A complete dependency-ordered system for maintaining mechanical agricultural capability and bootstrapping an industrial material base from raw inputs: wood, stone, shell, clay, sulfur minerals, oilseed crops, animal products, and labor.
Everything starts from stuff you can dig up, cut down, or find in waste.
PHASE 0: STOCKPILE (pre-disaster)
|
v
PHASE 1: FIRE AND ALKALI
kiln -> lime (from shell/marl) -> slaked lime
kiln -> pearl ash (from hardwood) --------+
slaked lime + pearl ash -> KOH -----------+-> saponification -> fuel

These items cannot be fabricated from scratch or require industrial infrastructure that will not exist. Acquire and store them now.
| Item | Reason | Storage Notes |
|---|---|---|
| Hemp seed | Entire fiber/oil/carbon economy depends on it | Sealed, cool, dry. Viable 3-5 years. One plant = thousands of seeds. |
| TKS dandelion seed (Taraxacum kok-saghyz) | Only temperate-climate rubber source | Same storage as hemp. Source from seed banks or research institutions. |
| NaCl (rock salt) | Soap hardening, food preservation, HCl production | Bulk. Sealed barrels. Indefinite shelf life. |
| Steel wire (all gauges) | Tire reinforcement, binding, building, fabrication | Coated in grease/tallow, wrapped, dry storage. Especially fine gauge. |
| Copper tubing | Condensers, distillation worms, fuel lines | Sealed ends, dry. Reserve for thermal/electrical use only. |
| IMT 533/539 spare parts | Injector nozzles, piston rings, valve springs, gaskets, bearings | Greased, wrapped, sealed. These are the consumables. |
| Hand tools | Files, draw plates, taps and dies, chisels, punches | Oiled. A draw plate is an entire wire industry. |
| Castor seed (Ricinus communis) | Fuel, chemical feedstock, pest/predator control | Viable 2-3 years sealed. Grows invasively once established. |
The foundation of everything. Without alkali (KOH) and acid (H2SO4), no fuel processing, no soap, no fertilizer, no glass, no concrete.
Build first. Stone or brick construction. One firing serves multiple purposes in different zones or sequential batches.
| Zone/Batch | Temperature | Input | Output |
|---|---|---|---|
| Lime burning | 900-1000C | Mussel shells, snail shells, eggshells, marl, tufa | Quicklime (CaO) |
| Pearl ash calcination | 700-900C | Black salts (evaporated wood ash lye) | Pearl ash (K2CO3) |
| Metakaolin | 600-800C | Kaolinite clay | Reactive aluminosilicate (for Phase 3) |
Fuel: hardwood charcoal with forced draft (bellows). Charcoal from the same hardwood used for ash production. The tree does double duty.
River unionid mussels. Shells are 94-95% CaCO3. Collect from riverbanks. An afternoon's labor yields kilograms of shell.
Calcine at 900C: CaCO3 -> CaO + CO2
Also viable: land snail shells (Helix, Cepaea), eggshells (if keeping poultry), tufa/travertine deposits at spring emergence points.
Marl is 35-65% clay mixed with 35-65% CaCO3. Found in river valleys, lake beds, post-glacial sediments, under peat bogs.
Field identification:
Weak fizzing = mostly clay. Select material that fizzes vigorously.
Where to look:
Refining marl to lime:
clay. Crude beneficiation by hand improves product.
stays as hard chunks. Sieve to separate.
For cement-like product: skip separation. Calcined marl is natural cement clinker. Grind fine. (But geopolymer is preferred — see Phase 3.)
with fresh ash to concentrate. The filtrate is lye.
mass with carbon impurities).
Carbon burns off. Product is pearl ash: predominantly K2CO3 with some KCl and Na2CO3.
Dissolve pearl ash in water. Add slaked lime (Ca(OH)2). Stir.
K2CO3 (aq) + Ca(OH)2 (s) -> CaCO3 (s) + 2 KOH (aq)
CaCO3 precipitates. Filter through cloth. Filtrate is KOH solution (80-90% conversion efficiency).
Closed loop: The CaCO3 precipitate goes back into the lime kiln to regenerate CaO. Calcium cycles indefinitely.
Source: Native sulfur from volcanic deposits, or roast pyrite (FeS2) found in clay, shale, and many sedimentary formations. Pyrite looks like brass-yellow metallic cubes in rock.
Burning:
(Iron oxide byproduct: pigment, polishing compound)
Acid production (simple method): Burn sulfur in a stone/clay chamber. Pass fumes through a packed column of broken pottery with water trickling down. Yields dilute sulfurous acid (H2SO3) which slowly oxidizes to H2SO4 in air. Slow but requires no lead.
Acid production (lead chamber method): If lead sheet is available (scavenged batteries), line wooden chambers. Burn sulfur, inject steam and saltpeter (KNO3) fumes. The nitrogen oxides catalyze oxidation of SO2 to SO3, which combines with water to yield 60-70% H2SO4.
Crops (in priority order):
biofumigant seed cake, meat preservative
Equipment: Screw press. Hardwood frame, iron screw. Can be fabricated by a blacksmith. Driven by hand initially, by IMT PTO later.
Oil is pressed, settled, filtered through cloth. Crude oil is the input to fuel processing (Phase 2).
2 KOH + H2SO4 -> K2SO4 + 2 H2O
Or directly from pearl ash:
K2CO3 + H2SO4 -> K2SO4 + H2O + CO2
K2SO4 is the preferred potassium fertilizer. Unlike KCl, it does not damage soil microflora. Apply to mustard, sunflower, hemp, and castor crops to close the nutrient loop.
Depends on: Phase 1 (KOH, H2SO4, lime, oil pressing).
The IMT 533 (33 hp, 3-cyl diesel) and IMT 539 (39 hp, 3-cyl diesel, 2.5L) are the target machines. Fully mechanical fuel injection, mechanical steering, no ECU, no glow plugs, no electronic fuel management. Once running, zero electrical components are needed for combustion. Start by hand crank or tow-start in gear.
Engines rated for 20,000 hours before overhaul.
Simplest. Filter and dewater crude pressed oil. Run a two-tank system:
around exhaust manifold for preheating)
Yugoslav farmers already ran these engines on cooking oil.
Saponify oil with KOH, then crack the soap with H2SO4:
Fat + 3 KOH -> 3 potassium soap + glycerol Potassium soap + H2SO4 -> free fatty acids + K2SO4
Fatty acids (nonpolar) float on top. Decant. Dewater by gentle heating under a vented wooden lid, or pass through a column of calcined gypsum (heat natural gypsum to 150C to dehydrate: CaSO4-2H2O -> CaSO4). Target < 0.05% water.
Blend 70/30 fatty acid/turpentine. This runs cleanly in the IMT mechanical injector pump.
Byproducts:
glycerol syrup remains
Castor oil burns well for heating distillation, calcination, and other thermal processes where varnish formation is irrelevant. Reserve for non-engine combustion. The polymerized varnish residue (scraped from any surface it contacts) dissolves in turpentine to produce a natural lacquer coating for wood and metal.
Feedstock: Ruminant tallow (beef, mutton, goat). Saturated fats (palmitic, stearic acid) produce the hardest, longest-lasting bars.
Process:
separate from water. Repeat for cleaner product.
potassium in the fatty acid salt. Hard soap precipitates.
Byproduct: KCl in solution.
KCl is harmful to soil microflora. Do not use as fertilizer. Convert:
2 KCl + H2SO4 -> K2SO4 + 2 HCl (gas)
Capture HCl by bubbling gas through water. Uses for HCl:
K2SO4 goes back to the fields.
Storage: Hard soap bars in wax/turpentine-sealed wooden barrels. Stable indefinitely. Stockpile in bulk — a ton is not unreasonable.
Sodium conservation: Sodium leaves the system in wash water. In practice, the loss rate per person per year is small. Route wash water through evaporation ponds to recover some. A bulk NaCl stockpile (Phase 0) covers decades of soap production.
Score living pines (Pinus nigra, P. sylvestris). Collect resin in clay cups over weeks.
Distillation: Heat collected resin in a sealed copper or clay pot with a condensing tube (coiled copper through a water-filled jacket). Turpentine distils at 150-180C. Rosin remains as hard amber solid in the pot.
