Summer school in Italy using Big Hanna for their food waste

We believe it in creating systems that minimizes waste because it is a major tool in reducing CO2 emissions and fighting climate change. Treating waste close to the source raises social awareness. This is exactly what this school in Italy is doing with our Big Hanna composter – raising awareness.

The Municipality of Fiorano Modenese has applied for and received funding from Atersir, the Emilia-Romagna Territorial Agency for water and waste services, as a funding tender, ranking 16th out of 41 projects submitted, for the realization of the project ‘Compost kmzero’, within a series of municipal initiatives to combat waste and reduce waste. 

The Florentine project led to the purchase of a Big Hanna composter accompanied by a small communication campaign for local school pupils and their families.

The composter was installed at the Luisa Guidotti primary school in Crociale, to treat the food waste from preparation and leftovers of meals made for pupils and children attending the municipal summer camps, with the aim to spread knowledge and encourage the good practice of composting and raise the awareness of reduction of food waste in particular and of waste in general.

During the cutting of the ribbon in the presence of the municipal and scholastic authorities and a representative of Atersir, the operators at the school carried out the first load of food waste, while the 300 students involved in the project were distributed personalized boxes containing a small sample of compost and seasonal flower bulbs to plant as well as an illustrated leaflet on the advantages of composting and the operation of the composter.

The project estimates a potential reduction of 4-5 tons of waste per year. The installed composter can treat 75 to 100 kg / week, equal to about 10-15 kg per day of food waste produced by the school canteen as well as significant percentages of green waste originating from the maintenance of the school park. The estimated reduction is around 80% in volume and weight.

„The objective of the project – explains the councilor for the environment, Riccardo Amici, is to make the faculty, pupils, children and their families and the janitors of the school complex where the electromechanical composter will be installed, aware of the process of biological degradation of organic waste and use of the composter every day. It is considered in this way to inform and form, through events, dedicated moments and descriptive panels, even the families gravitating around the school, on the opportunity to carry out domestic composting, favoring virtuous behaviors to reduce food waste and reducing the volume of waste sent to the urban collection service, favoring the production of quality compost to be reused on the spot „.

With the installation of Fiorano Modenese, the Big Hanna machines delivered to all over Italy rise to 59 with as many as 35 already in full operation!

Recycling and Litter Prevention Community Grant Success Story: Akron Zoo

Text from: OHIO EPA – We want to share this success story with the Big Hanna readers!

Since 2011, the Akron Zoo has diverted more than 3.6 million pounds of organic waste from landfills. Previously, the zoo had been using an outside vendor who would collect their organic waste and take it to a composting facility. After experiencing changes with their initial organic hauler and increasing limitations on acceptable organic material, Akron Zoo decided to look for alternative solutions for their organic waste to help them reach their long-term goal of being a zero-waste organization. After evaluating their options, the Akron Zoo decided that the Big Hanna in-vessel composting unitwas best suited for their needs. The finished compost produced in four to six weeks, is used at the Akron Zoo for soil amendment and for landscaping through partnerships by groups like Keep Akron Beautiful and Let’s Grow Akron.

The community development grant from Ohio EPA’s Recycling and Litter Prevention Program (R&LP), along with match funds from Akron Zoo, were used to pay for the composting unit and other equipment. The Big Hanna unit will allow the zoo to compost 20,000 pounds of organic waste annually, including some typically difficult items to compost like vegetable flatware and animal waste. The Big Hanna and the building that encloses it serves as a model and educational opportunity for the zoo and its visitors to learn about sustainability. The zoo has hosted more than 200 tours of the facility, including institutions like Akron Public Schools, Kent State University and Goodyear. Akron Zoo has collaborated with other organizations such as the University of Akron by using some of their organic waste.

Through the R&LP community and litter grants, Ohio EPA offers funds to local governments of up to $200,000 per applicant for the collection and processing of recyclables. Communities and non-profits can also receive funding to implement litter collection events and tire amnesty programs. A 25 percent match from the applicant is required and the grant period is 12 months.

Reclaim ownership, RFID reader give a new possibility to compost separated collected bio waste locally

We believe that people want to take back responsibility and fight climate change locally and are willing to do so wherever they live, work or enjoy life. We believe in giving back the power to choose a system to where the system is going to be implemented. We believe that decentralized solutions are the best way to make our world sustainable. Our flexible small-scale systems allow you to control the input and by that the quality of the compost.

Big Hanna is now introducing an RFID reader which gives our customers a number of new opportunities:

  • A municipality can show that food waste is composted at source (and also how much!) which gives opportunity for EU funding when diverting food waste from landfill.
  • It is possible to give discounts on waste collection fees to citizens who compost their food waste, enforcing the ‘Polluter pays’ principle locally.
  • Visualize how much food waste is composted locally and by whom and use that information as a tool to minimize food waste which always should be the number one target.
  • Several houseowners can use one Big Hanna composter and share the operational cost based on usage.

For many years Big Hanna composter has been installed in housing areas where the customers have put their food waste directly into the Big Hanna composters.

By using RFID technology, we now make it possible to install a Big Hanna composter in public areas while controlling who can put the food waste into the composter.  

When installing a RFID reader on the inlet of the composter only persons who holds a valid RFID tag/card can put food waste into the Big Hanna composter

The touch panel log at what time and which tag/card opens the inlet. When the RFID reader is combined with a scale the logfile will also show how much food waste is composted by each tag holder. The log file can easily be downloaded to a USB stick or emailed directly from the touch panel.

A tag reader on the ‘Big Hanna composter’ inlet lid. The lid has a lock so the lid only can be opended when a valid RFID tag is shown.

