in general, agreed on the point about coffins, and using land just for butial into perpetuity is not a great tradition.

If and where it’s just about the use of a box, and/or about the using of land space solely for burial, then one other option they can adress bith of these is ‘green conservation butkal’.

The land is used for nature and ecosystem restoration and conservation at the same time, and there is no box/coffin required at all. They can also sometimes be less expensive than conventional burial (with the box and the embalming and so on) or even conventional cremation. Some more about the subject at:
