Baseline levels of microplastics in agricultural soils obscure the effects of additional microplastics from recycled fertilizers

Microplastics and Nanoplastics
Digestate from the recycling of various organic wastes in biogas plants is widely used as organic fertilizer for agricultural soils. Organic fertilizers contribute to microplastic loads, but it is not well constrained how they contribute to the overall ...

Solid Grain Waste Digestate as a Peat Substrate Amendment for Tomato Seedlings: Effects of Direct Sowing and Transplanting on Growth and Photosynthesis

Agronomy
The quality and productivity of tomato (Solanum lycopersicum L.) crops largely depend on the quality of the seedlings used for cultivation. Several factors, including cultivation strategy, fertilization practices, and abiotic and biotic stressors during ...

Moderate thermal post-treatment of digestate to improve biomethane production from agricultural- and food waste [Elektronisk resurs]

The aim of this study was to assess the feasibility of moderate thermal treatment (70 ◦C for one hour) of digestate in combination with post-digestion targeting residual biomethane potentials from three full-scale biogas plants digesting food waste (FW),

Nutrient Recovery From the Liquid Fraction of Digestate by Clinoptilolite

, 2017
The direct application of the liquid fraction of biogas digestate to agricultural fields as a fertilizer may result in practical and environmental problems. Concentrating nutrients onto clinoptilolite and subsequently using clinoptilolite as a fertilizer