Two tag readers can read the same tag. One RFID reader opens the entrance to the waste site and one RFID reader opens the lid on the composter.

Big Hanna composter makes it possible for a group of people to easily compost food waste in a densly populated area and the high quality and clean compost can be used directly in the neighborhood.

‘With the aim of developing a low cost, technically simple and high quality biowaste collection for organic waste.’

SCOW – Selective Collection of the Organic Waste in touristic areas – was a project funded by the EU between 2013-2015.

From SCOW website: ‘The aim of SCOW, funded by the ENPI CBCMED Programme, is to develop low cost, technically simple and high quality biowaste collection and recycling models in territories with touristic areas and agricultural activity. SCOW wants to build up a sustainable, innovative and local treatment of the biowaste in decentralized small-scale composting plants, developed essentially in agricultural holdings situated near the biowaste production areas in the partners ’territories.’

Participants were entities from countries around the Mediterranean Sea and among the participants were ‘Agenzia di Sviluppo Gal Genovese (The development Agency Gal Genovese)’. They choose as a part of their project to install three Big Hanna composters in the Genova area, in City of Ne, Villaggio del Ragazzo Institute and at the Marco Polo Institute in Genova.

Agenzia di Sviluppo Gal Genovese have made a film about the project, but even if the project took place a few years ago it still is most relevant information when making decision on how convert biowaste to high quality compost and closing the loop by using the compost for improving the soil.

‘The success story of BERCA BRAND and the Madrid municipality of El Boalo.’

Big Hanna and BERCA BRAND got an article in ”Equipanmiento y servicios Municipales No 187, 2019
Freely translated from the Spanish Original 😊

Sustainable solutions for the municipal management of organic waste.

The municipality of El Boalo-Cerceda-Mataelpino, located just 50 km from the state capital and at the foot of the mountains that make up the National Park of the Sierra del Guadarrama, has long been famous for the innovative nature of its policies and especially in terms of waste management, in a clear example that sustainability and innovation should occupy a prominent place in municipal policies.

In July 2016 the municipality of El Boalo, with Blanca Ruiz at the head of the Department of the Environment and the waste management service, decided to overturn the municipal waste policy and began the remunicipalisation of the service collection, to date in the hands of a company, taking control of the waste management with the proper means of the municipality and a clear ecosocial commitment. For this, the „Zero Waste” strategy were launched, awarded by the XXVII edition of the National Culture Viva Awards, in which it is distinguished with the award for the best locality for its proposal for circular economy and „zero waste”.

This strategy includes various proposals aimed at avoiding the generation of waste that cannot be managed directly in the municipality, for which actions are being implemented up to now, such as the use of a herd of Guadarrameñas goats as a means of treating the remains of pruning that are produced by the municipality or the use of “avicomposteros” in which hens are responsible for the treatment of 4,000 kg per year of biowaste produced in schools, actions with a clear component of environmental education.

But although such original actions have been responsible for the important visibility of the El Boalo project, they are not the only ones developed by this municipality of just over 7,500 inhabitants, the strategy of the municipality directed by Javier de los Nietos has a long history, deeper and consolidated based on four fundamental pillars, the „zero waste”, the „circular economy”, environmental education, and agroecology.

To this end, it now has more than 250 individual and community composters, door-to-door collection, recovery of equipment and tools and they work on new projects such as the collection of domestic oils for the production of biodiesel, which has led them to be distinguished last November with the VIII CONAMA prize (National Environmental Congress) for the Sustainability of Small and Medium Municipalities, besides being declared the „First Zero Waste Municipality of Madrid” by the Zero Waste Europe entity.

On this occasion it stands out again with another pioneering initiative, the start-up of the first automatic composting installation in CAM with BIG HANNA technology that will allow the composting of the bio residue collected selectively in the municipality in an automatic, fast way, controlled and without any external interaction, free of odors, insects, birds and other inconveniences that traditional systems have.

The BIG HANNA technology, of Swedish origin and distributed in Spain by BERCA BRAND, has been developed since 1991 and currently has more than 1,000 installations throughout the world and allows applying the most advanced technology to something as natural as the composting of biowaste. The biological process is developed inside the machine in a continuous and controlled way, which allows to develop the thermophilic, mesophilic and maturation phase inside the digester itself. This process can last between 6 and 10 weeks, which guarantees that the compost can be used safely, free of odors and pathogens. During this time, organic waste is reduced to 90% of its volume.

The BIG HANNA composting machines operate almost completely autonomous without hardly requiring the intermediation of personnel. The remote control of the machines allows access to the touch screen from remote or even from a smartphone or a tablet, receiving any alarms that may be caused as a result of a failure in the process, as well as reprogramming at a distance, the working times of aeration and rotation, thus correcting anomalies in the process.

The touch screen shows the temperature record and the settings of the programming, the inputs and outputs when recording, as well as the alerts and the power consumption. The log files can be downloaded to a USB stick, memory card or accessed remotely via the internet.

Thanks to this remote control, the automation of the process (low labor cost) and the low energy consumption, the operating costs of this installation are very low.

BERCA BRAND proposes a new model of bioremediation management by decentralizing its treatment through a strategic distribution of mini-plants in a territory, thus avoiding unnecessary transport of the largest and heaviest fraction contained in the waste. Its purpose is to bring the treatment closer to the sites which produces the waste.

Here the application of circular economy strategies is so booming and in view of the need to reach the aforementioned 2020 objectives by the municipalities, BERCA BRAND AND BIG HANNA contribute to a real change in line with these objectives.
