This presentation summarizes the utilization of sunflower byproducts. It discusses how after sunflower oil extraction, large amounts of residues are left, including de-oiled cake, hulls, and stalks. These byproducts can be used for animal feed, biofuels, building materials, and soil amendment. Sunflower meal left after oil extraction is a good protein source for animal feed. Hulls make up 21-30% of sunflower seeds and can be broken down to produce methane through pretreatment with sulfuric acid. Overall, the presentation outlines various ways that sunflower byproducts can find higher value applications.

2. Sunflower is a plant from the Asteraceae family,
Helianthus genus
Sunflower (Helianthus annuus L.) is a nontraditional
crop introduced in India during the year 1969.
Sunflower is the fourth crop in the world for oil
production after palm & soybean Oil.
Sunflower seed contains ∼15 g protein, ∼58 g total
lipid (fat), ∼3 g ash, and ∼24 g carbohydrate with 675
kcal total energy per 100 g.
Oilseeds are mostly used as a source of vegetable
oils.

3. After the extraction process, large amounts of residues and by-
products are available.
The traditional extraction techniques involve the use of a mechanic
press (hot or cold pressing) or solvents.
Byproducts of the extraction of sunflower oil constitute a raw material
with potential for several applications in the food area due to its
chemical composition, including the high content of proteins and
phenolic compounds.

5. De oiled cake
Sunflower seed hulls
Stalks

6. Bio-composite Applications.
Manure
Animal feed - Sunflower meal & Pellets.
Biofuel production.
Bioactive (bioactive compounds include lycopene,
resveratrol, lignan, tannins, and indoles) food packaging.

7. Building products/composites produced from vari-
ous agro-waste materials, including sunflower stalks,
have
Higher mechanical properties,
Lower thermal conductivity and density
Cheaper,
Durable,
Lightweight,
Available in abundance,
Much less abrasive
Environmental friendly
Chitosan

8. Sunflower residue in the soil may be one of
the best alternative practices for replenishing
the depleted soil fertility and improving the
physical, chemical, and biological properties of
the soil in the present era of production.
An amount of 61 and 58.7% of
incorporated sunflower residues was
decomposed in 12 weeks when residues (C : N
ratio 73.1) were added at 1.5 and 3.0 t/ha,
respectively.
its residue contains major plant nutrients in
the range from 0.45 to 0.60% N, 0.15 to 0.22%
P, and 1.80 to 1.94% K

9. Sunflower meal is the by-product of the extraction of oil from
sunflower seeds.
Then they are air-dried to remove the water before storage.
Sometimes they are molded into two forms, namely flour
(ground material) and pellet.
The diet of farm animals should include feed containing a large
amount of protein.
Otherwise, pigs, cows, etc., will not gain weight well.
Main quality indicators of
animal meal:
Protein : min 35%
Fiber: max 20%
Moisture: max 11%
Fat : < 2%

10. Sunflower seed hulls are an abundant waste produced by the edible oil
industry.
Sunflower seeds consist of kernels and seed coats or hulls.
Sunflower hulls represent 21–30% of the seed weight and generally are
considered a waste by-product

11. Pre-treatment (sulphuric
acid) combination of 1%
H2SO4 and 170 °C
temperature gave the
best result and increased
the methane yield to
302 ± 10 mL CH4/g
volatile solid (VS)
