This article examines how Lean principles can be integrated into public-private partnership (PPP) projects to promote effective reconstruction and sustainable infrastructure development in postwar Ukraine. Driven by the urgent need to rebuild, Ukraine faces the challenge of not only rehabilitating its infrastructure assets, but also ensuring compliance with European Union standards and global sustainable development goals. The study explores the theoretical underpinnings of Lean manufacturing and its applicability to infrastructure PPP projects. A mixed method approach, including document and literature review, case studies, expert opinion and SWOT analysis, was used to identify opportunities for improving project implementation and resource allocation. The results show that the Lean concept can save costs, promote multi-stakeholder collaboration, and optimise procedures at each stage of the PPP infrastructure project lifecycle. Overcoming regulatory hurdles, attracting private investment and reducing political and economic uncertainty, are necessary ingredients for the successful implementation of Lean-based infrastructure PPP projects.

The history of the founding of the Kaliningrad region, as part of the USSR, is one of the most vital issues for Kaliningrad historians. Since the collapse of the Soviet Union, this problem is actively investigated.

Unique findings, wells with wooden constructions and buckets made of lime bark in them, were detected recently in the Lieporiai 1 settlement near Šiauliai (in northern Lithuania). These objects were parts of an iron smelting site dated to the fourth to eighth centuries. Reconstructions of the well and the technique of producing lime bark buckets were made by B. Salatkienė and A. Šapaitė. A detailed description of the artefacts and their environment constitutes the first part of this paper, and the technique of reconstruction and producing lime bark buckets forms the second.
