In Collaboration With


Biogas is a mixture of different gases produced by the breakdownof agricultural waste, manure, municipal waste, plant material,sewage, green waste, or food waste, in the absence of oxygen

WHAT IS BIOGAS?

Biogas produced is further purified and processed, it is calledbio-compressed natural gas (bio-CNG). It is similar to natural gasin terms of its composition and properties, and is a cleaneralternative to fuels such as petrol and diesel

WHAT IS BIO-CNG


The global biogas market can be segmented by application into electricity and heat generation, vehicle fuel, and others. Other application includes supply to a natural gas pipeline and domestic use. Electricity and heat generation segment is expected to lead the overall global share over the forecast period. Demand for upgraded biofuel is presumed to increase in the recent future owing to the low cost of fuel and compliance with stringent vehicle emission regulations.

GLOBAL BIOGAS PLANT MARKET: OVERVIEW

Global Biogas Market to Reach $50 billion by 2026

Global biogas revenues are expected to grow at a steady 6.5% CAGR from nearly $24.5 Billion in 2015 to around $48.8 billion in 2026, according to a new report from Future Market Insights


MARKET TREND

In India, bio-CNG has immense scope, specifically as a replacement for the more widely used CNG and liquefied petroleum gas (LPG). Bio-CNG can cater to diverse segments of the market with applications in commercial (hotels, canteens, bakeries and resorts), industrial (glass and ceramic, metal processes, cement and textiles) and automotive (public transport and private vehicles) processes.

INDIA


BIO-CNG POLICY

❖ It is planned to roll out 5,000 CBG plants across India in a phased manner, with 250 plants by the year 2020, 1,000 plants by 2022, and 5,000 plants by 2025.

❖ Expected production of 15 million tonnes of CBG per annum, which is about 40 per cent of current CNG consumption of 44 million tonnes per annum in the country.

❖ Expected investment of around Rs 1.7 lakh crore and to generate direct employment for 75,000 people and produce 50 million tonnes of bio-manure for crops.

❖ Aimed at providing a sustainable fuel alternative that would benefit vehicle users, farmers and entrepreneurs.❖ The 1,500-strong CNG stations network in the country currently serves about 32 lakh gas-based vehicles. The Working Group on Biofuels,

set up under the National Policy on Biofuels 2018, is in the process of finalising a pan-India pricing model for CBG.❖ The entrepreneurs would be allowed to separately market other by-products from these plants to enhance returns on investment.❖ The National Policy on Biofuels, 2018, emphasised on active promotion of advanced biofuels, including CBG. The Government had

launched the GOBAR-DHAN (Galvanising Organic Bio-Agro Resources) scheme earlier this year to convert cattle dung and solid waste in farms to CBG and compost. The scheme proposed to cover 700 projects across the country in 2018-19.

❖ CBG networks can be integrated with city gas distribution (CGD) networks. Later, the retailing from OMC fuel stations could be injected into CGD pipelines, too, for efficient distribution and access. The potential for CBG production from various sources in India is estimated at about 62 million tonnes per annum.

BIO-CNG FEEDSTOCK

❖ One of the leading oil corporation in India is planning to set up 100,000 litre per day ethanol/ BIO-CNG plant using rice straw as feedstock.

❖ The $124 million plant is hoped to provide a market for rice straw for local farmers to reduce the burning that plague’s the region’s air every year. Close to 14% of paddy straw (>120 million tons) produced is burnt.

PRESS MUD

❖ India produces around 350-400 million tons annually and in season 2016-17 it seems near to 320 million tons 3.6 to 4 % of press mud is get out of 1 tons of sugarcane.

❖ India produces annually approximately 10-12 million tons of press mud.❖ Rich in methane and is the major source of biogas❖ 1 Ton of Press mud, waste from sugar-cane mills, would also yield about 80–100Nm3

of Raw Biogas

TECHNICAL DIFFICULTIES OF BIOGAS CONVERSION FROM FIBROUS SUBSTRATES


There is a need for a pre-treatment approachto disintegrate the crystalline structure and speed up the hydrolysis process.

To realize the hydrolysis process with organic polymer transformation to simple and small molecule mass, such as sugar.

Ligno-cellulosic materials in their raw form, due to the structural features mentioned,are highly resistant to anaerobic digestion

TECHNICAL DIFFICULTIES OF BIOGAS CONVERSION FROM FIBROUS SUBSTRATES


TECHNICAL TROUBLES IN THE PRACTICAL PROJECTS, HAPPENED IN YOUR AD PLANTS

❖ Long decomposition time, For maize silage needs HRT 50-90days, For dry straw, required more longer HRT, huge digester volume required

❖ Low biogas conversion rate, particularly less gas yield rate for pure dry corn straw

❖ Easily form the floating layer, further hard scum layer, lead to the final failure of AD system

❖ To avoid risk of floating layer, high power capacity agitator with long operation time, high operation cost

❖ Difficult inlet and outlet of digester, pump and pipe easily got clogged, high maintenance cost

Our hydrolysis unit provides an aerobic and anaerobic mixed florawith different biochemical reactions:

❖ Support aerobic microorganisms to rapidly secrete large amountsof hydrolase to convert cellulose into soluble sugar

❖ Support anaerobic microorganisms to produce small amounts ofalcohol

❖ Support aerobic production of acetic acid❖ Supports the internal disintegration of molecular chains and

reduces material viscosity while rapid polymer degradation

In the conventional system, the hydrolyzed microorganism is adedicated anaerobic microorganism, and its living environment islimited by the methanogen, and the amount of the enzyme capableof acting on the cellulose is small and the activity is low.

SEMI-AEROBIC HYDROLYSIS COMPARED WITH TRADITIONAL PROCESS


❖ No chemical agent added, lower operation cost

❖ Hydrolysis completed within 1-2days, hydrolysate input to the digester and complete the biogas conversion within 25days

❖ Volume of digester decreased, lower investment

❖ Easily pumpable and less floating layer, lower agitating power consumption

❖ Possible for gas conversion of pure dry straw, deeply utilize gas yield potential

❖ A higher CH4 concentration is obtained, as some CO2 released from hydrolysis

❖ Many inhibiting chemicals can be broken down in hydrolysis(such as phenols, Ammonia etc), keeping the digester(methane

production) running more stable.
