Problem:

1.The urban area of Bangladesh generates approximately 16,015tons of waste per day, which adds up to over 5.84million tons annually. It is projected that this amount will grow up to 47,000tons/day and close to 17.16 million tons per year by 2025.Existing infrastructure for waste management showed that waste collection efficiency in different urban areas with an average of 55%. 2. Acetic acid is a key chemical for RMG sector, But in Bangladesh there is no manufacturing company. All are imported from Chaina or other country, that's why our RMG sector faces difficulty.

3.For Using chemical fertilizer in our soil, Organic content is decreased day by day, That's why fertilizer requirement per hectre is increasing day by day.

Solution:

We have isolated an yeast , that convert the Organic waste to acetic acid and organic fertilizer.

If we can implement our project , we will be able to utilize the hazardous waste to a economical product.

What is the problem you are solving?

The urban area of Bangladesh generates approximately 16,015tons of waste per day. It is projected that this amount will grow up to 47,000tons/day by 2025. About 78%solid waste is coming from residential sector and 20%from commercial sector, 1%from the institutional sector and rest from other sectors.Existing infrastructure for waste management showed that waste collection efficiency in different urban areas varies from 37%to77%with an average of 55%. Huge amount of uncollected waste, a high proportion of which is organic, makes nuisance and pollutes the local environment rapidly. Solid waste disposal poses a greater problem because it leads to land pollution if openly dumped, water pollution if dumped in low lands and air pollution if burnt.

Acetic acid is a key chemical for RMG sector, Yearly consumption of acetic acid in Bangladesh is 90ktons, and It is projected that this amount will grow up to 130ktons/year.But in Bangladesh there is no manufacturing company in Bangladesh. All are imported from Chaina or other country, that's why our RMG sector faces difficulty.

For Using chemical fertilizer in our soil, Organic content is decreased day by day.In 1992-93 total fertilizer consumption was 2300000tons, but today this value is upto 7100000tons.

Who are you serving?

This is a global problem. About 100 million of urban people are affected by this problem. Two case studies(Agargaon and TT Para) are given below to illustrate the problems of the poor, due to garbage in the city:

• People are Allergic to mosquito bites and most of the time the children are ill. • Flies are abundant due to the nearby garbage. • They suffer from odur and excess of stagnant water. • Their eyes become red when they go out, under the sun. • They also experience aches in their eyes.

In recent year, acetic acid price is raised rapidly that's why dyeing industry are affected. There manufacturing cost have increased.

Fertilizer requirement in our country land is increasing day by day for using chemical fertilizer that's why their production cost also increased, and Farmers are being affected.

So if we can implement our project we will be able to minimize these problem.

What is your solution?

Our product is Acetic acid & Organic fertilizer.
Process & Technology:

We have isolated an yeast that convert the food waste to acetic acid and residue (spent wash) by fermentation process. This will take 7 days long. After in liquid -liquid extraction and crystallization process it produce glacial acetic acid(GAA), In laboratory, manufacturing cost is 67taka/kg. But we hopeful in industrial level it will be 53 to 57 taka /kg GAA.

Then the residue is treated by a microbe. which increase the nitrogen content of our fertilizer by nitrogen fixation process. After 21 days it become a brown color granully.

Per 1 kg of organic waste produce 0.236 kg of acetic acid and 415gm of organic fertilizer.
