Wool is 100% Biodegradable
HOW DOES WOOL BIODEGRADE?
All materials of animal and vegetable origin have some degree of biodegradability, meaning that they are capable of being decomposed by the action of living organisms, such as fungi and bacteria. Wool is composed of the natural protein keratin, which is similar to the protein that makes up human hair. When keratin is broken down naturally by microorganisms, the products do not pose any environmental hazard.
WOOL READILY BIODEGRADES IN MOIST, WARM CONDITIONS
On disposal, if wool is kept warm and moist or buried in soil, fungal and bacterial growths develop which produce enzymes that digest wool. On the other hand, thanks to the unique chemical structure of keratin and wool’s tough, water-repellent outer membrane, clean and dry wool fibres do not readily degrade. This allows wool products to be resilient and long-lasting in normal conditions.
WOOL BIODEGRADES QUICKLY
Wool biodegrades readily in as little as three to four months but the rate varies with soil, climate and wool characteristics. This releases essential elements such as nitrogen, sulphur and magnesium back to the soil, able to be taken up by growing plants. Some studies found more rapid degradation after only four weeks’ burial in soils. Research has shown that processing treatments such as dyeing and anti-shrink treatment can affect the rate of biodegradation in soil, causing an increase in the initial resistance of wool fabric to degradation. However, this is a short-term effect, typically not persisting beyond eight weeks.
WOOL RETURNS ESSENTIAL NUTRIENTS TO THE SOIL
On burial in soil, wool becomes a slow-release fertiliser providing nutrients for uptake and growth by other organisms. Some have even used wool fertiliser to foster herb and vegetable growth. This is known as natural closed loop recycling; restoring the initial inputs of soil and grass. Other beneficial effects of adding wool to soils include enhanced water holding capacity, improved water infiltration, soil aeration and reduced erosion. Ground-up wool carpet, when used as a fertiliser, increased the dry matter yield of grass growth by 24% to 82%.
WOOL DOES NOT ADD TO LANDFILL VOLUMES OR MICROFIBRE POLLUTION
Natural fibres biodegrade naturally in a relatively short period in soils and aquatic systems and therefore do not accumulate in landfill and oceans. Results from a University of Canterbury study demonstrate that wool degrades in a marine environment. In contrast, synthetic textiles persist for many decades and can disintegrate to small fragments. Commonly known as microplastics, or microfibres when less than 5mm in diameter, these fragments accumulate in aquatic environments and land disposal sites where they have negative effects on ecosystems when consumed by organisms. A single polyester fleece garment can produce more than 1900 fibres per wash. Ingestion has a negative impact on organisms, sometimes causing death through starvation as plastic replaces food in the stomach. Once in the food chain, microplastics potentially also affect human health via seafood consumption.
At Curtain Clean we are all about minimising waste and reducing the amount of uncompostable materials going into landfill. Keep in mind that a lot of fabrics can be washed and don't need to be thrown away! Call us on 07 579 0501 if you have something you'd like cleaned, we can treat almost all fabrics.
National average asking price virtually unchanged for over a year
Since January 2023, the national average asking price has remained stable. At $868,877, it is down a marginal 0.6% on April last year. The national average asking price has remained below $900,000 since December 2022, a significant decrease from the market peak in January 2022 when it exceeded $1 million.
“As we move into the winter months, we typically see a cooling market, and in 2024, this is combined with a softening economy. It will be interesting to see how these factors play out for the property market in the coming months,” says Sarah Wood, CEO of realestate.co.nz

ANZAC DAY
Half a world away from dawn services in Australia & New Zealand, a small group of dignitaries will meet in Malta this Anzac Day among the neat rows of headstones at sun-baked Pieta Military Cemetery just outside Valletta – as they have since 1916 – to commemorate a moving but largely forgotten chapter of Gallipoli lore.
It is the story of how a tiny, ancient, impoverished and battle-scarred nation in the centre of the Mediterranean opened its arms and hearts to care for thousands of wounded, traumatised and sick young Anzacs, many of them still teenagers, who arrived aboard a flotilla of blood-soaked hospital ships from the battlefields of Gallipoli.
While most of the 57,950 soldiers evacuated to Malta recovered and eventually left, some 202 Australians and 72 New Zealanders did not, and are in war cemeteries across the archipelago.
Apart from their graves hewn from the parched, rocky Maltese earth, there is little other physical evidence the Anzacs were ever in Malta, despite the enormity of their presence over a century ago.
The voyage across the Eastern Mediterranean in these makeshift hospital ships from the Gallipoli Peninsula to Malta was not an easy one. It took the steam ships up to eight days to cover the 1163-kilometre journey.
At the beginning of April 1915, there were 824 military hospital beds in Malta. At the end of May 1915, there were more than 6000 in 14 hospitals spread all over the island. At its peak there were 25,522 beds in 28 hospitals, with the highest number of patients on any one day a staggering 16,004.
We will remember them 🥀 🌺
