Data to 31/12/2016 THE PILLARS OF OUR DEVELOPMENT MODEL 3 BIOECONOMY AS TERRITORIAL REGENERATION
NOVAMONT is the international leader in the bioplastics sector and in the development of biochemicals and bioproducts obtained from the integration of chemistry, agriculture and the environment. It promotes a model of the bioeconomy as a factor of territorial regeneration, based on three pillars:
REGENERATION OF INTEGRATED PRODUCTS CONCEIVED DEINDUSTRIALISED SITES AGRICULTURAL VALUE AS SOLUTIONS CHAIN Reindustrialisation of no Development of low impact Products and value chains are longer competitive sites thanks value chains through the conceived and designed to to proprietary technologies valorisation of marginal land provide unique and first in the world in order to not in competition with food sustainable solutions for create "bioeconomy production, integrated in local specific environmental and infrastructure", integrated areas and connected with the social problems. with the territory and bioeconomy infrastructure Elements of a system with interconnected broader impacts of the single product THE BIOECONOMY AND THE SUSTAINABLE AGRICULTURE 4
• Promote a sustainable agriculture has a huge relevance since agricultural sector represents bio-based the ground of bioeconomy products • Biowaste “generates” organic matter (compost) bio-energy • Reduction of waste (plastics) sector AGRICULTURE SECTOR CROPS • The mitigating effect on greenhouse Crop gas emissions associated with the residues use of compost in agriculture has feed prodcuts been addressed in several studies and experimental researches. COMPOST food prodcuts • Compost use in agricultural sector increases SOM and tends to neutralize GHG caused by cultivation

Large family materials bio-based, biodegradable, or both Have the same or similar properties as conventional plastics Offer additional benefits, such as • reduced carbon footprint • better functionalities • additional waste management options such as recycling organic material into compost

World consumption of plastics for agricultural applications: 4 million tons * On total films: 20 % mulch films, 30 % greenhouse fims and 50 % silage films* In Europe the volume of plastics in agriculture is around 674KT, representing 1,2% of the total volume sales of plastics in the European market (56MT), 500.000 ton of which are films for agriculture**

Agriculture plastic waste: 5 % of total plastic waste* Some types of plastic wastes (e.g. mulch and silage films) have a high level of impurities when collected from the field: from 50 to 80 % of the initial weight of the film** Mulch films are not easy to recycle (especially thin films) and the raw materials obtained not high in quality Potential negative impacts on the soil when not properly disposed of: White pollution phenomena Plastic wastes in soil have a negative impact on crops growth and development, reducing their yield up to 15%*** Every year 15 000 tons of polyethylene mulch film (<25 µm) are released in European soils**** In Europe stiil 50 % of agricultural plastic is landfilled

NO REMOVAL, NO LANDFILL, MANPOWER REDUCTION
At the end of the crop cycle biodegradable mulch film must not be removed, but should be NO LANDFILLING worked into the soil, in order to properly biodegrade (thought the mineralizing action of soil microorganisms) into CO2, water and feedstock
• COST REDUCTION in terms of manpower (removal, dispose of, transport)
• NET REDUCTION OF PLASTIC WASTE
• REDUCTION OF POTENTIALLY NEGATIVE IMPACTS on the environment when the plastic films are not properly removed and disposed of BIODEGRADATION IN SOIL MATER-BI BIODEGRADABLE MULCH FILMS 11 MAIN FEATURES
Same field performance as conventional black plastic films Specifically used for the mail vegetable crops in open field and greenhouse Possibility of use on crops not normally mulched with plastic non-biodegradable mulches: e.g. processing tomato, rice, vine Thin films: from 15 to 10 µm Black mulch film completely biodegradable in soil (“OK Biodegradable Soil” logo for the mulch film, in compliance with EN 17033 standard) USE OF MATER-BI MULCH FILM 12 EXAMPLES OF CROPS

The control against the Cydia moths in chestnut is quite difficult and C. fagiglandana and C. splendana can cause damage up to 50 % damage fruits
A biodegradable wire impregnated with specific pheromones which, when released in the environment for a period of 70-80 days, stop the mating of adult insects.
• The wireshall be installed prior to the flights start (normally within the first 15 days of June)
• The wire shall be cut in 6 meters segments and clipped to the top branches. The vertical segments shall be installed in the most uniform manner, in at least 1 hectare sized plot of land.

About 50% of worldwide lubricants is left in the environment through total loss applications, evaporation, leakage and accidental losses
Estimated values reaches 70-80% for Biolubricants, differently from mineral oils, if released hydraulic fluids in the environment, do not decrease soil fertility, do not accumulate toxicity in the groundwater and biodegrade in few days
The usage of biolubricants and hydraulic fluids not only provedes environmental benefits, but also technical advantages in terms of safety and performance
