It gives us great pleasure to invite you to discover IES

BIOGAS, inspired by the awareness that the change in

the world cannot be stopped, but only embraced and

seized as an opportunity.

Driven by this motivation, we embraced new

technologies and new areas of application, while

expanding into the world. We are investing in renewable

energy and implementing the “green and circular

economy” by offering comprehensive, cutting-edge

solutions. Today we are looking forward to the future,

certain that we can win the trust of those who do not

yet know us and that we shall continue to deserve the

confidence of those who have chosen and supported

us over the years.

WE WANT TO SHARE OUR VISION

OF SUSTAINABLE DEVELOPMENT

IES BIOGAS is an Italian company

specialised in the design,

construction and management

of biogas and biomethane plants.

IES BIOGAS’ watchwords are elasticity and measure, applied by adopting an objective professional approach to the analysis of different possibilities and always proposing the best solution to our customers through a depth analysis of the company and its local context.”

IES BIOGAS’ goal has always been to build installations that fully meet the needs of the market in terms of construction and safety but also of management and automation. This is why the architectural design and working drawings, the piping systems, the electrical and hydraulic plants as well as the software, are entirely developed in-house, guaranteeing that our customers always receive a top quality, ”customized” product. Our team is made up of men and women who strive towards continuous improvement: highly skilled biologists, engineers, agronomists, IT specialists and process experts with consolidated accomplishments, who guarantee innovative, efficient and reliable solutions and installations.

Founded in 2008, IES BIOGAS immediately began playing a key role in the agriculture industry through the construction of nearly 200 plants in just a few years. Through Biogas24, our division dedicated entirely to plant servicing and management, IES BIOGAS has shown that we always stay close to our customers, enabling our plants to reach significant levels of performance. After consolidating a leadership role in the agricultural sector through IES Agri&Farm, in 2015, we decided to diversify by entering the industrial sector through the creation of IES Waste, a new division dedicated to the construction of installations for the waste sector. Later on, the company develops IES FoodIndustry, a division to enhance the byproducts and the food process waste, in order to convert them into energy.

The need to acquire new customers has led IES BIOGAS to look beyond national borders and to start a process of internationalisation in other European countries and overseas. Today, our company is building plants in Argentina, Korea, Croatia, Serbia and Poland, and it can count on a significant global sales network. To be closer to our customers and to the local territories and to guarantee top-level services, our offices in Buenos Aires and Jakarta are already operative and the branches in Beijing and San Diego will be opened soon.

Since July 2018, IES BIOGAS has become part of the Snam Group, the European leader in natural gas infrastructure management. This operation has given IES BIOGAS the opportunity to be supported by the Snam Group, further corroborating our leadership in the agricultural sector and developing our presence in the industrial sector, especially in the production of biomethane. IES BIOGAS will continue to operate with the utmost professionalism at the service of the market, providing technologically advanced, flexible solutions and projects, tailored to each customer.

Finally, IES BIOGAS’ proven reliability, experience and solidity are enabling our company to take on a new role, presenting itself on the market to private and public investors as General Contractor, with EPC (Engineering, Procurement and Construction) and EPCM (Engineering, Procurement, Construction and Management) functions, thus offering our customers the utmost assurance of quality, execution time and performance.

The biological purification strategy is based on the natural metabolism

of a series of bacterial species that digest these compounds in order

to grow; nature has developed a huge variety of bacteria suited to the

widest range of environmental conditions. In biological purification

plants, techniques are applied that stimulate the growth of the

desired bacterial species by replicating the conditions to where they

are best suited.

The most widespread biological technique, known as the “activated

sludge”, uses bacterial species whose metabolism (similar to that of

more advanced living beings) is based on the oxidation of carbon;

they therefore breathe oxygen and are known as aerobic species.

These species efficiently metabolise carbon within a wide range of

temperatures, and techniques have also been developed to allow

them to reduce nitrogen levels.

Scaling up this technique involves consuming large amounts of

energy, since the bacteria must be supplied with oxygen. Based on

almost a hundred years of experience, we know that no less than 1

kWh is required to treat the carbon corresponding to 1 kg of COD.

Moreover, due to the metabolic efficiency, this treatment produces no

less than 200 grams of bacteria (sludge) to be disposed of.

The families of bacterial species known as anaerobic are less

common, primarily because they are efficient within a more limited

temperature range (30-55°C). Their metabolism is based on the

reduction of carbon, so they do not need to breathe oxygen. Their

metabolism is also much less efficient, so much so that they grow

by less than a tenth compared to aerobic species using the same

amount of carbon. However, their metabolism does produce a

significant quantity of methane.

