Airbrige Greens

‘Airbridge Greens’ a new feather of success in the crown of ‘Airbridge Group’ is a milestone to expand rural employment and activities. One of its major objectives is to produce Biodiesel. Airbrige Greens are the pioneer in the Northern, North-Eastern and Eastern region in Biodiesel production. We have installed a Biodiesel plant at Howrah, West Bengal, India. We have a working Biodiesel plant with production capacity of 30,000 L/Day and soon we are planning to extend capacity with 100,000 L/day under the brand name of “green Diesel” – Biofuel. As per Biodiesel policy of Govt. of India, we will supply Biodiesel as per the standards specified by “Bureau of Indian Standards” for Biodiesel – IS: 15607-2005.

Jatropha Curcas

History: Jatropha curcas originated in Central America and was introduced in India by the Portuguese. It adapted well to Indian conditions, including semiarid marginal sites. It can withstand drought by shedding most of its leaves to reduce transpiration loss. The fallen leaves add to the organic matter in the soil and improve its fertility. It is a soft wooded shrub or small tree with whitish watery latex. Animals do not browse it. Seed yield varies from 2-3 Kg/ plant to 4-6 Kg/plant. The oil content in seed varies from 25 to 48%. On an average 3.28 kg of seed gives one liter of oil. It has a low gestation period (2 years) for seed production compared to other non-edible oil bearing plants. Some varieties start yielding from first year onwards but the maximum production is reached in 3-5 years. The productive age of Jatropha is about 40 years. Significance: As soon as the Biodiesel technology gained attention worldwide, many people began planting soy bean, palm, rapeseed etc to produce Biodiesel. But soon issues were raised on food supply shortage which has contributed to increase the prices of the crops. When we know that the food supply for the world is insufficient then how can we use palm oil, rape seed and soybean to produce Biodiesel? Hence, the world has now turned to a species of tree called Jatropha simply because it is non-edible plus it has high percentage of free fatty acids. Plants of this species are promising source of Biodiesel or in other words we can say that it is biofuel crop producing seeds with high oil content. Besides we need a perennial crop to reduce the re-plantation costs and that not only it can be used for producing Biodiesel but also it benefits in restoring the previously degraded and unfertile land. Jatropha plant species is a promising source of Biodiesel or in other words we can say that it is a biofuel crop producing seeds with high oil content. Additionally, it can grow well for about 40 years and can even thrive on infertile soil. Propagation: Jatropha curcas is being propagated by seeds, cuttings and also by plant tissue culture technique. Intercropping: So far castor is the best crop for intercropping with Jatropha. We have intercropped castor plant in between Jatropha plants which are planted in a 2m×2m dimension. Until that time Jatropha plants achieve their full maturity, i.e. in 2-3 years castor plants can be well grown around the former. As the crop can be cultivated in drought prone areas and needs a hot and humid climate, thus it can be grown as a cash crop on such lands. Castor seeds contain about 48-52% of oil rich in triglycerides (mainly ricinolein). It also contains a poison called ricin which makes it inedible. The oil is usually used for medicinal purposes, as lubricant, as a raw material for colors but in future it would be required as a raw material for manufacture of Biodiesel. This makes it yet another product for export to industrialized countries. Send Enquiry

Oil Seeds and Cakes

We are using high quality oil seeds both for growing plants and also for extraction of oils such as Jatropha oil to produce Biodiesel. After extracting oil from the seeds the remaining matter that is left behind as byproduct is oil cake. These oil cakes such as Jatropha oil, Pongamia oil and castor oil cakes are rich in nutrients and can be used for a wide variety of applications. Jatropha oil cakes contains all the micro and macro nutrients like Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, Zinc, Iron, Copper, Manganese, Boron and Sulfur thus has high nutritive value. In this way, the cake is an excellent medium to reduce the dependence on chemical fertilizers and can be used as organic manure. The cake can also be used for biogas before composting and both these processes will improve the domestic energy status and nutrient availability as fertilizer to the crops. It has both insecticidal and molluscicidal properties. Castor oil cakes have many uses like its use as an organic fertilizer when supplemented with ammonium sulfate can be used for rice, banana, tomato, potato, tobacco, wheat/barley, maize, jute, sugarcane crops and when it is mixed with urea in equal amounts can be used as a nematicide. Pongamia seeds have about 30-35% oil and up to 27-28% oil can be expelled by crusher and most of the physical and chemical properties of the oil is almost similar to those of the diesel. Oil is also used as a lubricant, water paint binder, pesticide and in soap making and tanning industries. It is also a drought resistant plant. Oil cakes are good organic fertilizer and bears nitrogen 4%, phosphorous 1% and potassium 1%, which is better than vermicompost. Root nodules formation due to Rhizobium strains in nursery and in fields is common by which nitrogen is replenished in soil. Dense network of lateral roots of Pongamia control soil erosion. Leaves also act as good manure. Send Enquiry

Bio Glycerin

Bio glycerin is the major byproduct obtained after Biodiesel production. Bio glycerin is in its crude (impure) form which has a variety of uses starting from manufacturing soaps and various cosmetic products. Send Enquiry

Bio fertilizers

Organic fertilizers or Bio fertilizers can be identified as plant extracts and Bio manures. These Bio fertilizers can be further defined as urban wastes compost, various microbial mixtures with unidentified constituents, manures and chemical fertilizer formulations supplemented with organic compounds to improve the soil fertility. We offer a wide range of organic fertilizers namely, vermicompost, organic manure etc. Send Enquiry

Phytonutrients

There 16 elements that are considered necessary for plant growth. The basic elements namely carbon, hydrogen and oxygen are obtained from air and water. There are six ‘macro’ nutrients namely Nitrogen(N), Phosphorus(P), Potassium(K), Calcium(Ca), Magnesium(Mg) and Sulfur(S) which are absorbed in large amounts and then there are seven ‘micro’ nutrients namely iron(Fe), Manganese(Mn), Boron(B), Zinc(Zn), Copper(Cu), Molybdenum(Mo) and Chlorine(Cl) are absorbed in small amounts from the soil or a hydroponics solution. The ratio of the nutrients available is always important as an excess of one nutrient may result in a deficiency of another element. So under intensive production systems, the growth nutrients or elements of which the soil has the smallest reserve in relation to the plant requirement are the first require replenishment.

Plant Tissue Culture

Plant Tissue Culture is a relatively recent technique adopted in commercial horticulture. The first significant use of in vitro techniques in horticulture took place during the 1920s when orchid seeds were successfully germinated. Later, the potential for using tissue culture for production of virus free Cymbidium was recognized by Morel in 1960. Soon these methods were adopted for commercial propagation of large number of plats. Now, tissue culture is an accepted practice for commercial plant multiplication in horticultural industry throughout the world. Plant Tissue Culture techniques provide a much degree of control over plant development through conventional methods. In the tissue culture practice, explanted tissue, organs and cells are aseptically grown on a synthetic growth medium under specific incubation conditions of light, temperature and humidity. Each step starting from aseptic establishment of culture to transfer of plants to the general growing conditions in the field is vital. We are going to establish plant tissue culture laboratory practices for Jatropha curcas, Castor and many varieties of medicinal and ornamental plants very soon. In addition to that, we will also provide infrastructure for plant tissue culture laboratory. Send Enquiry
