After researching traditional vermicomposting methods for managing dairy farming waste, I found that using dairy cattle manure, high-nitrogen organic materials, and ruminant digestion microbes can help people respond to their consumption, create greenery or expansion, and withdraw carbon when done paper waste sorting regularly.

White Sack is in responsibility for sorting cardboard, corrugated fibreboard, mould pulp, and other paper waste. In order to encourage people to rethink their disposal of paper waste due to misunderstandings, they should be converted into vermicompost using an organic process rather than burning it. When unsorted paper waste becomes wet, it emits printing ink, bleach, and glue. As a result, paper waste cannot be managed by landfills as rapidly as people assume.

It takes a few weeks to implant Archeae in decomposing paper waste, which begins with the chemicals from sorted paper waste decomposing. Ruminant digestion microorganisms are then added. Archeae, which function as a domain for microorganisms, will facilitate the growth of microbes from ruminant digestion while modifying those materials to serve as food for earthworms when the surroundings is suitable. Vermicompost will be ready to sift for harvest in 9-11 weeks when moist dairy cattle manure and decomposing paper waste with microbes are combined 2:1. When the moisture content of the bedding (White Sack’s sorted paper waste management unit) drops, most of the earthworms will hibernate. The young hatchlings that are smaller than grid net may grow up in areas that have been fertilised with White Sack vermicompost. Because vermicompost contains microbes that will grow when watered, it will enhance the greenery where it is utilised. It also helps earthworms grow their food supply and may even be applied by wild earthworms to naturally develop greenery.

Sorting one kilogramme of corrugated fibreboard to feed White Sack’s vermicomposting might result in about 26.2 kilogrammes of carbon offset annually.

White Sack could develop into a public facility to handle sorted paper waste while preserving green spaces, planting new trees, or encouraging the development of organic farming.

Professional laboratory testing certified White Sack's vermicompost with positive results. It offers the same advantages that traditional vermicomposting products.
