid of or sometimes for power/heat purposes
This ends up increasing overall carbon emissions and is actually a worse alternative in terms of environmental impact
If the product was made from a material other than wood, such as plastic, then it would be more difficult to dispose of it without causing it to build up in landfills
Improper disposal of e-waste can have many strong adverse environmental effects
Solutions to Hazards:
According to many sources including the one below, the optimal end-of-life for wood is having it recycled. If this is not an option, the best alternative is a landfill.
Some alternate materials for shelving, such as certain types of plastics, may also be recyclable
The article below suggests that an option that could take care of some wood waste is converting it to coal with lower sulfur concentration than average coal as it can help reduce carbon emissions
Ideally, the product being made would be high enough quality that it would stay in usable condition until the user no longer wanted it and it could then be repurposed or given away - society overall seems to be moving towards recycling by any means necessary instead of throwing into landfills, so if the product is made well enough, negative social implications would be minimal
Collection and/or proper disposal of electronics:
Inform the customer about where to send electronics after they fail
Collect electronics from consumer to repurpose working parts in new products
If user wants to continue using product, allow for repair of broken components instead of replacing the entire system
