Regenerative Living Glossary

A decomposition process that occurs without oxygen. In composting, this can mean sour, smelly rot — but when managed deliberately (as in bokashi), anaerobic fermentation preserves nutrients, breaks down tough fibres, and produces organic acids that suppress pathogens. The difference between failure and success is a sealed environment and the right microbial inoculant.

A carbon-rich material produced by heating organic biomass (wood, crop residues) in a low-oxygen environment — a process called pyrolysis. Biochar's highly porous structure gives soil a permanent physical framework for water retention, microbial habitat, and nutrient exchange. It locks carbon into a stable form that persists in soil for centuries.

Capable of being broken down by living organisms — bacteria, fungi, and other microbes — into water, carbon dioxide, and biomass within a reasonable timeframe. A biodegradable material returns to the earth without leaving persistent pollution. The distinction from "compostable" matters: compostable materials break down in a managed composting environment; biodegradable materials break down eventually in any environment, though the timeframe varies.

Innovation inspired by nature's time-tested patterns and strategies. Rather than inventing from scratch, biomimicry asks: how has nature already solved this problem? Termite mounds teach passive cooling. Spider silk teaches high-strength fibre. Mycelium teaches packaging that grows and decomposes. It is not copying nature — it is learning from 3.8 billion years of R&D.

An anaerobic fermentation process that breaks down kitchen waste — including cooked food, dairy, and meat — in a sealed bucket using beneficial microbes inoculated into bokashi bran. Unlike traditional composting, bokashi works indoors, finishes in weeks rather than months, and produces nutrient-rich pre-compost that feeds soil biology.

A solution of salt dissolved in water, used in lacto-fermentation to create an anaerobic environment that favours Lactobacillus bacteria while suppressing spoilage organisms. Typical concentrations range from 2–5% salt by weight of water. The brine also draws nutrients from the vegetables, feeding the fermenting bacteria and creating the tangy flavour of sauerkraut and pickles.

The process of capturing and storing atmospheric carbon dioxide in long-term sinks — soil, biomass, geological formations, or biochar. Plants sequester carbon through photosynthesis; soil sequesters it through organic matter accumulation; biochar locks it away for centuries. Every regenerative practice — composting, no-till, cover cropping — increases the soil's capacity to hold carbon.

The balance between carbon-rich "browns" (dry leaves, cardboard, wood chips) and nitrogen-rich "greens" (food scraps, fresh grass, coffee grounds) in a compost system. The ideal ratio is roughly 25–30 parts carbon to 1 part nitrogen by weight. Too much carbon and decomposition stalls; too much nitrogen and the pile goes slimy and smelly. Getting this ratio right is the single most important skill in composting.

An economic system designed to eliminate waste by keeping materials in use for as long as possible. Products are designed for durability, repair, reuse, and eventual biological or technical recycling — never for the landfill. In a circular economy, every output becomes an input for another process, mirroring how ecosystems work: no waste, only resources in transition.

A system in which all outputs are recaptured as inputs, eliminating waste and external dependencies. A kitchen closed loop might look like this: food scraps go to bokashi composting, compost feeds the garden, garden produce feeds the kitchen. No leaves. In product design, closed-loop means the manufacturer takes back the product at end of life and reuses every material.

The practice of growing certain plants together for mutual benefit — pest deterrence, pollinator attraction, nutrient sharing, or shade provision. Classic examples include the "Three Sisters" (corn, beans, squash) and basil planted alongside tomatoes to repel aphids. Companion planting reduces the need for external inputs by letting plant relationships do the work.

A liquid extract made by steeping finished compost in water, often aerated to multiply beneficial microorganisms. Used as a soil drench or foliar spray, compost tea inoculates plants and soil with diverse microbial life — the invisible workforce that makes nutrients available to roots. It is not a fertiliser; it is a biology delivery system.

The controlled biological decomposition of organic materials by bacteria, fungi, and invertebrates into a stable, humus-like product. Good composting balances carbon and nitrogen, moisture and air, to keep decomposition aerobic and odour-free. The end result — finished compost — feeds soil life, improves soil structure, and closes the nutrient loop between kitchen and garden.

Planting a crop specifically to protect and enrich bare soil between productive growing seasons. Leguminous cover crops (clover, vetch, field peas) fix atmospheric nitrogen into the soil; grasses and brassicas add organic matter and suppress weeds. When terminated, cover crops are either mulched into the surface or crimped and left as a mulch layer — feeding soil life without tilling.

A blended culture of lactic acid bacteria, yeasts, and photosynthetic bacteria originally developed by Dr. Teruo Higa. EM is used in bokashi bran, compost加速ation, and soil inoculation to speed decomposition and suppress pathogenic organisms. The concept is straightforward: introduce beneficial microbes in numbers large enough to outcompete the harmful ones.

A metabolic process in which microorganisms — bacteria, yeasts, or moulds — convert sugars and starches into acids, gases, or alcohol. It is the oldest food preservation technique known to humanity and the foundation behind sourdough, kombucha, kefir, sauerkraut, kimchi, miso, and countless other foods. Fermentation preserves nutrients, creates complex flavours, and produces bioactive compounds.

