ProfiKomp® Breathable Drum Composter showcasing its innovative design.

The inception of the drum composter was driven by a culmination of factors. At its core, our journey into its creation was steered by the rich expertise garnered over two decades of dedicated work in the field of industrial composting technologies. This profound experience, earned through relentless innovation and development, served as the foundation upon which we embarked on a transformative path. In recent years, this reservoir of knowledge has been artfully directed toward crafting technologies and equipment tailored for smaller capacities.

Who Can Benefit from This Solution?

The drum composter offers a versatile solution tailored to the needs of various sectors. It caters to smaller communities, residential groups, educational institutes, as well as catering units and hotels alike, allowing them to efficiently recycle their compostable waste. Waste management service providers and facility operators, entrusted with waste management tasks, can also find value in the drum composter as it enables on-site, professional, and cost-effective biowaste recycling, eliminating the need for transportation. Likewise, small farms and park and garden management companies are also potential users of this innovative technology.

Operating innovative industrial quality solutions

The equipment is a revolving drum with two chambers with a corrosion-resistant perforated surface equipped with a permeable membrane cover. In one of the two chambers, the waste is collected and pre-treated, while the intensive composting phase takes place in the other one. The drum composter is separated into two chambers, which makes it possible for the two phases of the waste treatment to take place at the same time. While in one of the chambers, the biowaste is collected, in the other one the waste that has already been collected goes through the composting process. The temperature of the chambers can be measured separately, which makes monitoring possible. The cycle of the intensive composting process lasts four weeks, at the end of which the final product is a hygienic, matured compost. After four weeks and when the temperature drops below 40 degrees the final compost product is screened, and one chamber can be used to start the collection process, while in the other chamber, the intensive composting can restart. The volume of the two chambers is 1000 l together, which means a net 750 l of useable capacity; therefore the composting drum can treat up to 5000 kg of waste every year. As a result of the revolving movement, the materials inside are mixed continuously while their sizes are also decreased, leading to a looser and more homogeneous structure, while the compost can mature in a smooth process. Mixing the material requires minimal energy and can be efficiently carried out with a revolving bar or even with an electronic engine. The application of the special, breathable membranes ensures the air requirements of the composting process are met. Therefore, it is possible to compost quickly, efficiently, and in an odorless way. Due to the membrane covering, the odor emission of composting is reduced by 90 percent. The monitoring of the optimal composting process is carried out based on temperature measuring with software, optimized for smartphones. The ProfiKomp® Wireless Temperature Sensor /WTS/consists of a wireless temperature probe placed in the drum composter and a smartphone-optimized application. The system was developed in a simple and easy-to-understand way to provide the most important data about the composting process. As a result, hygienic, good-quality final compost products can be produced. Recyclable and Non-recyclable Wastes The quality of the compost that is produced is largely influenced by the type and composition of waste that enters the composter. The more types of organic waste free of foreign materials (preferably dry and moist materials mixed together) enter the composter, the more complex and possibly better quality the mixture will be – however, it is very important that only biodegradable wastes are put into the equipment.

Effect of Waste Composition on Compost Quality

The compost’s quality is significantly shaped by the nature and makeup of the waste introduced to the composter. The diversity of organic waste, devoid of contaminants, particularly a blend of dry and moist materials, contributes to a more intricate and potentially higher-quality compost mix. It is crucial, though, to exclusively include biodegradable waste in the composter to maintain its integrity and effectiveness.

Compostable materials include a wide range of organic waste such as fruit and vegetable scraps, coffee grounds, eggshells, yard waste like leaves and grass clippings, and even small amounts of paper and cardboard. These materials can break down naturally and contribute to the nutrient-rich compost. On the other hand, non-compostable items such as plastics, metals, glass, and synthetic materials should never be introduced to the composter. These materials not only hinder the composting process but also introduce pollutants that can degrade the quality of the final compost. It’s essential to maintain a strict separation of compostable and non-compostable materials to ensure the effectiveness and sustainability of the composting process in this system.
