Disposal Chest

Disposal chests are chests that will delete any item that is moved into them with a regular hopper. Since they work with hoppers, disposal chests are useful for automatically disposing overflow items in automatic farms, so that the items are not left floating on the ground.

Creating a Disposal Chest

Disposal chests are easy to make, simply LOOK at the chest you would like to turn into a disposal chest and type /disposalchest. When you open the chest you should see that it is named "Disposal" in red text.

Disposal Chest Example

Disposal chests only work as single chests. Double chests do not delete items.

Place a regular hopper that feeds into the Disposal Chest. Any item transferred into a disposal chest by a hopper will be removed instantly upon leaving the hopper.

Pro Tip: Use disposal chests to delete wheat seeds, beetroot seeds and poisonous potatoes for a tidier farming experience.

Farm Overflow Disposal Systems

With chunk hoppers and disposal chests, it is easy to automatically dispose of "overflow" items that do not fit into your linked storage. This is important for minimising server and clientside lag. Add an extra chest to your linked storage chests at the lowest priority and apply filters for items you would like to delete. Place a hopper under it leading into a disposal chest. Once your linked storage chests are full, the items picked up by the crop hopper will go into the new chest, and then into the disposal chest. You may need multiple Disposal Chests to keep up with the production rates of larger farms.

Disposal Chests only work for items transferred by regular hoppers. Items transferred directly into the Disposal Chest by a chunk hopper will not be deleted.

The ideal cheap disposal chest setup - the bottom chest should be your disposal chest, and the 4 top chests should be the ones your chopper(s) link to.

Pro Tip: Remember to add item filters to your chunk hoppers to prevent deleting other dropped items.

Advanced Disposal Tips

The ideal way to set the disposal up for minimal lag would be to have your chests not send items to the disposal until they're full. It minimizes the number of checks needed, since the chest will clear instantly once full. Once the chest is completely full, it will send an item through that should cause the updates we need.

Large farms may experience a problem where, due strictly to rng factors, yield distribution, and timing, a partial stack of one chem gets transferred to a feed chest and the chopper then gets full on another chem, causing the chest to never be completely full and therefore this redstone system to never trigger the feed.

Ways to fix this:

• Add a comparator to each feed chest, and hope that rng lets at least one of them always become full.,
• Add a comparator to each feed chest, and only feed a single type of drop into a feed chest.,
• Create a separate cluster for each type of drop.,
• Add a timer to override it and let it dispose if there's something to dispose of, but accept that the issue can still happen with rng in the short time window.

The above image fixes the repeater delay so item reaches the chest. Then you ideally have each of your choppers linked to the chests, with the one with a repeater being the very last link, so that the other chests can fill up first. The way this works:

• Comparator takes output power from chest and compares it to the output power of the redstone block
• The comparator will only toggle when the output from chest is >= output from redstone block, and since redstone block gives output of 15, we need power level of 15 from chest, which occurs when chest is completely full
• The torch gives inverse of output of comparator (which is what we need)
• Repeater both adds delay and buds the signal to all hoppers (along with a repeater under middle chest to reach back hopper)
