Two startups, Germany-based Lemki Robotix and Ukraine-based iScale3D, have developed a caravan made from more than 7,000 recycled plastic bottles. The interior includes a bed, a small kitchen and storage spaces. The outer shell weighs about 250 kg, the total vehicle weight is around 400 kg, and the walls are approximately 9 mm thick. The caravan accommodates three people and has a battery system that can be supplemented with solar panels. The project was first announced in 2024 and opened for pre-orders in 2026. The regular price is €21,500, with a pre-order price of €17,200. Production is scheduled to begin in mid-2027.
