2. Introduction of the project

2.1 Identification of Project Proponent:

The objective of this pre-feasibility study is to provide information for the Pesticides and

Chemical Intermediates manufacturing unit of Astec Lifesciences Ltd. at Plot No. B-16, 17,

18 and B-21, MIDC Mahad, District Raigad, Maharashtra.

As per the EIA Notification No S. O. 1533 promulgated on 14th September 2006, proposed

expansion project has covered Pesticides Industry and pesticide specific intermediates as 5 (b) and

need prior environmental clearance. It is stated that 5(b) industries located in a notified

industrial area are classified in category A and would be appraised by Centre Level Expert appraisal

committee. Based on the OM dated 16th May 2014 by Director MoEF, Public Hearing is

exempted for the Industrial Estates / Parks which have taken Environmental Clearance.

Introduction of the Project Proponent

Mr. Ashok Hiremath, Managing Director, Astec LifeSciences, is a Masters of Arts from

University of Oxford and Post Graduate Diploma holder in Chemical Engineering from University

College, University of London. He started his career as Project Engineer in 1978 with GEA Air

exchangers Ltd., London. He returned to India in 1980 and joined Hiremath Chemicals Ltd., a

company promoted by his brother as Technical Manager where he was responsible for

manufacturing and business development. After leaving this company in 1994 from the post of

Technical Manager, he established Astec Lifesciences Ltd. as one of the promoters and since

then he has been actively involved and played a key role in the growth of the Company with his

inputs in strategic planning and business development.

2.2 Nature of project:

The expansion project will be done at Plot No B-16, 17, 18 and B-21 at MIDC Industrial area

Mahad with land admeasuring 13950 Sq Meters. The land is already in demarcated as “Industrial”

in a notified industrial area and is not a prime agricultural land. Thus there is no change in the land

use status.

2.3 Need for the project and its importance to the country and or region:

India's Chemical industry is the third largest in the world in terms of volume. Its rank is 14 in terms

of value. India is also one of the top five active Chemical ingredients producers (with a share of

about 6.5%). The ever-increasing demand for Pesticides and Intermediated in India and abroad as

well as changing market conditions requisite Indian Chemical industries to grow further.

August 2017

Sadekar Enviro Engineers Pvt. Ltd. Page 7

The company aims to expand its product portfolio further in order to cater to Domestic &

International markets by expanding its production capacities. These products will serve to cut the

supply of imports from foreign countries thus saving currency and at the same time will earn

valuable foreign currency by export of the proposed products.

Astec Lifesciences Limited is a global supplier of Pesticides and chemical intermediate to the other

chemical companies worldwide. Astec Lifesciences Limited aims to expand its product portfolio

further in order to cater to domestic & international markets by expanding its production capacities.

These products will serve to cut the supply of imports from foreign countries thus saving currency

and at the same time will earn valuable foreign currency by export of the proposed products.

2.4 Demand supply gap

Competition in the Indian Chemical market swelled in recent years, with increasing generic

penetration. This had many companies opting out of low-margin segments, as competition resulted

in lower prices. This created a gap between demand and supply. Such unusual price hikes take

place when there is withdrawal of some of the key competitors, which leads to demand override

and as a consequence prices start soaring in a free-pricing market.

2.5 Import Vs. Indigenous production

The proposed products including production of pesticides and chemical intermediate have huge

demand in the domestic as well as export market. Production of these pesticides and chemical

intermediate are domestically reduces the need to import products along with significant scope for

export in these products.

2.6 Export & economic feasibility

The Indian crop protection industry is of USD 4.25 billion in FY14 and is expected to grow at a

CAGR of 12% to reach USD 7.5 billion by FY19. Exports currently constitute almost 50% of

Indian crop protection industry and are expected to grow at a CAGR of 16% to reach USD 4.2

billion by FY19, resulting in 60% share in Indian crop protection industry. Domestic market on the

other hand would grow at 8% CAGR, as it is predominantly monsoon dependent, to reach USD 3.3

billion by FY19. Globally, India is fourth largest producer of crop protection chemicals, after

United States, Japan and China. The crop protection companies in India can be categorized into

three types –Multi-National, Indian including public sector companies and small sector units.
