The process, known as resomation, uses a mix of potassium hydroxide and water to break down human remains in what is billed as a more sustainable option.
The British company Resomation, which supplies the equipment, claims the process produces a third less greenhouse gas than cremation and uses a seventh of the energy. Anti-apartheid campaigner Archbishop Desmond Tutu chose the process for his funeral arrangements in South Africa - he died in late 2021.
