Our product, The Converter, is an innovative way to manage waste, transforming all forms of rubbish into a safe, dry, and reduced final product using a completely mechanical process that harnesses the principle of mechanical to thermal energy transformation.

The key benefits of OMPECO are:
- Zero Emissions: No pollutants or harmful substances released.
- Safe Output Material: Produces sterile, odourless, dust-free, non-fermenting, and vermin-free material.
- Significant Reduction: Up to 50% weight reduction and up to 80% volume reduction- Zero Landfill.
- Environmentally Friendly: No use of chemicals, combustion, microwaves, or pressure.

The Converter is a 100% sustainable, zero waste, zero emission solution that eliminates the need for waste separation. Simply load the machine, The Converter will remove any liquid, converting the waste into premium grade refused derived fuel (RDF) with high calorific value in only 30 minutes. The resulting RDF is a sterile, inert flock suitable for fuel or domestic disposal, eliminating odors, dust, and refrigeration needs while ensuring long-term storage stability. This can then be safely stored or even sold on for use in the circular economy (see attachment on medical waste)

Mace
Botanical: Myristica fragrans
Family: N.O. Myristicaceae
Hindi Name: Mace - Javitri
General Description: Nutmeg, spice consisting of the seed of the Myristica fragrans, a tropical, dioecious evergreen tree native to the Moluccas or Spice Islands of Indonesia.
Geographical Sources
The nutmeg tree, Myristica fragrans, is indigenous to the Moluccas in Indonesia but has been successfully grown in other Asian countries and in the Caribbean, namely Grenada. Banda Islands, Malayan Archipelago, Molucca Islands, and cultivated in Sumatra, French Guiana
Composition -> Nutmeg and mace contain 7 to 14 percent essential oil, the principal components of which are pinene, camphene, and dipentene. Nutmeg on expression yields about 24 to 30 percent fixed oil called nutmeg butter, or oil of mace. Dried kernel of the seed.

Varieties -> Whole nutmegs are grouped under three broad quality classifications:
1. Sound: nutmegs which are mainly used for grinding and to a lesser extent for oleoresin extraction. High quality or sound whole nutmegs are traded in grades which refer to their size in numbers of nutmegs per pound: 80s, 110s and 130s (110 to 287 nuts per kg), or 'ABCD' which is an assortment of various sizes.
2. Substandard: nutmegs which are used for grinding, oleoresin extraction and essential oil distillation. Substandard nutmegs are traded as 'sound, shrivelled' which in general have a higher volatile oil content than mature sound nutmegs and are used for grinding, oleoresin extraction and oil distillation; and 'BWP' (broken, wormy and punky) which are mainly used for grinding as volatile oil content generally does not exceed 8%.
3. Distilling: poor quality nutmegs used for essential oil distillation.Distilling grades of nutmegs are of poorer quality: 'BIA' or 'ETEZ' with a volatile oil content of 8% to 10%; and 'BSL' or 'AZWI' which has less shell material and a volatile oil content of 12% to 13%.
Method of Processing -> When fully mature it splits in two, exposing a crimson-coloured aril, the mace, surrounding a single shiny, brown seed, the nutmeg. The pulp of the fruit may be eaten locally. After collection, the aril-enveloped nutmegs are conveyed to curing areas where the mace is removed, flattened out, and dried. The nutmegs are dried gradually in the sun and turned twice daily over a period of six to eight weeks. During this time the nutmeg shrinks away from its hard seed coat until the kernels rattle in their shells when shaken. The shell is then broken with a wooden truncheon and the nutmegs are picked out. Dried nutmegs are grayish-brown ovals with furrowed surfaces. Large ones may be about 1.2 inches long and 0.8 inch in diameter.
Taste and Aroma: Nutmeg has a characteristic, pleasant fragrance and slightly warm taste

Specification Quality standard: USP36
Appearance Off-white powder
Assay 95.0-105.0%
Melting range 81.0~86.0
Impurities
Any individual impurity: 3.0%
The sum of all of the impurities: 4.5%
Loss on drying 0.5%

Packaging and storage: 1kg/aluminum foil bag. 25kg/barrel, pharmaceutical packaging barrel. Sealed, stored in dark, with a shelf life of 2 years.

Reference dosage:
The hygiene standards for cosmetics stipulate that the maximum amount added shall not exceed 5%, and the general dosage is 1-4%.

Usage:
Sunscreen agent-1789 is the most effective fat soluble UVA filter and is a safe and effective UVA sunscreen approved by the US FDA for sale on the counter. It can effectively block UVA, thereby increasing the SPF value of sunscreen products. It can improve the efficacy of sunscreen products when used in combination with UVB filters, and BL-200 has the best effect when used in combination with octyl methoxycinnamate. BL-200 can increase its stability in the product. It has an extremely effective protective and repairing effect on human skin.

Application:
This product is soluble in oil and can be formulated into a cream using the usual method. However, the product turns red when it encounters metal ions, so other components such as formula water should not introduce metal ions. The equipment should be made of pure stainless steel, and an appropriate amount of EDTA-2Na should be added to the formula water phase to chelate with metal ions.

Natural Gypsum:

Gypsum (CaSO4.2H2O) is a naturally occurring mineral mined from deposits formed by ancient sea beds as a raw material, white when pure, but commonly grey, yellow, red or brown, owing to impurities. The anhydrous form (CaSO4), anhydrite, is common. We are enlisted amongst the topmost INatural Gypsum Importers and Exporters from India.

Applications:

Gypsum has many industrial applications in its raw or Calcined forms, especially in the building and construction industries. Uses of Raw Gypsum are principally as:
- a retarder for Portland cement
- a fertilizer or soil conditioner
- mineral filler
- oxidizing agent in glass manufacture or other industrial applications.

Most gypsum is calcined and used in the manufacturing of plaster products. Wallboard and plaster requires gypsum contents greater than 85%, although producers prefer a minimum of 94–95% along with whiteness in color. The major consumers of the Gypsum at present are Cement Industry. By weight about 4% to 6% Gypsum in crushed condition is utilized in Portland Cement Manufacture after mixing with cement/clinker. Gypsum acts as a retarder and controls the setting time of cement.

Imported Gypsum from Iran:

Natural Gypsum is one of the most superior qualities and consistent material available for Import and Export. Natural Gypsum has adequate whiteness, high purity as well as it is low in cost which makes it absolutely feasible for white cements as well as Plaster Of Paris manufacturing and for the Cement Industry all together. One more important quality that distinguishes Natural Gypsum from others is its hardness which is less as compared to other sources and allows different industries to easily grind the same for processing into final product which in turn results in to reduced power consumption for manufacturing industries.
