Sustainable fertilizers

The municipalty of Skellefteå collect waste from homes and workplaces and produces there own biogasfuell for use in the municipality cars and in the public buses. The Biogas plant turns organic waste into biogas. Food bio waste from homes and workplaces is selected and placed in the brown waste container so that it can be taken to the biogas plant. The fuel that comes from this plant is used in the municipality cars and in the public buses, but it can also be bought by anyone whose car can take such fuel.

The largest and northern most full-scale system for wastewater irrigation of Salix plantations in Sweden.
The local community in Hedemora has long experience in producing biofuel from Salix plantations. The cooperation between Hedemora Energi AB and local farmers has resulted in irrigation of 75 acres of Salix Plantations. The local farmers in the project are guaranteed to sell their biofuel to the local municipal heating plant. As a result the project is contributing to the local production and consumption.

The CTCN hosted a Regional Forum for National Designated Entities under the Climate Technology Centre and Network (CTCN) from West Asia. The Forum was held on 3-4  April 2016 in Cairo, Egypt. 

The CTCN Forum was an occasion to develop and strengthen the regional network of NDEs and their relationship with other technology stakeholders, with a view to identify matchmaking opportunities to secure funding for follow-up actions to CTCN requests or other climate technology activities.

Tal-Ya is a new Israeli company that develops innovative water saving solutions for row-crop agriculture vineyards forestry and the municipal gardening sectors. Collecting and using DEW together with more efficient use of irrigated water represents savings of up to 90% irrigated water. Square cover over a plant’s root system and the surrounding soil (replaces traditional plastic mulch) collects dew during the night and prevents evaporation during the day directing all water to one single point- the root system. Irrigated water is directed more efficiently to the right spot.

What are biodigesters?

A biodigester system utilizes organic waste, particularly animal and human excreta, to produce fertilizer and biogas. A biodigester consists of an airtight, high-density polyethylene container within which excreta diluted in water flow continuously and are fermented by microorganisms present in the waste. The fermentation process is anaerobic, i.e., it takes place without oxygen, and the bacteria responsible for decomposition are methanogenic (i.e., they produce methane, also known as biogas).

Black Soil provides innovative agricultural extension services, combining the application of starter fertilization and water into the furrow at the time of sowing by its own machine that can be retro-fitted to any existing seed drill.

Efficient use of nitrogenous fertilisers can reduce N₂O emissions from agricultural fields. In addition, by reducing the quantity of synthetic fertilisers required, improved management can also reduce CO₂ emissions associated with their manufacture. In this article a variety of fertiliser management technologies are discussed in brief, followed by a discussion on their relative advantages and disadvantages.
