"My collaboration with Lavaris began completely by chance. Mr. Director Karraá, like myself (despite our age), enjoys playing football. After many months of regularly playing together, he once asked me: “I know you've been working with fragrances for a long time and that you also collaborate with manufacturers in this field. Would it be possible, on the contrary, to completely eliminate the scent or odor from a particular material?” He was right on both counts – our group, together with our colleagues from Aroma, holds the Czech national record for the longest continuous collaboration between an academic institution (UCT Prague) and an industrial company (Aroma Prague), which has now lasted uninterrupted for over 50 years. We solved the task quickly, in an environmentally friendly and cost-effective way. At the same time, the solution adds value to what was previously a troublesome waste material – now serving as an interesting raw input for other types of production. We are genuinely looking forward to further collaboration with Lavaris!"
Prof. Libor Červený, DrSc. – University of Chemistry and Technology, Prague (UCT Prague)

"LAVARIS is not only a technological innovator focused on highly specific materials often deemed non-recyclable by other companies, but also a strong advocate for the crucial topic of ecological design.
Through its Reborn Design competition, LAVARIS promotes a vital perspective: that up to 80% of a product’s environmental impact can be determined already during its design and manufacturing stages. With this, the company is spearheading an essential public campaign in the Czech Republic—one that has long been missing.
I truly value the work of the entire team, which I’ve been following closely since the early days of INCIEN. LAVARIS is also actively involved in numerous research projects with Czech academic institutions, which not only leads to important discoveries but also strengthens the credibility of the company’s work. For this, it has received various awards, including recognition in prestigious government-led competitions."
Ing. Soňa Klepek Jonášová, Founder INCIEN

"The product eco-design studio Plastenco has maintained a long-term collaboration with the technology company Lavaris, thanks to their proven professionalism and ability to respond flexibly to project challenges.
Together with the Faculty of Architecture at the Czech Technical University in Prague (CTU FA), we are working on a research project focused on developing technology for large-scale 3D printing using recycled plastics. The partnership with Lavaris is essential for fulfilling Plastenco’s business goals—through this collaboration, we are able to develop new products based on the principles of the circular economy. Another key area is our joint organization of the student challenge Reborn Design, which has been running since 2022. Lavaris’ technologists are capable of working even with secondary materials, which students use to design innovative products."
Jitka Hvězdová, Founder & CEO PLASTENCO

"With its research capacity and wide range of technologies, Lavaris is an excellent partner for exploring material recovery solutions for waste processing. I highly recommend the company."

"Our collaboration with LAVARIS s.r.o. has been extremely beneficial. Professionalism, responsiveness, and a constructive approach were a natural part of the entire cooperation—from defining the brief focused on the reuse of various types of secondary raw materials to proposing a technical solution tailored to our needs. The expertise and technical skills of the LAVARIS team in the field of material recycling have supported us in creating the necessary conditions to fulfill the mission of the Research Institute for Building Materials (VÚMZ), where “responsible research” is our path and a “safe future” our shared goal. We greatly value our partnership with LAVARIS s.r.o. and, based on our experience and research focus, we look forward to continuing our cooperation in developing new solutions that contribute to sustainable development."
Ing. Zdeněk Krejza, PhD. – VÚSH (Research Institute of Building Structures)

I would like to share my positive experience working with Lavaris. I personally find the collaboration very inspiring—especially due to the strong connection between academia and industry. Together, we focus on current R&D topics in the field of material recycling and explore new pathways toward sustainability. I am convinced that new technologies and materials will be in high demand in the future. I truly appreciate the friendly and professional approach of the company, and I’m glad we can jointly contribute to advancements in material processing and reuse.

"Lavaris and George Karra’a are pioneers in several areas related to recycling and the secondary use of raw materials.
In recent years, we have supported some of their innovative projects and technologies, and we continue to follow with interest how they are gradually finding their way to customers and the market. The company’s products have the potential to significantly contribute to sustainability and reduce both material and energy demands in the economy and industry—not only in the Czech Republic."
Pavel Jovanovič – CEO of the Central Bohemian Innovation Center

"We would like to express our satisfaction with Lavaris for their innovative approach to drywall recycling. Thanks to their innovative methods, we have been able to start using recycled construction waste in our drywall production, thereby making a significant contribution to environmental protection. The cooperation with them was very professional from start to finish, and their team was always ready to provide expert advice and support. We appreciate their commitment to sustainable development and warmly recommend Lavaris to anyone seeking an innovative partner in the field of construction material recycling."
Ing. Radomír Kamler, Operations Director SAINT-GOBAIN

"We have been cooperating with Lavaris for over 10 years. The main area of collaboration is rubber recycling, where the company was able to produce active rubber powder of any desired granularity from supplied rubber granulate. The cooperation was not limited to rubber grinding but also included milling of other materials usable in the rubber industry, such as nutshells. We highly value our cooperation with the company for their willingness to seek and find solutions to our and other requirements. In this, Ing. George Karra’a plays an exceptional role. His creative activity goes beyond the usual level and has always been beneficial for us. It is no coincidence that this cooperation has resulted not only in interesting publications but also in solutions for technology vouchers and recognition by the Ministry of the Environment."

"We have been successfully cooperating with Lavaris s.r.o. since the beginning of 2023, when we established a business partnership as part of the Reborn Design competition for young designers. Since then, we have been working together on waste recycling programs related to our business and products. We especially appreciate Lavaris’s technological sophistication and the innovative ideas they bring. In today’s world, where the transition to a circular economy is almost a necessity, the ability to recycle and transform waste into secondary raw materials is crucial for us. Lavaris s.r.o. has fully met our expectations in this regard and has become our long-term partner."

"After more than six years of experience, I would characterize Lavaris like this: A company where content is just as important as form, and the result is the most important of all. A place where ways to reach the goal are sought, and flexibility is balanced with a systematic approach. In summary, Lavaris fulfilled everything we agreed upon, even though it seemed like science fiction at the beginning. Recycling here takes on a tangible and usefully pragmatic character."
Ing. Miroslav Nyč, Head of Product Management, KNAUF Prague
