Scrap Wood in Project Zomboid (Build 42.19): Fuel, Carving, Charcoal

Build 42.19 · Scrap Wood · fuel, carving handles, small charcoal

Quick answer Scrap Wood (in-game name for Unusable Wood) weighs 1.0 and burns for 1.4 in-game hours as fire fuel. It is not fuel-only: with Carving 1 you can carve it into Small Handles, and charcoal kilns accept it as small wood feedstock. Maximum loadable fire fuel is a sandbox option (8 hours on Apocalypse / Rising / Extinction, 12 hours on Outbreak)—not a single fixed “B42 = 8h” rule.

Item identity and stats

In-game name: Scrap Wood

Also known as: Unusable Wood (internal / older English)

Older guides sometimes invent “ScrapWood” as a separate item. In current vanilla, Scrap Wood and Unusable Wood are the same piece of junk wood.

Property	Build 42.19 value	Notes
Weight	1.0	Not 0.5–0.7. Ten pieces = 10 weight.
Category	Junk	Still a byproduct item, not a construction plank.
Fire fuel	1.4 hours per piece	Counts as wood fire fuel in campfires, stoves, and similar.
Charcoal kiln	Small wood batch	Eligible for Make Wood Charcoal Small (see below).
Barricade / planks	No	Cannot replace Planks on windows/doors or in Woodwork builds.

What Scrap Wood can do

In current vanilla, Scrap Wood has three practical roles. It is not “only good for fires.”

1. Fire fuel

Add to campfires, wood stoves, fireplaces, charcoal barbecues, and other fire containers that accept wood fuel.
Each piece adds 1 hour 24 minutes of burn time.
It is fuel, not tinder. You still need a lighter, matches, or a valid tinder/starter combo to light a dead fire.

2. Carve Small Handles

Recipe: Carve 2 Small Handles.
Requires Carving 1.
Inputs: 1 Scrap Wood (or several other broken wood pieces) + a kept sharp knife or meat cleaver.
Output: 2× Small Handle.
Awards Carving XP.

3. Small wood charcoal

Recipe: Make Wood Charcoal Small (kiln / charcoal station).
Consumes 18 small wood pieces (Scrap Wood qualifies).
Outputs 12× Charcoal Crafted.
Useful when you already run a charcoal kiln and have scrap piles left from base cleanup.

What it still cannot do

No vanilla “4 scrap → 1 plank” recipe.
No barricading or wall/floor builds.
Not a compost ingredient in vanilla (that would require a mod).

Priority tip Early game, burning scrap for water/food is still the default. Once you have Carving 1 and a sharp knife, convert spare scrap into Small Handles before you fill every fire to the sandbox cap. Save planks and logs for building whenever you can.

Fire fuel and efficiency

Burn time is in-game hours. “Hours per weight” is burn hours ÷ inventory weight—handy when you care about bag space, not just pile size.

Fuel item	Burn time	Weight	Hours per weight
Scrap Wood	1.4 h	1.0	1.40
Plank	2.0 h	3.0	0.67
Log	6.0 h	9.0	0.67
Tree Branch	1.0 h	2.0	0.50
Twigs	0.25 h (15 m)	0.2	1.25
Ripped Sheets	~0.083 h (5 m)	0.1	0.83

Scrap Wood is still a strong portable fuel by weight—better than planks or logs—but the old claim of “~0.5 weight and ~1h50m per weight” was wrong. With weight 1.0, six scraps weigh 6 and give 8.4 hours of fire; one log weighs 9 and gives 6 hours.

When to burn what

Scrap Wood: short–medium fires, cooking, boiling water, overnight stove heat when you already have piles from dismantling.
Planks: longer burns only if you have surplus; planks are also structural materials.
Logs: long base fires when you can haul them; worst hours-per-weight of the three wood fuels listed above.
Paper / sheets / twigs: tinder or emergency micro-burns, not main heat stockpiles.

Maximum fire fuel hours by preset

Build 42 does not hard-code a single universal “8-hour scrap limit.” Campfires, wood stoves, and similar containers honor the sandbox option Maximum Fire Fuel Hours: the maximum hours of fuel you can place in a fire at once.

Sandbox preset	Max fire fuel hours
Apocalypse	8
Rising	8
Extinction	8
Outbreak	12
Custom sandbox	Whatever you set in the option

Practical impact On an 8-hour cap, about 5 full Scrap Wood (5 × 1.4 = 7.0 h) fit before the next piece is blocked; a 6th piece would need remaining capacity. On Outbreak’s 12-hour cap you can load more. Fill before sleep, then re-check remaining fuel after long rests. Outdoor campfires can still be affected by rain; indoor stoves and fireplaces are safer heat sources.

How you get Scrap Wood

Dismantling wooden furniture / moveables: low Woodwork skill and failed scrap checks produce more scrap instead of clean planks or parts.
Broken wood pieces and traps: destroyed traps and some break results leave scrap wood.
World loot / bins / foraging trash: appears as junk in several containers and as a forage trash entry.

Raising Woodwork (Carpentry) improves salvage quality so you get more planks and fewer scrap piles. Scrap itself is not a failure state anymore if you plan carving or charcoal runs.

Common mistakes

Claim	Current Build 42.19 reality
“Scrap Wood is fuel only; no crafting.”	False. Carving Small Handles and the small charcoal kiln batch are vanilla uses.
“Weight is ~0.5–0.7.”	False. Weight is 1.0.
“B42 always caps fire fuel at 8 hours.”	Incomplete. Depends on Maximum Fire Fuel Hours (8 on several presets, 12 on Outbreak, custom otherwise).
“Scrap Wood and Unusable Wood are different items.”	False in current English UI. Display name is Scrap Wood; older / internal wording still says Unusable Wood.
“You can barricade with scrap.”	False. Still needs planks or metal sheets.

Workshop mods that convert scrap into planks or compost may still exist, but they are not vanilla. Check Build 42.19 tags and save compatibility before you rely on them. This page only documents vanilla behavior.

Practical checklist

Store scrap near a stove or kiln; weight is 1.0 each, so do not over-pack long scavenges.
Burn scrap first when you need heat and still need planks for fortification.
At Carving 1, convert spare scrap into Small Handles before overflowing storage.
If you run a charcoal kiln, batch 18 small wood pieces (including scrap) for 12 crafted charcoal.
Check your world’s Maximum Fire Fuel Hours in sandbox options—do not assume 8 hours on every save.
Keep fires clear of flammable clutter; extinguish when leaving if you cannot supervise them.

Numbers at a glance

Weight: 1.0 per piece
Burn time: 1.4 hours (1 h 24 m) per piece
Carving: Carve 2 Small Handles at Carving 1 (1 scrap → 2 handles)
Charcoal: 18 small wood → 12 Charcoal Crafted
Fire fuel cap: 8 h (Apocalypse / Rising / Extinction), 12 h (Outbreak), or custom

Bottom line Scrap Wood is still excellent campfire fodder, but in Build 42.19 it is also a Carving input and a small-charcoal feedstock. Treat it as a multi-use junk material with accurate stats: weight 1.0, 1.4 h fuel, and a sandbox-driven fuel cap—not a pure trash item with a universal 8-hour rule.
