• 3. BENEFITS
• 1. - Circular economy. Facilitating rational use of all the

different waste streams from intensive livestock farming/biogas plants

• 2. - Reduction of environmental impact of animal manure of

intensive livestock exploitations

• 3. Reduction of Nitrogen pressure in the area where the

plant is located

• f activities in rural areas. New jobs related to green

fertilizers production.

• 7. - Improvement of competitiveness of biogas plants and

livestock exploitations – agrifood companies

Trials on lettuce (spring) fertilized with conventional fertilizers and alternative fertilizer (green fertilizer) shower very similar results in respect of weight

• 4. PRACTICAL RESULTS. EXAMPLE: TRIALS IN ITALY

CONCLUSIONS USE OF GREEN FERTILIZER

The green fertilizer is a liquid product and has a low concentration of

nitrogen (18% N) in comparison with existing artificial fertilizers.

After trials of work package 3, it is important to mention that a possible

solution can be horticulture (both open field and in green-house), because fertilizer amount are smaller and there is a higher probability to find small tank of liquid fertilizers. Nevertheless, the GF can be applied in fertirrigation in combinable crops as well.

Also, the low carbon footprint of the GF could be valorised over the

value chain, as the harvested product, mainly fresh consumed, can hold a label telling the consumer “ Produced with S ustainable inputs” .

The product can be used by the owner/producer by complying to the

legislation on digestate management.

The advantage is for location where the nitrogen has to be moved far away Saving 89000 EUR/year for 30000 m3/year of processed digestate

Potential sales of green fertilizer

• Plant 30000 m3/ year selling of fertilizer 170 EUR/ t (1300 t/ year)221 000 EUR/ year –

40000 EUR/ year distribution cost

• The distribution costs could be avoided if sold to a fertilizer producer (but may be we have

to lower the price as well)

• Total investment (plant for 30 000 m3/ year) 353 000 EUR
• Net present value of investment 277 000 EUR (11 years amortization plan)

Advantages and problems

• Potential advantages

What the value for the market? Is the product use sustainable and logistically viable? Could we have some label (e.g. green..) on our main business process or on the fertilizer?

• Potential problems

It is economically sustainable j ust the internal use?

(reduction of transportation costs)

Registration process of the green fertilizer and costs?

REGULATIONS (Major driver in Europe on many issues)

• ITALY

Decreto Legislativo 29 aprile 2010, n.75 In addition, any fertilizer producer should subscribe to the “ Fertilizer producer Registry” Today, it is possible to submit the registration request through an on-line form called “ S

IC procedure” , linked to MiPAAF website

Moreover, for the Italian Legislation, the Green Fertilizer might be considered as a

digestate, and therefore subj ected to all limits and legislation concerning it

Digestate cannot be sold to other farms, but only applied to the land with special permit

and application plans.

The registration is free but the analysis has an average cost comprised between 3000 and

4 000 € and it can take from 2 to 3 years

28

REGULATIONS

• BELGIUM

The service Pesticides and Fert ilizers is in charge of the permits. After the request,

mentioned service will send an invoice for payment of the fee of 1500 € to the Fund of the raw materials and products.

The exemption is granted for a maximum period of five years and may be renewed for

additional periods of up to 5 years

29

• S

PAIN

The Fertilizer Register of the S

panish Ministry of Agriculture, Food and Environment (MAGRAMA) is in charge of the permits to register fert ilizers from organic sources.

The register is for free and it can take from 2 to 3 months.

• 5. COMING ACTIVITIES
