Managing dairy excreta as slurry can result in significant emissions of ammonia (NH3) and greenhouse gases (GHGs) during storage and thereafter. Additionally, slurry often has an imbalanced nitrogen (N) to phosphorus (P) ratio for crop fertilization. While various treatments exist to address emissions …

Providing equitable food security for a growing population while minimizing environmental impacts and enhancing resilience to climate shocks is an ongoing challenge. Here, we quantify the resource intensity, environmental impacts and nutritional output of a small (0.075 ha) low-input subsistence Mediterranean …

Source Segregation (SS) is a novel strategy in dairy housing that can reduce emissions and separate organic matter and nutrients more efficiently than traditional slurry solid-liquid separation. The anaerobic digestion (AD) methane yield of the SS fractions, however, is unknown. We aimed at unveiling …

The main objectives of this review were to: (1) review different methods/techniques to assess gaseous N-losses from manure (2) review N-gaps, attributed to dinitrogen loss as the difference between directly measured N compounds summed as total N loss and indirectly measured N loss through a mass balance …

Biopolymeren vormen een potentieel interessant alternatief voor conventioneel op olie gebaseerde polymeren, omdat zij geen fossiele grondstoffen gebruiken voor de productie. Daarentegen is het productie procedé afhankelijk van energie en toevoegmiddelen die weer bijdragen aan het verbruik van energie …

Worldwide, plastic cups are used for serving drinks. Some typical examples of large-scale consumption are large concerts and festivals. As a part of the BIOCAS project, which focusses on the valorization of biomass through various routes, a PHA biobased festival cup was developed and created to reduce …

The present work aims at providing broader insight into the environmental impact of milk production by comparing greenhouse gas (GHG) and nitrogen (N) emissions of milk production among the intensive and extensive dairy farming systems from production and land-use perspectives. Three dairy farms in the …

In heldere en concrete taal wordt besproken wat duurzaamheid is en waar het toe dient, met de bedoeling om concrete en praktische informatie te geven over hoe je naar duurzaamheid kunt kijken en dit kunt inzetten in studie, werk en daarbuiten.

Polymeren, waaronder plastics, kennen we allemaal uit ons dagelijks leven. Van de plastic draagtas tot computeronderdelen en kopjes. Allemaal worden deze polymeren vervaardigd uit aardolie en afgeleide producten. De producten zijn zeer nuttig en breed toepasbaar, mede door de gunstige eigenschappen zoals …

Climate change is undermining the importance and sustainability of cooperatives as important organizations in small holder agriculture in developing countries. To adapt, cooperatives could apply carbon farming practices to reduce greenhouse gas emissions and enhance their business by increasing yields, …
