In DGE I especially value the principle of ‘freedom under responsibility’ – It’s a big part of our work culture.

Ieva Sveikauskaitė

Environmental Specialist

M.Sc. in Engineering

Acoustic, air and odor pollution are important, ever-increasing forms of environmental pollution. As road and rail traffic flows intensify and industry develops, so do contaminated areas. In order to reduce, control and ensure air, odor and noise pollution in the environment, I have been working with dispersion modeling programs for 5 years, which allows us to assess the current situation and improve it by protecting each of us. I prepare noise, air and odor pollution assessment reports, propose and analyze measures to reduce pollution. When communicating with customers, I always try to listen to their needs, but also to offer more sustainable solutions that will gradually contribute to the improvement of the general state of environmental pollution.

I have been working at DGE Baltic since 2015. In this company, I grew up as a specialist and gained all the knowledge baggage I have now. Here I worked with the biggest and most important – for me, environmental projects both within Lithuania and abroad. I hope we will grow together for a long time with a great team!




Aleksandras Kirpičiovas

Public Health Expert

M.Sc. in Public Health

At the beginning of my career since 2000, I have been interested in occupational medicine and occupational pathology. For these 5 years I have been evaluating the impact of work environment factors on workers’ health, participating in a team of experts in the process of research and diagnosis of occupational diseases.

For the last 15 years, my main field of interest is environmental medicine, since then I have been conducting public health impact assessments, participating in EIAs, environmental audits, designation of sanitary protection zones, and other assessments in the fields of agriculture, energy and manufacturing.

Since 2015, working at DGE, I have been able to realize my knowledge and experience. In my daily work, I am dealing with the assessment of air pollution, noise and odours in the environment in order to determine the compliance of these environmental factors with the requirements of legal acts and the potential impact on health – both the population and workers. In a team with environmental specialists who model these environmental factors, I am looking for opportunities to reduce the negative impact on the environment and public health.
