HAMPBOX

Overview

HAMPBOX is a multi-cycle logistics crate made from a polypropylene + industrial-hemp-fiber composite, engineered to replace single-use cardboard in food logistics. It targets the hidden ~10 % "packaging tax" on shelf price — waste fees, wet collapse, repacks, crushed product, and ~3 % packaging-caused shrinkage — by surviving 100+ rotations with stable form, full stackability, and minimal sanitation loss.

Applications

Reusable crates for fresh-produce field-to-shelf logistics; reverse-flow and crate-pooling networks; any supply chain currently using single-use cardboard. Fits existing pallet, rack, and conveyor systems without adaptation.

Users: produce growers/shippers, retailers, logistics and pooling operators.

Operating Principle

A substantial loading of industrial hemp fiber is bonded into a polypropylene matrix; hemp adds stiffness, tensile strength, and micro-fracture resistance, while PP provides washability, moldability, and stability. The core innovation is a proprietary fiber–polymer bonding interface, developed and tuned over an extended R&D program, giving structural rigidity with flex control, low fatigue, corner/stack impact damping, and coating-free antimicrobial resistance.

Limitations: cycle-life and savings figures are claims from pilots; long-term composite fatigue and wash-cycle durability need broader validation.

Key Parameters

Material: PP + industrial hemp fiber, at a proprietary fiber loading optimized for stiffness without sacrificing moldability. Tensile strength: +12–15 % vs standard PP. High impact/abrasion/stacking resistance. Water: zero absorption, washable, chemically stable. Hygiene: biofilm-resistant, survives aggressive wash. Ventilation geometry prevents anaerobic zones. Cycle life: 100+ reuse events. Form factor: drop-in for existing pallet/rack/conveyor systems.

Note: cycle life and durability are pilot claims requiring broader operational validation.

Architecture and Components

PP–hemp composite crate body; engineered fiber–polymer bonding interface; ventilation geometry for cold airflow; standard pallet/rack/conveyor-compatible form factor. No coatings required for antimicrobial performance.

Advantages

Technical: 100+ rotations, no water absorption, washable, biofilm-resistant, stable stacking. Economic: amortized €0.6–0.9/cycle vs €3.93/trip single-use; up to €4,100 saved per 20 t truckload; payback in 15–18 rotations. Environmental: eliminates single-use cardboard waste, reduces product loss/shrinkage, supports circular reverse-flow logistics.

Integrations

Drop-in to existing pallet/rack/conveyor and crate-pooling/reverse-flow systems; complements ARBOK composite-materials and circular-logistics platforms.

Deployment & Operation

Steps: introduce crates into field-to-shelf flow → wash and return via pooling → reuse 100+ cycles. Compatible with existing equipment; no infrastructure adaptation. Remaining: broader operational validation of cycle life and savings across networks.

TRL

TRL 5 (confirmed by Michael). Validated in a relevant environment: piloted across fresh-produce networks (EU and North Africa) with claimed cost-savings, hygiene, and survivability data, but broad multi-network validation and long-term fatigue data are still accumulating. (Adjusted from the legacy "TRL 8" claim.)

TRL scale:

• TRL 1 — basic principles observed
• TRL 2 — technology concept formulated
• TRL 3 — experimental proof-of-concept
• TRL 4 — validated in lab
• TRL 5 — validated in relevant environment ← HAMPBOX
• TRL 6 — demonstrated in relevant environment
• TRL 7 — prototype in operational environment
• TRL 8 — system complete and qualified
• TRL 9 — proven in operational environment

Market Potential

Single-use cardboard imposes a structural ~10 % cost on produce supply chains across billions of boxes. A drop-in reusable crate with sub-18-rotation payback — if pilot economics hold at scale — addresses fresh-produce logistics and pooling markets, especially where reverse-flow infrastructure already exists.

Typical Project Economics

Single-use: €2.6 + €0.2 disposal/damage + €1.1 product loss = €3.93/trip. HAMPBOX: €0.6–0.9/cycle amortized. Per 20 t truckload: up to €4,100 saved. Payback: 15–18 rotations. Figures indicative; depend on system discipline and return rates.

Risk Factors

Savings/cycle-life are pilot claims — return rates and pooling discipline drive real ROI; lost/under-cycled crates erode economics. Long-term composite fatigue and wash durability need validation. Higher upfront cost than cardboard. Requires reverse-logistics infrastructure. Legacy TRL overstated.
