Dirty Business Evidence Disposal Guide — July 2026 | Dirty Business Wiki

Every product line in Dirty Business creates waste: plant trimmings, metal shavings, misprinted bills, contaminated glassware, failed weapon parts, and packaging residue. Leave it on the floor and heat accumulates—raising scrutiny, triggering events, and eventually endangering your entire operation. Evidence disposal is not a side chore; it is as important as complete orders or grow weed. This guide explains waste types, disposal stations, sweep schedules, and how to build cleanup into production instead of panic-burning after a raid warning.

What Counts as Evidence

If it came from illegal production, assume it counts unless the UI explicitly marks it as inert. Common categories:

• Organic waste — Cannabis stalks, soil, spoiled buds
• Industrial scrap — Weapon filings, broken receivers, oily rags
• Paper and ink waste — Misprints from counterfeiting per production
• Chemical waste — Spills, empty reagent bottles, bad LSD batches
• Packaging trash — Bags, ties, labels tied to traceable SKUs

Dropped items in hallways double as pathing hazards for hire workers and co-op partners. Pick up before you optimize anything else.

Disposal Stations and Upgrades

Bases provide bins, incinerators, acid sinks, or compactors depending on unlock tier. Each station accepts specific waste categories and processes at different speeds. Early bins fill fast during weapon rush nights—invest in throughput via upgrade base before adding a second assembly line.

Place disposal on exit paths from production rooms so workers and players pass them naturally. Hidden disposal rooms fail because nobody walks there mid-sprint.

Upgrade chains may reduce heat per unit or increase batch capacity. Read tooltips when comparing incinerator tiers; cheaper upfront cost is not cheaper heat if burn rate lags output.

Heat and Risk Mechanics

Heat is the abstract pressure meter representing police interest, informants, and forensic trace. Production increases heat; disposal decreases it. Net positive heat over time triggers escalations—patrol frequency, inspections, raids depending on Early Access implementation.

Treat heat like a second bank account:

Session heat budget = expected production heat − planned disposal capacity

If budget goes negative, slow accepts at the order terminal or schedule a disposal sprint before accepting weapon contracts from manufacture weapons.

Exact formulas change in Early Access—monitor updates after patches.

Sweep Schedules That Work

Integrate cleanup into production phases instead of end-of-day marathons:

1. Post-harvest sweep — Grow rooms generate the most volume per minute
2. Post-inspection sweep — Failed quality checks dump scrap immediately
3. Pre-delivery sweep — Staging areas clutter fast during complete orders loading
4. Post-shift co-op sweep — Assign safety officer role from co-op guide

Set a timer every twenty in-game minutes if you lack role discipline. Consistency beats heroic catch-up.

Workers and Automation

Assign janitorial workers to zones with highest trash density—machining first, grow second. Verify they empty full bins; full bins stop accepting waste while production continues, creating floor piles.

Workers do not replace player judgment on chemical waste if special handling is required. Manual dispose hazardous items if icons warn.

Co-op Disposal Etiquette

One player owns safety each session. Others call “scrap” when dropping failures. Never leave co-op mid-disposal sprint without handing off bin status.

Competitive groups race order timers; disciplined groups win streaks because heat never spikes unnoticed.

Product-Specific Tips

Weed: Trim and soil look harmless but stack quickly across multiple harvests. Line bins outside grow rooms.

Weapons: Metal scrap is dense; incinerators may be mandatory. Never stockpile scrap “for later.”

Counterfeiting: Misprints tie to denominations—batch destroy to avoid mismatched evidence trails.

LSD: Glass and solvent waste may need chemical sinks. Running reactions without disposal capacity is how labs blow budgets and heat meters simultaneously.

Cross-reference each chain on production.

Before Raids and Inspection Events

If the game warns of elevated scrutiny:

• Pause nonessential production
• Run full base perimeter pickup
• Empty every bin into final destroyers
• Secure packaged goods in locked storage
• Finish outstanding deliveries to reduce loose product

Panic burns without sorting can waste money if stations reject wrong waste types—learn accept lists early.

Common Mistakes

• Single bin for entire base
• Disposal room off main routes
• Ignoring packaging trash because it “looks small”
• Scaling production without scaling destroy capacity
• Skipping disposal tutorial in demo then importing bad habits to full game

New players: read beginner guide then implement disposal before your second order accept.

Tools and Troubleshooting

Community heat trackers may appear on tools as dataminers publish formulas. For stuck items or non-interacting bins, see controls troubleshooting and verify controls pickup bindings.

Disposal is the difference between a base that runs for weeks and one that collapses from preventable mistakes. Clean floors, low heat, repeat.
