Chintamani

Chintamani Portfolio

Chintamani is located at Karnataka. It has an average elevation of 865 meters (2837 ft). It is a taluk headquarter and part of Chikkaballapura district. It became a part of Chikkaballapura district in 2007 when Kolar district was split. The name Chintamani is supposed to be given by a Maratha warrior who had camped in this place long ago. The economy is agriculture based. Chintamani is famous for Tomato and Mango and Banana. Srinivaspur, an adjoining town 18 kilometers away, is very famous for Mango production.

Project Detail

Waste management is the collection, transport, processing, recycling or disposal, and monitoring of waste materials. The term usually relates to materials produced by human activity, and is generally undertaken to reduce their effect on health, the environment or aesthetics. Waste management is also carried out to recover resources from it. Waste management can involve solid, liquid, gaseous or radioactive substances, with different methods and fields of expertise for each.

In HWM we Process Organic waste by Biological reprocessing such as Anaerobic digestion and Compositing and we recycle Inorganic waste by Effective recycling methods.

Organic waste

• Organic waste is a major component of municipal solid waste. Most originates from household waste but commercial, institutional and industrial waste can also contain significant proportions of organic waste e.g. market waste. Organic waste is biodegradable and can be processed in the presence of oxygen by composting or in the absence of oxygen using anaerobic digestion. Both methods produce a soil conditioner, which when prepared correctly can also be used as a valuable source of nutrients in urban agriculture. Anaerobic digestion also produces methane gas an important source of bio-energy

In HWM we have planned the below methods to Handle Organic waste • Composing • Anaerobic digestion

Composting Organic matter constitutes 35%–40% of the municipal solid waste

generated in India.This waste can be recycled by the method of composting, one of the oldest forms of disposal. It is the natural process of decomposition of organic waste that yields manure or compost, which is very rich in nutrients.

Composting is a biological process in which micro-organisms, mainly fungi and bacteria, convert degradable organic waste into humus like substance. This finished product, which looks like soil, is high in carbon and nitrogen and is an excellent medium for growing plants. The process of composting ensures the waste that is produced in the kitchens is not carelessly thrown and left to rot. It recycles the nutrients and returns them to the soil as nutrients. Apart from being clean, cheap, and safe, composting can significantly reduce the amount of disposable garbage. The organic fertilizer can be used instead of chemical fertilizers and is better specially when used for vegetables. It increases the soil’s ability to hold water and makes the soil easier to cultivate. It helped the soil retain more of the plant nutrients.

Continued… Vermi-composting • Vermi-composting has become very popular in the last few years. In this

method, worms are added to the compost. These help to break the waste and the added excreta of the worms makes the compost very rich in nutrients.

Anaerobic digestion• Anaerobic Digestion (AD) is a biological process that happens naturally

when bacteria breaks down organic matter in environments with little or no oxygen. It is effectively a controlled and enclosed version of the anaerobic breakdown of organic waste in landfill which releases methane. Almost any organic material can be processed with AD, including waste paper and cardboard (which is of too low a grade to recycle, e.g. because of food contamination), grass clippings, leftover food, industrial effluents, sewage and animal waste

Methods of Composting in HWM

• In-Vessel Method

In the In-Vessel Method, the organic material is composted inside a drum, silo, agitated bed, covered or open channel, batch container or other structure. The process conditions are closely monitored and controlled and the material is aerated and mechanically turned or agitated.

• Aerated Static Pile Method

The Aerated Static Pile Method involves forming compostable materials into large piles, which are aerated by drawing air through the pile or forcing air out through the pile. The pile is not turned.

. Windrow Method In the Windrow Method, compostable material is formed into elongated piles,

known as windrows, which are turned mechanically on a regular basis

Benefits of Compositing

• Compost allows the soil to retain more plant nutrients over a longer period.

• It supplies part of the 16 essential elements needed by the plants.

• It helps reduce the adverse effects of excessive alkalinity, acidity, or the excessive use of chemical fertilizer.

• It makes soil easier to cultivate.• It helps keep the soil cool in summer and warm in winter.• It aids in preventing soil erosion by keeping the soil

covered.• It helps in controlling the growth of weeds.

Recycling

Common recyclables

• Batteries• Clothing• Electronics disassembly and reclamation • Ferrous metals• Non-ferrous metals• Glass• Paper• Plastic• Textiles

Sources of waste

Source Type of generators Type of Wastes

Street sweepings, landscape and tree trimmings, general wastes from parks, beaches, other recreational areas, sludge

Agriculture Crops, farms, orchards, vineyards, dairies, feedlots

Spoiled food wastes, crop and animal wastes, hazardous wastes (e.g., pesticides)

Procedure for Plastic recycling

Recycling Process

This unit processes the first round of the process involves extrusion for lumps making. The lumps are then ground for size reduction and again extruded in pellets. Sorting is hardly ever required since the raw material is uniform quality, post industrial waste.

SCRAP → EXTRUDE (LUMPS) → GRIND → HSM (HEAT) → FEED EXTRUDER (CORDS) → PELLETIZING

MachineryTypes of Machinery1. Grinder 25hp 1 no2. High Speed Mixer 10hp 1 no3. Extruder 75mm 1 no4. Pelletizer 10hp 1 no

Capacity

• Installed Capacity 20 tons per month• Actual capacity 15 tons per month• Time taken to process one ton of plastic is 2 days.
