  Vision for stepping into
Flexible Packaging
  During the course of organization’s vision to broaden the horizons, in year 2005 Mr. Vipul Bhalodia, founder of STP group explored some project reports related to packaging industries into flexible packaging. As envisaged the growth was planned to be into packaging products itself, he witnessed a report published by “Centre for Polymer Science & Engineering, Indian Institute of Technology, Delhi,” (of April 2002) about “Life Cycle Analysis of PP-HDPE Woven Sacks vis-Ă -vis Jute/Paper Sacks in Terms of Environmental Studies”.

The report elaborated that, though plastics like PP-HDPE were relatively newcomers by 2002 but the use of these materials in packaging commodities adhere the basic tenets of sustainable development more than materials like Jute and Paper, if one considers the consumption of energy, emission of gases and the use of chemicals.

It also covered an analysis of the comparable life cycle with jute and paper, clarifying; plastics are economically affordable, socially acceptable and environmentally effective as well, health hazards for workers in jute and paper are very high while those employed in plastics are almost free from such health hazards. It highlighted the fact that such hazard on workers and environment is caused by massive use of fertilizers, insecticides and chemicals in jute and paper. On the contrary, the use of PP-HDPE is not only safe, but as a whole actually saves more oil than needed for their manufacture.

The report presented the graphical illustration of energy, water and gases consumption, in all the three materials; Jute Sacks, Paper Sacks & PP-HDPE Sacks, and removed the prevailing notion that jute and paper are more environment friendly than PP-HDPE.

Other sensitivity in the outcome was about discovering the effects of the weight of the Jute vis-Ă -vis PP-HDPE woven sacks, on the overall loss to environment. Jute and paper as bulk packaging material causes more stress on waste management than PP-HDPE woven sacks. It revealed that PP-HDPE-based bulk packaging is a vehicle for sustainable development, and is fully renewable and recyclable and it is a wrong perception that it damages the health of environment. Instead of discouraging its production, the need of the hour is educating the policy makers to maximize its usage. After all, these polymers perform dutifully the role of a carrier effectively from the doors of producer to consumer.

This notion strengthened one amongst the prime steps towards entering into this new flexible packaging business, which proved to be the most eco-friendly production business.
  STP’s Waste Treatment Technologies & commitment for Green Mfg.
Treatment of waste at STP means recovery of waste, for which we, which renders it harmless, for final disposal. Waste treatment includes temporary storage but not collection and transportation of waste. Waste is temporarily stored when it later undergoes towards waste treatment process.

Waste treatment technology is divided into the following sub-categories:
(a) Reuse/Recycling
(i) Reuse term is applied when the additional use of product is intended; after it’s standard usage cycle. It does not include any manufacturing process, however, cleaning, repair orrefurbishing may be done for secondary usages.
(ii) Recycling is reuse of materials from scrap or otherwaste materials for the re-production. For the purpose of eco-efficiency, reporting companies contact us for recycling of the materials they have procured from us for recycling of the same.
(b) Waste incineration
  At STP we incineratethe waste; mineralizes it and reduces the volume of solidresiduals. It results in the output of "other" waste streams that are airemissions, ash, slag& heat etc., which are treatedadequately.
