Nature as Technology

• Appeal, a materials science company, leverages 3.8 billion years of biological innovation to develop sustainable technologies that work with natural systems rather than against them.
• The company's approach focuses on identifying how nature answers environmental challenges and applying those solutions to polluting industrial sectors.

Key Biological Inspirations and Industrial Applications

• Agricultural Soil Fertility: The Amazon Basin's biodiversity is driven by nutrient transfer from the Sahara Desert, a process moving more land mass annually than all global agricultural fertilizer combined.
• Structural Coloration: Butterflies achieve color by patterning exoskeleton material to reflect specific light wavelengths without pigments, offering a path to dye-free textile manufacturing.
• Marine Drag Reduction: Shark skin utilizes a hierarchical structure across three orders of magnitude to minimize drag and self-clean, presenting a solution for energy-efficient marine transport.
• Molecular Recycling: Plants use proton gradients and molecular rotors to physically link and reuse "spent fuel" within cells, a mechanism demonstrating zero-waste energy cycles unlike current human linear consumption.
• Seed Co-evolution: Fruit evolved to be consumed by animals for seed dispersal, but modern fruit varieties often lack the durability required for contemporary food supply chains.
• Plant Desiccation Barriers: The evolution of "cutin," a thin polymeric barrier, allowed plants to survive on land by preventing rapid moisture loss and oxidation.

Company-Specific Innovations and Impact

• Technology Mechanism: Appeal synthesizes molecules from inedible plant parts to create a protective cutin-like barrier applied to edible fruit surfaces, reducing moisture diffusion and oxygen exposure.
• Shelf Life Extension: The technology extends the shelf life of perishable produce from days to weeks; specifically, the "caviar lime" (natively Australian) can transition from a 7-day lifespan to 25 days.
• Product Naming: The company name "Appeal" reflects the goal of creating fruit with "appeal," characterized by significantly extended shelf life comparable to citrus.
• Economic Potential: Solving fruit perishability could eliminate trillions of dollars in annual food losses and unlock new markets for smallholder farmers in remote regions (e.g., Kenya) and emerging production hubs (e.g., Peru to Asia).

Future Outlook and Strategic Vision

• Demographic Pressure: Adding 25 million people annually to the population will require a 70% increase in food supply and 55% more fresh water within the next 30 years.
• Historical Context: Human progress is defined by available tools, moving from the Stone, Bronze, and Iron ages to the Silicon Age.
• Emerging Era: Appeal posits that humanity is entering a new age defined by the mastery of biomimetic materials and the integration of human systems into natural cycles.
• Strategic Choice: The organization advocates for defining this new era by choosing to be part of the natural system through small, integrated material changes rather than seeking external solutions like finding a "second Earth."