A tangy, probiotic-rich drink made by culturing milk (or sugar water for water kefir) with kefir grains — small, cauliflower-like colonies of bacteria and yeast bound in a polysaccharide matrix. Milk kefir ferments in about 24 hours at room temperature. The grains are living and self-perpetuating: they grow over time, producing more grains with each batch.

A mildly acidic, slightly effervescent drink made by fermenting sweet tea with a SCOBY — a symbiotic culture of bacteria and yeast. The SCOBY converts sugar into organic acids, carbon dioxide, and trace alcohol over 7–14 days. Once you have a SCOBY, it reproduces continuously — one culture can sustain endless batches with nothing more than tea and sugar.

A preservation method in which Lactobacillus bacteria convert sugars into lactic acid in a salt-brine environment, creating conditions too acidic for spoilage organisms. This is the process behind sauerkraut, kimchi, and pickles. The salt draws water from vegetables by osmosis, creating the brine; the bacteria do the rest. No vinegar, no heat — just salt, vegetables, and time.

Young seedlings harvested at the first true-leaf stage, typically 7–14 days after germination. Despite their small size, microgreens can contain up to 40 times more concentrated nutrients than their mature counterparts. They grow on a windowsill in a shallow tray with soil or coconut coir, requiring nothing more than light and water. Fast, productive, and fresh to your plate within minutes of cutting.

The vegetative body of a fungus — a vast, branching network of microscopic filaments (hyphae) that grows through soil, wood, or other organic substrates. A single gram of healthy soil can contain metres of mycelium. It is the internet of the forest: transporting nutrients between trees, decomposing dead matter, and forming symbiotic partnerships with plant roots that make entire ecosystems possible.

Composite materials made by growing mycelium through agricultural waste (hemp hurds, corn stalks, sawdust) in a mould, then heat-treating to stop growth. The result is a lightweight, fire-resistant, biodegradable material that can replace polystyrene foam, leather, and building insulation. It grows in days, not years, and decomposes naturally at end of life.

A soil management method that avoids mechanical disturbance — no ploughing, no rototilling. Instead, organic matter is added to the soil surface as mulch or cover crops, and soil organisms do the mixing. No-till preserves fungal networks, protects soil structure, retains moisture, and keeps carbon underground where it belongs.

A design system for creating sustainable human settlements and food-producing landscapes by mimicking natural ecosystems. Permaculture observes how forests, wetlands, and grasslands organise themselves — water flow, nutrient cycling, species diversity — and applies those patterns to gardens, farms, and communities. The core ethics are earth care, people care, and fair share.

Farming and land management practices that rebuild soil organic matter, restore degraded soil biodiversity, and sequester atmospheric carbon. Core methods include no-till, cover cropping, diverse rotations, managed grazing, and compost application. The goal is not just to sustain yields but to improve the land's productive capacity over time.

A way of life that actively restores and rebuilds natural systems rather than merely reducing harm. Where "sustainable" aims to maintain the status quo, regenerative living aims to leave things better — soil richer, ecosystems more diverse, communities stronger. It shows up in what you compost, what you buy, how you grow food, and which businesses you support.

Symbiotic Culture of Bacteria and Yeast — a rubbery, disc-shaped biofilm that sits on top of fermenting sweet tea to produce kombucha. The yeast converts sugar to alcohol; the bacteria convert the alcohol to acetic acid. Together they create a stable, self-reproducing culture. Each batch of kombucha typically grows a new SCOBY layer, so one culture becomes many.

Harvesting and storing seeds from open-pollinated plants to grow again in future seasons. Unlike hybrid seeds, open-pollinated varieties produce offspring true to type, letting you develop locally adapted strains over time. Seed saving preserves genetic diversity, reduces dependence on commercial seed suppliers, and deepens your connection to the plants you grow.

The continued capacity of soil to function as a living ecosystem that sustains plants, animals, and humans. Healthy soil is not just dirt — it is a teeming community of bacteria, fungi, protozoa, nematodes, and earthworms working in concert. A single teaspoon of healthy soil contains more microorganisms than there are people on Earth. Soil health underpins food security, water filtration, and climate stability.

Bread leavened with a naturally fermented culture of wild yeast and lactic acid bacteria, maintained as a living "starter" fed with flour and water. Sourdough fermentation breaks down gluten and phytic acid, improves mineral absorption, and creates the complex tang and open crumb structure that commercial yeast cannot replicate. A well-maintained starter can live for years — or decades.

Composting with earthworms — typically Eisenia fetida (red wigglers) — that consume organic waste and cast nutrient-rich vermicompost. A well-managed worm bin processes food scraps into dark, crumbly compost loaded with microbial life and plant-available nutrients. It works indoors or outdoors and fits neatly under a kitchen sink.

A philosophy and design principle aimed at sending nothing to landfill, incineration, or the ocean. Zero waste prioritises refusing what you don't need, reducing what you consume, reusing what you have, repairing what's broken, and composting what remains. It is a direction, not a destination — every step toward zero waste reduces your environmental footprint.
