Compost manufactured by Envcares has the Singapore Environment Council Green Label Certificate as an eco friendly product.

The manufacturing method is called an In-vessel aerobic thermophilic process.

This promotes care of the environment in Singapore through the conversion of organic wastes such as tree wastes into organic resources, significantly reducing the use of chemical fertilizers and avoiding the generation of chemical pollutants.

Our philosophy centers on the production and development of natural compost at low cost by seeking and utilizing only organic waste materials through our proven and optimized processes, generating a virtuous cycle of circularity and sustainability.

The decomposition of organic matters into humus like materials by the action of multiple microorganisms undergoing physical and chemical reactions. As a biological process, there needs to be right amounts of inut nutrients, water and oxygen. Compost releases nutrents over time creating their own micro habitates useful for plants

Composting is an aerobic process whereby microorganisms consume oxygen while feeding on liquid or solid organic materials. As part of the decomposing process, organic materials begins to be broken down. Decomposting requires a variety of bacteria and fungi, each playing their own part.  Carbon dioxide is also one putout. Composting is carbon neutral as the original makeup is from carbon base. Ie composting is a carbon neutral process.

Composting uses oxygen ie an aerobic process. Good aeration and water are needed for proper composting. If there is insuffienct oxygen is provided, the process can become anaerobic and may eventually lead to methane generation. Water is an essential item for microorganisms for nutrient processing and ionic exchange through cell walls.  A good carbon source (ie browns) is also need for bacteria to feed on.

Some factors impacting composting process.

  • Oxygen levels. – maily ensuring the there is sufficient air flow and exposure
  • Moisture and hence measured by moisture conten
  • Temperature. An aerobic thermophilic temperature range between 55 to 70C.
  • Carbon source. This affects the C:N ratio. A good mix of woody materials along with greens
  • pH of the input materials and final prducts
  • Size of the organic materials The higher the surface area ratio to the particle size, the better for composting

Composting takes place over three range of temperatures:

  1. Mesophilic, usually 20oC to 45oC. Here bacteria break down cellulosic materials into various sugars, proteins and starch. At room temperatures, this may give rise to unpleasant odours
  2. Thermophlilic 45oC to 70oC. As the pile temperature rises, thermophilic bacteria comes into play. The rise in temperature will also kill off much of mesophilic bacteria, weeds, spores, seeds, pathogens such as pest and their eggs/larvae. The higher temperatures also accelerates the decomposition process
  3. Curing/mesophilic  – below 45oC. Metabolic activity is reduce and the pile temperature starts to drop
  4. Maturation – 20oC to 30oC. During maturation, the compost pile temperature drops to ambient temperature and decomposition slows down.