The anaerobic technique is used less widely for two objective

reasons: firstly because it requires temperatures above 30°C and a

sufficient concentration of carbon; but above all because in the past,

the low cost of energy combined with a lack of awareness around

using it efficiently and the low cost of sludge disposal favoured the

technique that required a lower initial investment. Today, however,

the rise of operating costs is making it increasingly necessary to

minimise the use of aerobic techniques for carbon reduction.

Today, it is essential to use all plant engineering strategies in

the biological purification process in order to apply anaerobic

technologies for carbon reduction.

In anaerobic conditions, a reduction of carbon corresponding to 1

kg of COD (which requires at least 1 kWh in aerobic conditions, as

we have seen) involves negligible electricity consumption, while it

produces a quantity of methane corresponding to almost 3.5 kWh

of chemical energy.

The energy balance is also extremely favourable for the production

of biomethane: net of heat requirements, energy consumption is less

than one fifth of the energy produced.

AEROBIC AND ANAEROBIC: A PERFECT SYNERGY

Thanks to the constant streamlining of production processes, the food industry now wastes on average just 2% of the processed product,

which is mostly made up of residue transported by the water used to clean machinery and premises.

However, the enormous scale of food production makes even this small percentage a huge source of pollution by organic compounds

(mostly carbon, but also nitrogen and phosphorus). For a long time now, biological technologies have been developed

to purify this water before pumping it into bodies of water.

Infusion techniques produce considerable waste which is partly hydrolysed by the process itself; this can still be used in anaerobic

digestion. Factories that process fruit to produce purees and juices release effluents with high levels of pollution from dissolved sugars.

Specific anaerobic technology exists based on biomass that conforms to granular colonies; this technology allows purification costs

to be reduced by 90%.

THE FOOD INDUSTRY:NEW ENERGY POSSIBILITIES.

BEVERAGE INDUSTRY

Waste and effluent from potato processing are particularly suitable for anaerobic treatment: the solid fractions discarded during tuber

preparation on the one hand and the starch dissolved in effluent on the other allow for a very favourable purification process using

anaerobic treatment. In these processes, the anaerobic digestion of waste and residue combined with cogeneration techniques can

generate renewable energy that accounts for 20-30% of electricity consumption.

The food and beverage sector is where biogas and biomethane plants really come into their own: thanks to the IES FOODINDUSTRY division, by-products and waste from food processing are recovered and transformed into energy, offering a new source of income.

Our anaerobic fermentation technologies are ideally suitedto the food industry for a range of reasons:

1) they produce by-products which are useful from financial and environmental standpoint;2) they consume heat and electricity: the waste, through the production of biogas, allows energy to be created, therefore providing new earnings as part of a circular economy.3) the use of the by-products offers a great opportunity to promote biomethane.

We offer the best anaerobic solutions for: • Beverage industry; • Potato and tuber industry; • Confectionery industry; • Beer industry; • Biodiesel production. • Meat and fish industry;• Dairy industry;

Slaughterhouses and fish processing facilities release effluents whose organic load can be greatly reduced through simple coagulation

processes and the separation of solid fractions in the form of primary sludge. This sludge can have considerable disposal costs but can

also become a significant resource if treated with anaerobic technology. In slaughterhouses, faecal and rumen residues from cattle

are also eligible sources for biogas production. In the meat industry, purification costs can be totally eliminated by applying these

strategies alongside cogeneration techniques.

DAIRY INDUSTRY

Dairy production creates waste and by-products containing an organic pollutant load that cannot possibly be handled with aerobic

techniques. These enormous amounts of material must be disposed of daily to avoid halting production; for this reason, dairies are often

forced to dispose of this waste at specialist centres at considerable cost, especially in the south of Italy. Anaerobic technology has been

developed that can treat this type of flow, turning costs into energy production revenue.

Medium-sized dairies (> 20,000 litres of milk a day) can eliminate their electrical costs and halve their heating costs.

DAIRY INDUSTRY

The residue collected when packaging lines are cleared, residue from the preparation of raw ingredients, creams and pastes left over when

machinery is cleaned, non-compliant products, and fats and sugars transported by washing water: when treated anaerobically, these

sources can produce between 10% and 20% of the total energy consumed by the factory.

CONFECTIONERY INDUSTRY

Breweries release effluents contain starches and dissolved sugars, 90% of which can be cut down with anaerobic granular sludge

technology, in this case a primary treatment is done on the effluent which is then refined in an aerobic system with activated sludge.

The synergy between anaerobic and aerobic technologies allows to reduce to zero the costs of effluent treatment.

BEER INDUSTRY

Biodiesel is made by producing ethanol through the distillation of fermented cereals; when the distillation residue, called distillers grains,

cannot be used directly for fertigation, it can instead be put to good use in anaerobic digestion. The quantities of gas produced cover

more than 25% of the massive heat consumption of these factories.
