maybe if you have space you could make like a separate "animal products" compost bed and use the compost from it to fertilize flowers or something? i think it's fine to "waste" food when the alternative is eating dead things or byproducts of industrial SA, but if you want to avoid waste anyways i think this could work. i suppose the ethics of this could be questionable, but I think if you avoid using it to grow produce and just use it as a simultaneous burial/enrichment of the local ecosystem it would be fine