Turpentine uses:
Rosin uses:
paste)
Not optional. Infrastructure. Target: 10 hives minimum.
Products per colony per year:
mead)
Beeswax/turpentine polish: Mix 1:3 to 1:4 wax:turpentine by volume. Penetrating wood finish applied after rosin treatment.
Wood treatment protocol (handles, shafts, structural timber):
linen or hemp cord soaked in rosin before wax coat. Bonds permanently, adds shock absorption and grip.
Result: wood items lasting hundreds of years.
Ricinus communis. Grows aggressively in any frost-free period above 15C. Self-seeding, invasive. This is a feature.
Products:
- Rodenticide - Predator bait (jackals, feral cats, wolves) - After detoxification (sustained heating 80C+ for 30 min): high-nitrogen fertilizer
Not castor oil (reserve for fuel/chemical use). Instead:
Mustard oil (high erucic acid = strong film strength) + small addition of beeswax dissolved in turpentine as viscosity modifier and anti-wear agent.
Mustard oil tolerates the IMT's large clearances. Plan for periodic decoking (remove head, scrape deposits) every 200-500 hours. Straightforward on a 3-cylinder mechanical diesel.
Depends on: Phase 1 (lime, pearl ash, KOH), Phase 2 (turpentine, engine running, wood treatment).
Ingredients (all locally sourced):
This is the classic forest glass (Waldglas) formula. Central European glassworks used this for centuries.
Equipment: Clay crucible in a bellows-driven charcoal furnace. Melt at 1100-1200C. Blow on an iron pipe or cast in clay molds. Optical quality not needed — crude greenish vessels are sufficient for chemical work. Broken glass goes back into the crucible.
Products:
Process (Glauber, 1646): Fuse pearl ash (K2CO3) with fine silica sand in a crucible at 1100-1200C. CO2 boils off. When bubbling ceases, the reaction is complete. Cool. Grind the glassy mass to powder. Expose to moist air or dissolve in water. The result is potassium waterglass — a viscous alkaline silicate solution.
Made in the same crucible furnace as glass vessels. One firing session, two product streams.
Advantages over Portland cement:
cycling)
Recipe:
Dehydroxylates the crystal structure, creating reactive amorphous aluminosilicate.
Applications:
Note: Potassium-activated geopolymers have better workability and lower efflorescence than sodium-activated ones. The K pathway from wood ash is preferred.
Process:
Yield: ~18% by mass. Carbon content ~88%.
Driven-off volatiles (capture these):
Use in construction: Lay carbon fiber bundles into geopolymer or concrete pours as directional reinforcement, same as rebar placement. For thin panels, layer like fiberglass with geopolymer as matrix.
Advantages over steel rebar:
Primary structural method. Dry stone or lime-mortared.
Properties:
Combined with hempcrete insulation: Hemp hurd (woody core) mixed with lime binder (mussel-shell lime) = hempcrete. Lightweight insulating infill. Not structural alone, but excellent between timber framing or as interior render on stone walls. Thermal mass (stone) outside, insulation (hempcrete) inside.
Stone-lined subterranean chambers for engine, forge, and chemical operations.
Advantages:
dramatically quieter than surface operation)
Ventilation: Stone-lined shafts with natural draft. Engine exhaust heat rises through exhaust shaft, draws cool air in through intake shaft. The engine itself drives the draft.
Source: Goat and donkey hides (both working animals with end-of-life harvest value).
Vegetable tanning: Oak or chestnut bark tannins. Soak hides in tannin liquor for weeks to months. HCl (from KCl + H2SO4, Phase 2) used for unhairing.
Leather products:
after cutting to shape
beeswax
Glycerol treatment: Apply crude glycerol to tanned leather to maintain flexibility. Glycerol penetrates collagen matrix better than tallow (which sits on the surface). Follow with thin linseed oil coat for water barrier. Critical for gaskets and seals subject to heat cycling.
Gelatin production: Boil hides, hooves, bones. Filter. The gelatin solution, mixed with glycerol at 20-30% by weight before casting, produces flexible tough films.
Gelatin products:
environments)
Glycerol is a byproduct of saponification (Phase 2). Do not attempt to dry it. All useful forms are aqueous or paste.
| Use | Form | Notes |
|---|---|---|
| Engine coolant | 60/40 glycerol/water | Protects to -40C. Replaces ethylene glycol. |
| Leather softener | Crude, applied wet | Absorbs into collagen. |
| Gelatin plasticizer | Mixed into hot gelatin | 20-30% by weight. |
| Soap additive | Mixed during saponification | Gentler on skin. |
| Medical | Crude | Wound care, oral hygiene, laxative. |
| Explosives precursor | Crude | Glycerol + HNO3 -> nitroglycerin. For quarrying if needed. |
| Botanical extraction | Solvent | Tinctures without alcohol. |
Depends on: Phase 2 (engine running), Phase 3 (materials for fabrication).
A running IMT diesel engine is not just a tractor. With a flat belt or PTO coupling, it drives every mechanical process in this system:
black)
than gravity settling)
cylinders
A single functioning diesel engine is an entire industrial base.
Draw plate fabrication: Take a hardened steel file. Anneal (heat to red, cool slowly). Drill tapered holes in graduated sizes. Re-harden (heat to cherry red, quench in water or oil). Temper (reheat to straw/blue color, ~200-300C, air cool).
Drawing wire from scrap:
against feet, straighten legs)
wire snaps)
For tire reinforcement: target 1-2mm gauge. Production rate ~10-20 meters per hour per person at this gauge.
Wire sources for recycling:
high-tensile steel wire)
Copper wire: Reserve exclusively for future electrical applications. Do not draw copper for mechanical uses. Steel only for structural wire.
The hardest problem in the system. Three time horizons:
Cut tread sections from scrap automotive tires. Bolt as segments onto steel or wooden wheel rims. Ugly, functional. Buys time.
Weld or bolt steel plates as cleats onto steel rims. The original configuration for many tractors of this era. Works on soil. Poor on roads. Acceptable for field work.
Cultivation: Taraxacum kok-saghyz (Russian/Kazakh dandelion). Thrives in temperate climates. Loose, well-drained soil, pH 5.5-8.5, full sun. Potential yield: 150-750 kg rubber per hectare (improved cultivars). Wild/unimproved: 30-60 kg/ha. Harvest roots in autumn before hard frost.
Latex extraction: Macerate roots. Wash. Coagulate latex with dilute H2SO4.
Vulcanization: Mix raw latex with 3-5% elemental sulfur (from your sulfur supply chain). Heat to 140-160C. Cross-links the polymer chains. Add finely ground charcoal (ball-milled or wet-ground on stone) as reinforcement filler — crude substitute for carbon black.
Tire construction:
pattern
sidewalls mainly need flexibility)
Molding: Build a split mold (two halves, carved hardwood or cast iron). Pack rubber/wire layup into mold. Close. Heat to 140-160C for vulcanization.
Co-product: TKS roots are rich in inulin. After latex extraction, the remaining pulp can be fermented to alcohol (supplementary fuel).
Depends on: Phase 3 (glass vessels for distillation), Phase 4 (mechanical processing capability).
Not essential for the core fuel-and-maintenance loop. Pursue when the base system is stable and labor is available.
Boil 60-70% chamber acid in glass retorts. Water evaporates at 100C, acid remains. Continue to >90% concentration. Required for: sulfonation of fatty acids, some advanced chemical syntheses.
Fatty acids + concentrated H2SO4 -> sulfonated fatty acids (anionic surfactants). Work in hard water (unlike soap, which forms calcium soap scum).
Alternative for hard-water washing without this chemistry: saponin from soapwort (Saponaria officinalis, grows wild across Europe) or horse chestnuts (Aesculus hippocastanum). Crush roots or nuts, soak in water. Natural surfactant, no chemical processing.
Sulfonated fatty acid detergent + geopolymer or cement slurry + air (foamed). Lightweight insulating structural panels. Extension of the geopolymer system.
Copper wire (from stockpile) + permanent magnets (scavenged from motors, speakers) + lathe-turned components = generator. A rebuilt alternator on the IMT engine produces 12V DC. This enables:
